Pond Algae:

The arrival of spring often presents a problem for pond owners as the beautiful, clear green water of their ponds disappears beneath a blanket of lime green, slimy, stinky pond scum. "Pond scum" is actually a popular term for aquatic algae, which tend to "bloom," or grow excessively in the early months of spring, spreading over the surface of the pond in unsightly and odorous mats of green and brown. Aquatic algae are primitive plants, having no true roots, stems, or leaves. Pond algae can be found either floating on the pond surface or attached to other plants, bottom sediments or other hard surfaces. There are thousands of species of aquatic algae, but for simplicity they can be classified in three categories: microscopic algae, filamentous algae, and attached-erect algae. Microscopic algae, also...Read more

Algae Biofuel:

Algae can be grown using land and water unsuitable for plant or food production, unlike some other first- and second-generation biofuel feedstocks. Select species of algae produce bio-oils through the natural process of photosynthesis requiring only sunlight, water and carbon dioxide. Growing algae consume carbon dioxide; this provides greenhouse gas mitigation benefits.  Bio-oil produced by photosynthetic algae and the resultant biofuel will have molecular structures that are similar to the petroleum and refined products we use today. Algae have the potential to yield greater volumes of biofuel per acre of production than other biofuel sources. Algae could yield more than...Read more

Pool Algae:

By far the most regular complaint of swimming pool owners is algae. This is because the algae is visible and unsightly. There are over 21,000 species of algae known to man but only a fraction of these are encountered in swimming pools. Algae does not cause disease. It is a plant that turns sunlight and carbon dioxide into food and provides nutrients for bacteria which can then multiply rapidly (and may cause illness). When there is algae present in the pool water, the chlorine is used up rapidly trying to combat its growth. This process has a tendency to raise the pH, thus decreasing the efficiency of the remaining free chlorine. Unchecked algae growth can turn the swimming pool cloudy or makes the pool water green and results in foul odours and tastes. Black algae, which is more difficult to control than green or blue-green algae, can also stain the swimming pool's walls and floor. Prevention is better than cure. Adequate levels of...Read more

Water Algae:

Pond Algae comes in many different forms, even different colors (Green Algae, Red Algae,Brown Algae). The two kinds of Pond Algae frustrating backyard Pond owners most often, though, are "Green Water Algae"(also called Pea Soup Algae) and "String Algae" (also called "Blanket Weed" or "Hair Algae"). Controlling and getting rid of String Algae and Green Water Algae in ponds used to be difficult, but in the last few years many effective and environmentally safe products have been developed to eliminate String Algae and Green Water Algae. This makes it much easier to control and eliminate the String Algae and  Green Water Algae nuisances. Green pond water Algae are single cell plants that can make the Pond look like pea soup. These plants are so tiny that they can pass right through a...Read more

Algae Biodiesel:

The race is on for a new form of fuel. With gasoline skyrocketing to more than $4 a gallon in 2008, dependence on imported oil and depleting resources worldwide, finding alternatives to petroleum-based fuel and fuel-related products is urgent. Fortunately, scientists have been studying the production of alternative products to make a cleaner, greener fuel for years.It's possible that we may be using one of these alternative fuels in the near future. Alga (or its plural, algae) may be the miracle element in the search for a more environmentally-friendly, mass-produced product that can be converted into fuel. Algae grow naturally all over the world. Under optimal conditions, it can be grown in massive, almost...Read more

Tank Algae:

It is normal for algae to begin to return within two weeks after being removed. Algae multiply rapidly. If, however, algae returns within a day or two, this may indicate a problem with either light or water quality. Algae requires light and nutrients to grow. If the tank receives too much light, is over-fed, or is over-stocked, algae problems will usually occur. If the aquarium is a reef tank using metal halide lighting which is on for twelve hours or more each day, rapid algae growth on the aquarium sides could be normal. You should experiment with photoperiod to see if you can strike a balance between algae growth and the health of the corals. Excessive algae growth on a live-reef structure is not normal. Good water flow and alternating flow should exist in a reef tank. Temperature may need control through use of a chiller. Algae consuming animals should be present in every reef, such as Blue-legged Hermit Crabs, Sally Lightfoot Crabs, Snails, and Urchins. Live rock structures should be built with spaces to allow good flow. Excessive light and/or water quality parameters should be checked and corrected if necessary. An over-fed or over-stocked aquarium will result in the accumulation of organics that algae feed on, resulting in rapid algae growth. Warmer aquariums grow...Read more

Saltwater Algae:

Algae growth in your saltwater aquarium is natural. They can either be good or bad depending on whether or not they become unmanageable and get out of control. Pros and cons in your saltwater aquarium will be covered in this section. We'll also learn about their different types, including those that you want to...Read more

Algae Eating:

This table is by no means complete nor may it be 100% correct but it will give you an idea of which species of algae-eating animal you may want for your aquarium or pond.Both the likelihood of eating algae and eating plants applies to adult specimens and not to juveniles. Some species propensity to eat algae varies with age such as with most of the algae- eating fish. The species that are most available at the aquarium or pet store are those that the salesperson is most likely to try to sell to you. They also often cost a lot less than the other, less- available species. Do not let a salesperson sell you an animal that is not appropriate for your particular situation. For example, do not put a common plecostomus in a tank under 40 gallons unless you...Read more

Red Marine Algae:

Red marine algae have been used for a variety of purposes in Asia for more years than have been recorded. Originally probably, used as a food, it then found many medicinal applications for a wide variety of conditions depending upon the species of algae. In fact, one of the earliest written records from China dating to 600 BC mentions algae as being a food suitable for a 'king himself'. In Chinese medicine red marine algae have been looked upon as allowing the flow of qi by removing obstructions to this flow caused by wetness and heat. By maximizing qi we attain a maximum feeling of well being and energy. The algae, then, have been used by the...Read more

Algae Removal:

Green water is caused by the presence of phytoplankton or algae. There are many species of algae, some are suspended, single-cell organisms while others are filamentous or form "strings". Neither type is noted for directly creating health problems for fish but cause problems with water clarity and the overall appearance of the pond. As a result many persons attempt to eliminate the algae by a variety of methods. A few of the methods that have been used for both suspended algae and string algae are listed below in no particular order of preference. Regardless of the approach you may find that you ultimately must deal with reducing the nutrients that fuel the algae growth cycle. Norm Meck has written an excellent article regarding green water and algae control. You can access this...Read more

Kill Algae:

As far as long term removal and control of algae, you will need to control nutrients in the pond meaning excess fish food, fish waste, leaves and grass clippings and even fertilizer run-off. This can be done by a proper filtration system that will filter out these contaminants. Also a good beneficial pond bacteria added regularly will also help to degrade these wastes quickly. Another step would be to aerate/ circulate the water in the pond. Algae hates oxygen so by improving oxygen levels wither with a fountain, waterfall or even diffused aerators, you will also help to control algae...Read more

Algae Treatment:

Natural Algae Treatment
There are several things you can do to lessen or eliminate a mild or moderate algae bloom with out the use of chemicals.

1. Manual rake or pull out all you can reach. Use a soft brush if necessary. Your pump     should be able to pump at least 1/2 of the total volume of your pond every hour.
2. Plant coverage should be 50% - 70% of the surface. Add a variety to compete with     algae for the nutrients. Water lilies will shade the surface of the pond. Submerged     plants (Anacharis) and floating plants (Water Lettuce, Water Hyacinth) absorb     nutrients directly from the water with their roots.
3. Add 1 Barley Straw Bundle per 1000 gallons of water. Keep submerged but do not     let them sink to the bottom of the pond. They need light and oxygen to break     down.
4. Have the...Read more

Chinese Algae:

Though not the most beautiful of fishes, the Chinese Algae Eater is a workhorse when it comes to its job... eating algae! The Chinese Algae Eater is desirous to many aquarist mainly for their ability to keep the aquarium free of algae. This fish prefers hiding places in wood, rocks and plants. Since they graze on algae most of the time, some sunlight on the aquarium to promote the algae growth is appreciated.Their slung mouth forms a sucking disk, perfect for anchoring to a surface especially in fast moving water. Though they prefer algae,
you can...Read more

Swimming Pool Algae:

So, you've been away for a while and come back to find a nasty green slime has invaded your swimming pool. Or maybe a pool party has left your pool looking less than pristine.

Slime Algae:

Red slime algae is actually not a "true" algae at all, but classified as a cyanobacteria. Often considered to be the evolutionary link between bacteria and algae, cyanobacteria are one of the oldest forms of life on earth and date back at least 3.5 billion years. These organisms produce oxygen as a byproduct of photosynthesis, and scientists believe that if it weren't for this microscopic organism, there would be no blue skies on Earth. Commonly referred to as "red slime" algae, the name cyanobacteria literally means...Read more

Siamese Algae:

The Siamese algae eater is also known as the Siamese flying fox, Flying fox and Siamese fox. It is common in aquarium stores and a very good algae eater. A very similar species, Garra taeniata aka Epalzeorhynchus sp, is sometimes sold as Siamese algae eater which have earned that species the common name False siamese algae eater. A majority the Siamese algae eaters that are (or at least used to be) sold in United States are in fact False Siamese algae eaters. It is also common for shipments of Siamese algae eater to contain both Siamese algae eaters and False Siamese algae eater. This is not surprising as the species live in the same areas and...Read more

String Algae:

Green Hair Algae:

Green Hair Algae (abbreviated as GHA for this article) - Derbesia - is a form of algae that looks like its name. It is usually dark green, grows quite long if left unattended and spreads across your tank rapidly. Once this problem has begun, it can get out of hand in a matter of weeks. And soon you start to look at your tank in disgust, thinking Why me? What did I do to deserve this plague?

A number of things may have contributed to it getting a foothold in your system. Your nitrates might be too high, your phosphates may be too high (.03 or less is the goal), your lighting has recently been replaced or perhaps your bulbs are so old that the spectrum of light has shifted, fueling algae growth.
First things first. You need to get your water...Read more

Roof Algae:

Part of my roof gets very little direct sun and is shaded. Both moss and green and black algae grow on the shingles. Are these organisms causing damage to my roof?

All herbivores need algae in their diets. However, virtually any fish will enjoy an occasional offering of algae. If you don't have fresh algae, the next best thing is algae flakes or wafers. Algae wafers are the best option for bottom feeders, while algae flakes are an excellent option for community aquariums. Here are my top algae wafer choices...Read more

Cleaning Algae:

Start by giving the glass a good cleaning on the inside with an algae pad. There are a wide variety of algae scrapers on the market, from long handled scrubbers to magnetic scrubbers. I personally like small magnetic scrubbers, but virtually any algae pad will do. Is it necessary to purchase algae pads at a pet shop instead of the the housewares department of a regular store? Although they may look the same, the housewares pads can have soap or chemical residue. That reside doesn't matter if you are cleaning your kitchen sink, but it can be lethal to your fish...Read more

Algae Diesel:

Solazyme's certification is a milestone in algae-based fuels, one of the hottest areas of biofuels. Algae as a feedstock is more desirable than soy because it is not a food crop, yields more oil, and can grow on marginal land. But, in general, the technology is still experimental and algae-based diesel has not been produced at commercial scale. Solayzme's process differs from most algae farming in that the microalgae is grown without sunlight in a setting more akin to a brewery than an open
pond...Read more

Filamentous Algae:

Filamentous algae are single algae cells that form long visible chains, threads, or filaments. These filaments intertwine forming a mat that resembles wet wool. Filamentous algae starts growing along the bottom in shallow water or attached to structures in the water (like rocks or other aquatic plants). Often filamentous algae floats to the surface forming large mats, which are commonly referred to as "Pond scums." There are many species of filamentous algae and often more than one species will be present at the same time in...Read more

Klamath Blue Green Algae:

Fish Pond Algae:

There are about 4 basic causes of excess algae or an algae bloom.
1. For survival, algae needs nutrition (nitrogen & phosphorus) and sunlight. This can     be in the form of fish waste (too many fish), over feeding fish, decaying organic     matter (leaves & plants), lawn fertilizers and decomposed fish. A build up of     sludge on the bottom of the pond will feed the algae also.
2. New ponds are very likely to have an algae bloom. This is not necessarily a bad     thing. The algae is actually consuming the excess nutrients in the water. Give the     pond time to balance it's self before adding fish as they will only add to the     nutrient overload.
3. Weather and temperature changes. In the spring, beneficial bacteria has only     started to multiply. Plant coverage is not at maximum coverage...Read more

Chlorella Algae:

Chlorella is a genus of single-celled green algae, belonging to the phylum Chlorophyta. It is spherical in shape, about 2 to 10 μm in diameter, and is without flagella. Chlorella contains the green photosynthetic pigments chlorophyll-a and -b in its chloroplast. Through photosynthesis it multiplies rapidly requiring only carbon dioxide, water, sunlight, and a small amount of minerals to reproduce[citation needed].

The name Chlorella is taken from the Greek word chloros meaning green and the Latin diminutive suffix ella meaning "small". German biochemist and cell physiologist Otto Heinrich Warburg, awarded with the Nobel Prize in Physiology or Medicine for his research on cell respiration in 1931, also studied photosynthesis in Chlorella. In 1961...Read more

Algae Problem:

The appearance and growth of algae in an aquarium is not bad, it's just the natural order of things. In fact, it shows that an aquarium is well balanced and healthy, and the cultivation of macro forms is actually beneficial. Only when the algae is allowed to grow out of control and cover everything in the tank is when it becomes a problem. The above contributing factors are what can allow algae to grow into nuisance proportions, and here are suggested standard methods that can help to reduce or...Read more

Algae Shrimp:

oods:  Obviously algae-eating shrimps eat algae.  They also eat fish food (first).  Don't feed them anything if you want them to get rid of your algae.  When they run out of algae, they will eat your plants.  Add food at this point.  They also munch on deceased fish.  We've never seen them attack fish but would not put it past them.  They do not like the blackish, furry algae...Read more

Seaweed Algae:

A seaweed may belong to one of several groups of multicellular algae: the red algae, green algae, and brown algae. As these three groups are not thought to have a common multicellular ancestor, the seaweeds are a paraphyletic  group. In addition, some tuft-forming bluegreen algae (Cyanobacteria) are sometimes considered as seaweeds "seaweed" is a colloquial term and lacks a formal definition...Read more

Algae Hydrogen:

Algae are a promising source of biofuels: besides being easy to grow and handle, some varieties are rich in oil similar to that produced by soybeans. Algae also produce another fuel: hydrogen. They make a small amount of hydrogen naturally during photosynthesis, but Anastasios Melis, a plant- and microbial-biology professor at the University of California, Berkeley, believes that genetically engineered versions of the tiny green organisms have a good shot at being a viable source for hydrogen...Read more

Algae Supplements:

Blue-green algae supplements come in the form of capsules, pills, and powders. An important part of the food chain in lakes and ponds worldwide, blue-green algae are microscopic plants with characteristics of both bacteria and algae (such as seaweed), but are more closely akin to bacteria. The two main blue-green algae types are Spirulina and Aphanizomenon flos-aquae (AFA). AFA is chiefly harvested from Upper Klamath Lake in southern Oregon and then freeze-dried and sold in capsules and other forms. The largest manufacturer is Cell Tech, which sells its "Super Blue-Green Algae" via thousands of...Read more

Algae Filter:

The thought process behind incorporating an ATS into your reef aquarium is two-fold.
1)  To provide a unique habitat for micro-crustaceans, worms and the like (Raabe 2008) to live. These critters process waste, thus cleaning the water of      dissolved organic compounds, and also produce plankton while reproducing in the water stream, thus providing the system as a whole with live food.

2)  To provide nutrient export by harvesting fast-growing turf algae (Raabe 2008)
     Turf algae grows well in the areas of the reef tank where there is high oxygen/gas exchange. The system described here is a simple Perspex or      glass screen over which water is allowed to flow within a portion of the sump. This provides a...Read more

Green Water Algae:

Some of you may recall reading my post, "Green Water Remedies" last week. It detailed my plight to rid my water of the horrible cloudiness that overtook it during antibiotic treatment of diseases beginning on 10/5. By Friday the water was so bad you couldn't see fish 2" away from the glass. I consulted numerous sources for advice and came up with four possible remedies: Light starvation, chemical treatment, diatom filtration, and UV sterilization. Being rather out of funds...Read more

Algae Nutrition:

Chlorophyta is a macroalgae packed with nutrients and used as a food with a good source of phytochemicals. It contains more proteins than Phaeophyta and Rhodophyta.

Pond Algae :

Algae are a natural part of the mini-ecosystem that is your pond and they can be beneficial for inhabitants such as fish and frogs. There are however situations where algae starts growing exponentially and threatens the well-being of the other pond creatures. Such situations should be dealt with as soon as you notice the first signs of trouble and preventive care is even better. Pond algae are commonly divided into three main groups: microscopic algae, filamentous algae and attached-erect algae... Read more

Algae are a very diverse group of organisms that vary widely in size, shape, colour and habit. Ten or so phyla are represented in freshwater. This page gives an overview of some commonly found freshwater algae. The algae have been grouped by their major features. Some of these are artificial groups (i.e. not necessarily related to their taxonomy) but are convenient ones for the pond dipper... Read more

Pond algae is inevitable. These single-celled plants are very hardy and, once many of them form a colony, they turn the pond's surface into an ugly green mess. There are, however, some beneficial types of koi pond algae that one actually should be happy to see sprouting up in their pond... Read more

Algae Biofuel :

Biodiesel is the most commonly discussed energy output from algae, but it is not the only one. A serious study of the energy domain and of algae points to a wide basket of energy outputs that can be theoretically derived from algae - all the way from gasoline to hydrogen to LPG. The following is the list of fuels that can be obtained from algae.

* Biodiesel
* Ethanol
* Hydrogen
* Methane
* Biomass - where algae biomass is directly used for combustion
* Other hydrocarbon fuel variants, such as JP-8 fuel, gasoline, biobutanol etc. .. Read more

Algae biodiesel is made in a similar fashion to all other biodiesel. The main difference of course being that algae biodiesel is made with algal oil, not vegtable oil or animal fat. Once the oil is harvested from the algae, it is combined with an alcohol such as methanol (or ethanol) and a catalyst. A chemical reaction occurs creating a methyl esther (fancy name for biodiesel) and a co-product calledglycerine. The glycerine is separated from the biodiesel and any residual alcohol is recovered from a distillation process and used again. The glycerine can be used for many things such as lotions and cosmetics... Read more

BioFuel produced from Algae. Often called Algae Oil, Algae Fuel or Oilgae is a 3rd generation bio-fule produced from Algae. Vegetable oil, biogasoline, biomethanol, biodiesel, bioethanol, biobutanol and other biofuels can be made from Algae. Algae oils when heated reduce viscosity and so Algae Oil can be burned directly in a diesel engine, or Oilgae can be chemically processed to make other fuels such as biodiesel. Biodegradable so there is practically no damage to the environment if the fuel gets spilled as compared to environmental disasters caused by petroleum oil spills... Read more

Algae fuel :

While a number of bio-feedstock are currently being experimented for biodiesel (and ethanol ) production, algae have emerged as one of the most promising sources especially for biodiesel production, for two main reasons (1) The yields of oil from algae are orders of magnitude higher than those for traditional oilseeds, and (2) Algae can grow in places away from the farmlands & forests, thus minimising the damages caused to the eco- and food chain systems...

Solazyme, a startup based in South San Francisco, CA, has developed a new way to convert biomass into fuel using algae, and the method could lead to less expensive biofuels. The company recently demonstrated its algae-based fuel in a diesel car, and in January, it announced a development and testing agreement with Chevron. Late last year, the company received a $2 million grant from the National Institute of Standards and Technology to develop a substitute for crude oil based on algae... Read more

Algae fuel also called algal fuel, algaeoleum or second-generation biofuel,[1] is a biofuel which is derived from algae. During photosynthesis, algae and other photosynthetic organisms capture carbon dioxide and sunlight and convert it into oxygen and biomass. Currently most research into efficient algal-oil production is being done in the private sector, but predictions from small scale production experiments bear out that using algae to produce biodiesel may be the only viable method by which to produce enough automotive fuel to replace current world diesel usage...

Water Algae :

Aquatic ecologists are concerned with blooms (very high cell densities) of algae in reservoirs, lakes, and streams because their occurrence can have ecological, aesthetic, and human health impacts. In waterbodies used for water supply, algal blooms can cause physical problems (e.g., clogging screens) or can cause taste and odor problems in waters used for drinking. Blooms involving toxin-producing species can pose serious threats to animals and humans... Read more

Freshwater algae lack true roots, leaves, or stems, and instead have simple thalli existing as unicells, filaments, or colonies. Algal taxa are primarily characterized by thallus structure, cell wall structure, pigmentation, and motility, along with other ultrastructural and molecular features. The algae range in size from tiny plankton to enormous kelp hundreds of meters in length, and are found in diverse environments. Like plants, all photosynthetic algae possess the pigment chlorophyll a and release oxygen as a byproduct of photosynthesis.

Algae Biodiesel :

Algae to biodiesel has been widely discussed among experts in the petroleum industry and conservationist who are looking for a more reliable and safer source of energy that is both renewable and easy to attain. One of the key reasons why algae are considered as feedstock for oil is their yields. DOE (Department of Energy, Gov of USA) has reported that algae yield 30 times more energy per acre than land crops such as soybeans, and some estimate even higher yields up to 15000 gallons per acre... Read More

The advantages of deriving biodiesel from algae include rapid growth rates, a high per-acre yield; and algae biofuel contains no sulfur, is non-toxic, and is highly biodegradable. Some species of algae are ideally suited to biodiesel production due to their high oil content--in some species, topping out near 50%... Read More

There's no doubt, algae biodiesel is probably the most theoretical and experimental aspect of biodiesel. Some of the best minds on the planet, including Exxon-Mobil, Shell, even the Department of Defense are racing to be the first to mass produce algal biodiesel... Read More

Tank Algae :

When you have algae growing in your tank, your tank is capable of supporting life on it\'s own, and that life is finding its way into your tank. However, many people do not like to have a coating of algae on everything, as it detracts from the appearance of the tank and makes it difficult to see and enjoy the fish... Read More

Algae is the bane of every aquarium owner. Algae grows in every healthy aquarium, no matter how well, or how often the tank is cleaned. There is absolutely no safe way to completely prevent or stop the growth of algae. Once it starts to grow in an aquarium, it does so very rapidly. A small patch of algae can triple in size in a few days. When one of our clients calls and informs us that their aquarium is "dirty", we know they're referring to algae growth on the tank, or on the gravel or decorations... Read More

Diatoms are single celled algae, brownish in color. It starts out as a dusting on the substrate that rapidly turns into a mat that can cover the tank over in just 5 days. The diatoms are limited inmovement, relying on water current, and generally start at one point expanding rapidly... Read More

Algae Eating :

Algae eater is a common name for many bottom-dwelling fishes that feed on algae. Algae eaters are important for the fishkeeping hobby and many are commonly stocked by the trade.
Some of the common and most popular freshwater algae eaters include:[1]
   •  Fishes of the genus Gyrinocheilus, family Gyrinocheilidae. There are three species in this genus with the Chinese algae eater, Gyrinocheilus        aymonieri, the most common. Small specimens make good community fish but may become territorial when older... Read More

This slender algae eating barb is the only known fish that eats red algae. It comes from the flowing waters of Thailand and the Malay peninsula. It was first brought to Europe in 1962, but became popular in the 1970's when its ability to eat red algae was noticed. The fish is also known as Siamese Flying Fox, and Siamese Fox. It previous scientific name was Epalzeorhynchus siamensis. To those interested in the fine, but admittedly boring details of taxonomy, the genus Crossocheilus differs from Epalzeorhynchus by rhynal lobes (nasal lobes). .. Read More

Amongst the algae-eating, tropical herbivorous marine fish, the yellow tang is certainly one of the most popular in the aquarium industry. In fact, the tangs in general are considered by many to be some of the best grazing tropical aquarium fish. While tangs are great algae-eaters, there are many other algae-eating tropical marine fish that the aquarist should consider. There are also a few from which the aquarist should steer clear...

These names includes grass shrimp, Yamato Nuna Ebi, Yamato shrimp, algae-eating shrimp, Japanese marsh shrimp, and the Japanese swamp shrimp.It is normally found In swamps and marsh land in Japan where it feeds on algae. Their diet also contains other soft plants... Read More

The real attraction of these shrimp is their avowed success in algae consumption, especially soft algaes. They are also rumored to eat red algaes in the absence of other foods. However, like most captive inverts they will choose fish food over algae any day and often will turn on soft leafed plants (especially soft mosses, i.e. java moss and riccia)3 in the absence of softer algae types or fish foods. They will not, however, eat Black Brush Alage (BBA), nor can they combat spot algae on tank surfaces. They are not capable, it seems, of pulling tougher algae with their \" hands\". They eat algae directly with their mouths... Read More

Seaweed Algae :

A seaweed may belong to one of several groups of multicellular algae: the red algae, green algae, and brown algae. As these three groups are not thought to have a common multicellular ancestor, the seaweeds are a paraphyletic group.

Green Water Algae :

Green water or pea soup water is common way to describe the outbreak of planktonic algae in a pond. Planktonic Algae is a very simple organism. It requires has two very basic needs for survival, food and light. Unless you block out the sun, or completely cover the pond in light-blocking floating pond plants, every Fish Pond has sufficient light to grow algae... Read More

Green water pond algae control - There are various methods of controlling the build up of algae bloom, some more permanent than others. Such methods include the use of aquatic pond plants, using shade, using pond algaecides and in my opinion the best method, the use of a UV sterilizer, also known as a UV clarifier or simply as a UVC...

Algae Vitamins :

What we've been interested in is the fact that algae aren\'t completely able to live on their own. This is because they require a source of vitamins. In that respect, they are quite like animals. There is one vitamin, vitamin B12, that plants on the land can\'t make . So if you\'re a very strict vegetarian, you won\'t get it from your food unless you don\'t wash your vegetables very well... Read More

Vitamin B12 in algal metabolism is primarily as a cofactor for vitamin B12-dependent methionine synthase, and that cobalamin auxotrophy has arisen numerous times throughout evolution, probably owing to the loss of the vitamin B12-independent form of the enzyme. The source of cobalamin seems to be bacteria, indicating an important and unsuspected symbiosis... Read More

The researchers, funded by the Biotechnology and Biological Sciences Research Council (BBSRC), found that no algae have the necessary genes to produce vitamin B12. Those that do not require a supply are like higher plants; they have an alternative metabolic process that does not need the vitamin. However, algae that need vitamin B12 cannot make it themselves and must get it from somewhere else... Read More

Pond algae :

Many different types of algae can colonize a pond and trying to completely eradicate all forms of algae from the pond is rarely a good idea. Algae are a natural part of the mini-ecosystem that is your pond and they can be beneficial for inhabitants such as fish and frogs. There are however situations where algae starts growing exponentially and threatens the well-being of the other pond creatures. Such situations should be dealt with as soon as you notice the first signs of trouble and preventive care is even better.

What happens is that during winter, when things slow down and many of us turn off our filters, decaying leaves and other organic matter (including fish waste) begin to break down in the pond. The result is an excess of organic nutrients in the water, which is essentially food for algae growth. Add sunlight and some warmer weather to these conditions, and you have an ideal environment for algae growth, both the green water and string algae varieties.

Water algae
Aquatic ecologists are concerned with blooms (very high cell densities) of algae in reservoirs, lakes, and streams because their occurrence can have ecological, aesthetic, and human health impacts. In waterbodies used for water supply, algal blooms can cause physical problems (e.g., clogging screens) or can cause taste and odor problems in waters used for drinking. Blooms involving toxin-producing species can pose serious threats to animals and humans.
Read More

These organisms are found throughout the world. Simple algaes exist in the Monera and Protista kingdoms. Other algaes are plants. They constitute single-celled or simple multicellular photosynthetic organisms that are important producers-produce their own food by using energy from sunlight to synthesize complex molecules from carbon dioxide and water-both in sea and fresh water. Algae range in size from microscopic organisms to giant seaweeds several hundred feet in length. They contain chlorophyll and other pigments which give them a variety of colors. They manufacture their food by photosynthesis.

Algae Biodiesel
While a number of bio-feedstock are currently being experimented for biodiesel production, algae have emerged as one of the most promising sources for biodiesel production. Though research into algae as a source for biodiesel is not new, the current oil crises and fast depleting fossil oil reserves have made it more imperative for organizations and countries to invest more time and efforts into research on suitable renewable feedstock such as algae.
Read More

The advantages of deriving biodiesel from algae include rapid growth rates, a high per-acre yield; and algae biofuel contains no sulfur, is non-toxic, and is highly biodegradable. Some species of algae are ideally suited to biodiesel production due to their high oil content--in some species, topping out near 50%.

Tank Algae
There are many types of algae. There are also a few organisms that look like algae but are not algae at all. In a healthy aquarium, the algae will be green, and if left alone, will grow hair-like in appearance. Algae that is red or brown may indicate a water quality problem, such as high dissolved nitrate or phosphate levels in the water. Red and brown algae are also common in new tanks, when the aquarium is not yet ecologically balanced. These types of algae are also quite common in saltwater fish-only tanks when the coral decorations are cleaned on a regular basis. The small round green “dots” that form on the sides of a tank are not algae. These are actually populations of Diatoms, microscopic animals that secrete a hard calcium shell on which green algae grows. This type of “algae” is the most difficult to remove.

Algae is generally a good sign. When you have algae growing in your tank, your tank is capable of supporting life on it’s own, and that life is finding its way into your tank. However, many people do not like to have a coating of algae on everything, as it detracts from the appearance of the tank and makes it difficult to see and enjoy the fish. My experience with algacides (algae killers, algae eliminators, algae destroyers, etc. - basically any additive designed and sold to kill algae in your aquarium) show that these algacides kill live plants, are hard on the biological filter and are dangerous to many kinds of fish. In correspondence with the manufacturers, I have not gotten any better answers to these questions than, “It has been in testing for years and we have never had a single problem or complaint.” However, every algae killer I have tried has had disastrous side effects and has done little, if anything, to slow, control, or impede algae growth.

Algae Eating
Algae eater is a common name for many bottom-dwelling fishes that feed on algae. Algae eaters are important for the fishkeeping hobby and many are commonly stocked by the trade. Some of the common and most popular freshwater algae eaters includeFishes of the genus Gyrinocheilus, family Gyrinocheilidae. There are three species in this genus with the Chinese algae eater, Gyrinocheilus aymonieri, the most common. Small specimens make good community fish but may become territorial when older.

The Siamese algae eater (SAE), Crossocheilus siamensis, is a species of freshwater fish in the carp family, Cyprinidae. This bottom-dwelling tropical fish is found in mainland Southeast Asia that includes the Chao Phraya and Mekong basins as well as the Malay Peninsula. Their natural habitats are streams and rivers as well as flooded forests during the rainy season. The Siamese algae eater should not be confused with the Flying fox (Epalzeorhynchos kalopterus) or the False siamensis (Garra cambodgiensis).

Red Marine Algae
• Red marine algae can assist the body’s immune response to viruses. This can help to reduce the number of outbreaks and the severity of your outbreaks.
• Red marine algae can reduce the formation of herpes virus colonies, also helping to reduce the number and severity of your outbreaks.
• Red marine algae can be useful for weight-loss and lowering cholesterol, helping improve your overall health.

Marine algae, more commonly known as seaweeds, come in all shapes and sizes. Algae are not plants, even though they sometimes look like them. The classification system of algae can be confusing, as the classification schemes change as we learn more about them. Interestingly, although they are all referred to as algae, the red, green and brown algae are classified into three different kingdoms: the protists, chromists and Plantae, respectively. The algae all have cell wall structures and are capable of photosynthesis like our plants on land.

Algae Removal
Algae control can be accomplished by reducing plant nutrients (fertilizers). These include phosphorus and nitrogen, minor nutrients such as sulfur and various micronutrients such as iron, manganese, magnesium, zinc, molybdenum, cobalt, etc. This is why algae removal using algaecides often results in weed growth and weed control with herbicides often results in heavy algal blooms.
The nutrients must go somewhere. They will go either into weeds or algae. Algae shade the water so weeds cannot grow. If the problem is excessive weed growth, the weeds take up the plant nutrients in the water so the algae cannot grow. Lakes naturally shift every few years from weeds to algae or from algae to weeds. It all depends on what becomes established first in the season.

Green water is caused by the presence of phytoplankton or algae. There are many species of algae, some are suspended, single-cell organisms while others are filamentous or form “strings”. Neither type is noted for directly creating health problems for fish but cause problems with water clarity and the overall appearance of the pond. As a result many persons attempt to eliminate the algae by a variety of methods. A few of the methods that have been used for both suspended algae and string algae are listed below in no particular order of preference. Regardless of the approach you may find that you ultimately must deal with reducing the nutrients that fuel the algae growth cycle. Norm Meck has written an excellent article regarding green water and algae control.

have a 6-foot diameter 3-foot deep pond with a bog & waterfall circulation stream (1/6 hp pump, 15 gallons per minute). There are 4 koi (with babies), 3 goldfish, snails, lillies and watercress. The moss grows too vigorously in the summer, so I just brush and skim it out about once every couple of weeks. Some things that help reduce moss growth: shade or covering (lillies work to do this), sand, brushing and skimming, optimal amount of feed for fish (no leftovers). If you want to actually kill it immediately, you will need to use an algaecide. GreenClean is very good fish-safe algaecide that does not use copper based ingredients.

Algae Treatment
While a number of methods are currently being used for sewage treatment and industrial waste water treatments at effluent treatment plants (ETP), these are very expensive methods that rely on high-cost chemicals and heavy inputs of energy. As a result, these industries are keen on pursuing a method that can be cost effective and can provide a sustainable, long-term solution for treatment of waste water and sewage.

Chinese Algae
I have had my Chinese Algae Eater for at least three years now. When I bought the fish, it was no bigger than 3 cm, and now it’s a little over 15 cm. They grow very quickly, but slow down once they reach 15 cm. I have heard that this fish can reach 28 cm, but mine has seemed to stop growing. This fish becomes more aggressive as it grows, both towards its own spieces and other aggressive speices. I only have one of these in my tank and it doesn’t display any agression towards the barbs and tetras that it shares its tank with. The only serious agression I saw was when I placed a male Betta in the tank with it. Although the fighting fish occaisionally picked fights with it, the chinese algae eater defended itself accordingly. Mine has its own cave that it defends under a piece of flat river rock.

The Chinese Algae Eater is desirous to many aquarist mainly for their ability to keep the aquarium free of algae. This fish prefers hiding places in wood, rocks and plants. Since they graze on algae most of the time, some sunlight on the aquarium to promote the algae growth is appreciated.Their slung mouth forms a sucking disk, perfect for anchoring to a surface especially in fast moving water. Though they prefer algae, you can occasionally substitute crushed lettuce or spinach. Also, they won’t work in the cold. If the temperature in the aquarium drops below 69 ° F (20 ° C) they will stop eating algae!

Swimming Pool Algae
Green algae is a common swimming pool problem, which may appear as a greenish growth on the floor and walls of a swimming pool, a green tint to the pool water, or greenish material suspended in the pool water. The only swimming pool chemical that will kill an algae growth is chlorine based swimming pool “shock”.

By far the most regular complaint of swimming pool owners is algae. This is because the algae is visible and unsightly. There are over 21,000 species of algae known to man but only a fraction of these are encountered in swimming pools.
Algae does not cause disease. It is a plant that turns sunlight and carbon dioxide into food and provides nutrients for bacteria which can then multiply rapidly (and may cause illness).

Spirulina Algae:
Spirulina is a microscopic blue-green algae that exists as a single celled organism turning sunlight into life energy. It is one of the first life forms designed by nature more than 3.6 billion years ago. Spirulina contains billions of years of evolutionary wisdom in its DNA and is an offspring of earth’s first photosynthetic life forms. Under the microscope, Spirulina is a blue-green color and has the appearance of a spiral of long thin threads.

Spirulina Arthrospira is a planktonic blue-green algae (Cyanobacteria) found in warm water alkaline volcanic lakes and is rich in raw protein and seven major vitamins: A1, B1, B2, B6, B12 (one of the best natural sources for B12, although the bioavailability its B12 is in dispute by many researchers), C and E. It naturally contains beta-carotene, color enhancing pigments, and whole range of minerals. In addition, Spirulina has a 62% amino acid content and contains all essential fatty acids and eight amino acids required for complete nutrition. Evidence as recent as late 2007 shows even more proof as to the profound anti-oxidant properties of Spirulina.

Slime Algae
Red slime algae is actually not a “true” algae at all, but classified as a cyanobacteria. Often considered to be the evolutionary link between bacteria and algae, cyanobacteria are one of the oldest forms of life on earth and date back at least 3.5 billion years. These organisms produce oxygen as a byproduct of photosynthesis, and scientists believe that if it weren’t for this microscopic organism, there would be no blue skies on Earth.

Very slimy, when disturbed comes off in sheets. Grows quickly and covers all surfaces in the aquarium, often giving off an unpleasant swampy or fishy odor. Cause:
• Cyanobacteria
• High levels of organic wastes
• Anaerobic conditions Also referred to as slime or smear algae, blue-green algae is actually the organism cyanobacteria. Overgrowth of this organism generally occurs when there are high levels of dissolved wastes and nutrients in the water. Read More

Siamese Algae:
Whatever their scientific name is, Siamese Algae Eaters are good aquarium fish, and they’ll eat lots of algae. But the regular Chinese Algae Eater is not a good aquarium fish. Chinese Algae Eaters will often attack other fish. Plecostomus Catfish are also good aquarium fish that eat lots of algae. Click here for information about Plecostomus Catfish.

The Siamese Algae Eater is generally considered to be the best all-around algae eater available to aquarists. Unfortunately it is easily confused with other similar species (usually “False Siamensis” Epalzeorhynchus sp.), and is often mislabeled in stores. Most of the fish I’ve seen in Canada sold under the name “Siamese Algae Eater” are really Epalzeorhynchus sp. A relatively peaceful fish, especially when young, it can become agressive to its own species as it ages, and its quick, darting movements can stress out some more sensitive fish, such as dwarf cichlids or discus. A very hardy fish, it is easy to keep and feed, eating both algae and just about anything else put into the tank, such as flake food, pellets, live foods, parboiled vegetables, etc. It does a diligent job of removing algae from plants without harming them, as well as from decorations and aquarium glass. Considered by this aquarist as a necessity in any well-planted aquarium. Cover the tank carefully however, as these fish are strong jumpers.

String Algae:
String algae can grow attached to most type of surfaces, such as rocks, aquarium decorations and pond equipment. String algae can also fill the surface of the water and is then commonly referred to as blanket algae.
String algae will typically enter the pond or aquarium attached to plants. Follow standard cleaning protocol before you allow any new plants into your aquarium or pond. Also keep in mind that string algae can be attached to aquatic vertebrates or float around in the water bag when you purchase new fish. Read More

String Algae is caused by a filamentous species of algae, which grow in long strands. These algae eventually tangle together, forming thick mats that can double their weight within 24 hours. Blanket weed or string algae tend to adhere to rocks and waterfalls, which can be unsightly.String algae is the algae that hangs from rocks in the waterfall, attaches to plants or simply hangs on the surface of the water (then called Blanket Algae). Do not confuse string algae with the soft, velvety, jelly-like coating that forms on the sides of the pond. This is good algae. The fish like to eat it and it contains beneficial bacteria. When your pond has this kind of algae, generally, it is balanced. String algae can be brought in by water plants so pull off any stringy algae you see on new plants before introducing them into your pond. Read More

Green Hair Algae:
Green Hair Algae (abbreviated as GHA for this article) - Derbesia - is a form of algae that looks like its name. It is usually dark green, grows quite long if left unattended and spreads across your tank rapidly. Once this problem has begun, it can get out of hand in a matter of weeks. And soon you start to look at your tank in disgust, thinking “Why me? What did I do to deserve this plague?”
A number of things may have contributed to it getting a foothold in your system. Your nitrates might be too high, your phosphates may be too high (.03 or less is the goal), your lighting has recently been replaced or perhaps your bulbs are so old that the spectrum of light has shifted, fueling algae growth. First things first. You need to get your water parameters to Natural Sea Water levels: Read More

Roof Algae:
*People who live in all parts of the nation and have roofs made from all sorts of materials, wood, metal, asphalt, clay or concrete tiles, etc. can have moss and algae accumulate on their roofs. Those places that receive more rainfall and have sustained high levels of humidity have more moss and algae growth as the moss and algae need water to grow and multiply
If you have ever noticed that your roof shingles are streaked with uneven black or green marks, you are likely seeing roof algae. Roof algae lives off of the materials that shingles are made from--mainly limestone or calcium carbonate. The microorganisms do not cause the shingles harm, but many homeowners choose to clean their roof to make their home more aesthetically pleasing.

Algae Killer
* For Structural Applications: Apply Moss & Algae Killer at the rate of approximately 1 gallon per 100 square feet. For best results, moisten area to be treated with fresh water before applying product. Spray area until thoroughly wet. Treated mosses, algae, lichens, and liverworts will discolor quickly. For best results, leave spray on area for 10 minutes following application, then scrub using a push broom or similar type broom, then hose off with fresh water.
I have green algae which I get every year in my swimming pool. I thought I had green algae killer at home but it black algae killer. Do you think it is ok to use this black algae killer in the hopes it will work the same and prevent the green from coming back? I guess it won’t hurt to throw it in the pool?

It is thought that the seaweed was accidentally released into coastal waters of the Mediterranean Sea just below the Oceanographic Museum of Monaco in 1984. Ten years later, Caulerpa had grown to cover 7400 acres (Bright 1998), preventing native plants from growing and leading to the nickname “Killer Algae”. Caulerpa overgrows the seabed and distrupts the food cycle dependent on the native plant life. The plant began to spread between ports along the Mediterranean coast. C. taxifolia has been discovered off the coasts of Australia and the United States, though none of these encroachments have been anywhere near the scale of what is happening in the Mediterranean.

Cleaning Algae:
* For stubborn residue on the glass, use a razor blade to scrape it off. Take care not to cut yourself. If your aquarium is acrylic, use a plastic razor blade, as standard razors will scratch acrylic
There are many tools to use to do this. All of them involve the same process. You use a scraper that is attached to the end of a stick to actually scratch and scrape away the algae from off the sides of the tank. You can get these special scrapers from any pet store that sells fish and aquarium supplies. Some scrapers come with a sponge on the other end, that can also be used to scrape away algae from the sides of the tank. Do this every time you clean your aquarium to keep the algae at a minimum.

Algae Diesel
• Algae biodiesel has virtually no sulfur content.
• Biodiesel has superior lubricating properties, reducing fuel system wear, and increases the life of fuel injection equipment.
• Algae biodiesel has more aggressive solvent properties than petro diesel and will dissolve leftover varnish residue. Fuel filters should be changed shortly after introducing biodiesel into systems formerly running on petrodiesel to avoid clogging.
• Biodiesel has about 5-8 percent less energy density than petrodiesel, but with its higher combustion efficiency and better lubricity to partially compensate, its overall fuel efficiency decrease is only about 2 percent.

Solazyme Inc. is harvesting brown paste made of sugar cane waste and mixing it with algae and water. The algae inhales the sweet-smelling treat -- filling themselves with fatty oils, doubling in size every six hours. The result? A slightly viscous liquid.
After drying the algae, wringing out the oil and shipping it to a refinery, their prize is revealed: diesel fuel that CEO Jonathan Wolfson says is chemically indistinguishable from its petroleum-based equivalent and which has already powered a Jeep Liberty and a Mercedes Benz sedan.

Filamentous Algae
At first glance, you may think hair algae would be single-cell loners in your pond much like planktonic algae. However, they are unicellular, but the cells enjoy the company of other filamentous algae cells. As a result, this algae grows together in thick, hair-like strands that cling to pond surfaces. There are several species: Spirogyra, Cladophora and Pithophora. Lake KIamath is nature’s last pure ecological niche for the production of Blue Green Algae on our planet, “nature’s first and foundational mother and father generic engineering prototype for photosynthesis,” standing at the very basis of the food chain.
Read More

Filamentous algae are single algae cells that form long visible chains, threads, or filaments. These filaments intertwine forming a mat that resembles wet wool. Filamentous algae starts growing along the bottom in shallow water or attached to structures in the water (like rocks or other aquatic plants). Often filamentous algae floats to the surface forming largemats, which are commonly referred to as “Pond scums.” There are many species of filamentous algae and often more than one species will be present at the same time in the pond.

Salt Water Algae
Many types of algae grow naturally in salt water. When reef aquariasts talk of desirable algal growth, they usually refer to coralline algae. Coralline algae is a hard, pink to purple encrustation. This tough pink algae spreads well under the right conditions and can outcompete other, less desirable types of algae. It can be introduced to your reef tank with live rock purchased through any salt water aquarium supply outlet.

Fish Pond Algae
The good pond algae extends over all the sides and other fish pond surfaces. This type of pond algae grows to about 2 cm ( almost 1) in length. It becomes a haven for microscopic life on which the fish feed happily. It remains this length and is an asset in the pond. Do not try to remove this type of pond algae. The not so good pond algae is the suspended kind. It is normally a green-coloured pond algae but may also be in shades of brown. The immediately obvious symptom is a fish pond looking like pea soup. This green pond algae is typically only 4 microns in diameter so that not even the best pond filters can remove it.

Since algae thrive for the same reason the plants in your garden thrive, in order to control algae in your pond, you will need to control one or all of these factors. We will obviously ignore the water factor, since we do not have a pond at all if we do not have water. That leaves us with light and nutrients as elements we can control.
Pond algae control is very important for a healthy pond. There are a few reasons why your algae has increased, causing you to need pond algae control products: too many fish and therefore too much fish waste, decaying organic matter, weather and temperature changes, etc.

Cleaning algae off of a composition roof is not as crucial as cleaning moss off of a composition roof but it is important. Algae usually manifests itself by causing a dark discoloring of your roof. On a white roof the results are of course much more noticeable than they would be on say a black roof. Cleaning off this algae can return your roof to its natural color which makes a very noticeable and a very desirable change in appearance. The aesthetic benefits are of value but are not the most important factor to consider. Though algae is not as immediately damaging as moss it can take its toll on your roof.

Red Slime Algae
*Commonly referred to as “red slime” algae, the name cyanobacteria literally means “blue-green” algae. Despite the naming, only about half of these organisms are actually blue-green in color. Most forms found in saltwater are other colors, ranging from blackish green to blue-green, from orange-yellow to reddish-brown, and often appear deep purple to fully black in color. Starting out as small patches, it spreads out from there as a mat of sheeting covering.
Cyanobacteria appear in both salt- and freshwater setups and are known as red slime or blue-green algae.

Cyano is a hybrid, a mixture between plant and bacteria. It has therefore plant, as well as bacterial characteristics and is considered the evolutionary link between plants and bacteria. The “algae-bacteria” is always present in each setup. Cyano is unicellular. It cannot be detected even when using a common microscope. What can be seen as slime are thousands of cells bound together by a protective slime coat, while some break away floating freely in the water.
Cyano, being a hybrid, is difficult to remove. Factors for growth are multiple and dealing with the algae-bacteria needs to be on multi levels in order to be effective.

Cyanobacteria or “Red Slime” algae are probably on every reef keeper’s top-ten list of biggest problems in their systems. Stories of hobbyists breaking down entire systems, performing huge water changes or even resorting to the use of dangerous medications, only to have the slime quickly return are not uncommon.Recently, one of my personal tanks became heavily effected so I thought I would take advantage of the situation and write an article with the details of the infection and how I handled it.

Algae Bioreactor
*By using algae as a biofuel, we can increase the world’s supply of oil while at the same time we decrease the amount of atmospheric carbon dioxide used during its production. The resulting product is a sustainable biofuel whose carbon footprint is neutral inasmuch as the CO2 produced on consumption is essentially balanced by the CO2 used in its production. In this instructable, we first make the carbon dioxide delivery system, then mount the water bottles on a rack, and then inoculate the bottles with algae. After letting the algae grow for a week, we extract the biomass.
An algae bioreaction system that recycles CO2 from power and manufacturing plant flue gases and converts it to an onsite, continuous supply of biofuel, such as biodiesel, ethanol or methane has been licensed to the Victor Smorgon Group (VSG) by GreenFuel Technologies of Cambridge, Massachusetts. VSG is to have exclusive license to distribute, install and operate GreenFuel’s Emissions-to-Biofuels™ proprietary technology for growing, harvesting, and processing biomass and products derived from algae throughout for Australia and New Zealand.

In an effort to forestall climate change, the US government talks about sequestering CO2 deep in underground shafts and mines. Seems like a wasted effort to me. I’ve said before that society has to start thinking of CO2 as a useful feedstock input and a valuable resource and not as a waste byproduct.
The next issue of New Scientist (Vol. 191 No. 2572) (story embargoed till Oct 7, 2006) will feature a story on algae-based bioreactors that scrub CO2 from power plant smokestacks to eventually produce biofuels. It’s titled FROM SMOKESTACK TO GAS TANK

Chlorella Algae
Chlorella pyrenoidosa, a freshwater single-celled green algae, is more popular in Japan as a regular supplement than vitamin C. An estimated 5 million Japanese use this medicinal algae every day. Chlorella’s broad spectrum health benefits, amply researched by Japanese scientists, include the impressive fact that it contains 60% protein, including all the essential amino acids, and high levels of beta carotene and chlorophyll.

It is to chlorella’s high chlorophyll content (more chlorophyll per gram than any other plant) that many researchers and enthusiastic users attribute its multiple health benefits.

Both scientific documentation and reliable anecdotal reports indicate that chlorella is effective in helping to reduce the symptoms of numerous types of cancers, diabetes, low blood sugar, arthritis, AIDS, pancreatitis, liver cirrhosis, hepatitis, peptic ulcers, viral and bacterial infections, anemia, and multiple sclerosis.

Chlorella is the common name given to an entire genus of green algae, which is primarily found, in nature, in the Far East in freshwater ponds, streams and rivers, giving many of them a characteristic green color. There have been many scientific studies performed on the benefits and effects of chlorella over the years, starting in the early twentieth century.

Algae Problem
I have had a number of conversations with various members in the past few months about algae problems. In fact, this subject came up so often on the Home Show tour, that Lee Finley laughingly suggested that we devote an entire issue of “The Daphnian” to the subject, or at least form a new study group, (Algae Growers of America?)
Well, for those of you who are members of the Aquatic Gardeners, you know they beat us to it. They recently published an issue almost competely devoted to articles on algae.

Presuming you are starting with no-so-healthy cuttings from an unsuccessful tank, so that most of the leaves have firmly attached algae, you must grow out new leaves as quickly as possible so you can eliminate the dying leaves. This is the job of the suggestions presented above. In the mean time, cut off any leaves that are badly covered, and as soon as a stem grows tall, cut it off at the point where the algae starts and replant the top, and discard the bottom. For rosette plants just cut off the infested leaves when sufficient new ones have grown.
For me this has been sufficient to eliminate all algae problems (to the point of no visible algae) when I followed the setup techniques outlined above in some of my tanks. However, this does not eliminate the chance that variations in your tap water chemistry and fish feeding habits will make your job more difficult.

Algae Shrimp
* If you need an algae eater for a small tank (or tank with small fish), put algae-eating shrimps on your payroll. Keep yours covered. We’ve watched them crawl out. They are not helpless out of the water. They run like a cockroach.
I bought 6 of the supposed “Japanese algae-eating shrimp” about a month after I had set up my tank. I say “supposed” because I have read in a number of places that they are often mislabelled in stores so I am not really sure if they are the right ones or not. And, in any case, they probably have too much access to other food (fallen flakes, pellet residue, spirulina wafers, etc.) that they seem to have little interest in algae. But anyways, around the time that the first one moulted (I thought it was a carcass) I never seemed to be able to account for them all, so I assumed 1 or 2 had died. The ones I could see always seemed to be hiding under the piece of wood on the bottom. Several weeks later I noticed a number that were out and active around the tank, and when I counted them I could see 6 again. I was pleased that they had only been hiding. An hour later I recounted and this time I could see 7! Based on what I’ve read, I’m very surprised that they have spawned.

These shrimp are diligent consumers of algae, and are one of the few species available which will consume black brush algae, a particularly troublesome form of red algae. It should be noted, however, that they generally prefer fish food to algae, and will only resort to the latter if the former is unavailable. Also, due to their small size, a large number of them may have to be employed to make a serious impact.
If you see your shrimps at the surface a lot then this is probably due to lack of oxygen or high nitrate levels.

Seaweed Algae
* Two specific environmental requirements dominate seaweed ecology. These are the presence of seawater (or at least brackish water) and the presence of light sufficient to drive photosynthesis. Another common requirement is a firm attachment point. As a result, seaweeds most commonly inhabit the littoral zone and within that zone more frequently on rocky shores than on sand or shingle.
Most people know two general categories of seaweeds: wracks (members of the brown algal order Fucales such as Fucus) and kelps (members of the brown algal order Laminariales such as Laminaria), and many have heard of Carrageen or Irish Moss (usually a red alga, Chondrus crispus) and Dulse or Dillisk (also a red alga, Palmaria palmata). Seaweeds make up the Sargasso Sea, a large ocean gyre in the western Atlantic where drift plants of several species of the genus Sargassum accumulate.

Edible seaweed plants have been used in many countries for food for thousands of years. Left the Marine Plants & Algae with the reputation for: Enhancing Health, Boost Immunity and ability to detoxify. Scientists have discovered that Seaweed’s defend themselves against specific pathogens (Ill making bacteria/micro-organism) with natural antibiotics. Having to live in polluted waters and as result in permanent contact with these potentially dangerous microbes. (Pathogenic) As a result developed a unique defence to fight disease. The seaweed are not only very effective in this respect but found selective way’s of defending. Selectivity is very important because there are many bacteria or micro-organism that are essential to humans and there health. We know that the human digestion system contains a population or a range of bacteria which are not only essential to the digestion but also will fight the intruders and strengthen the immune system.

Algae Hydrogen
Biological hydrogen production is a method of photobiological water splitting which done in a closed photobioreactor based on the production of hydrogen by algae. Algae produce hydrogen under certain conditions. In 2000 it was discovered that if C. reinhardtii algae are deprived of sulfur they will switch from the production of oxygen, as in normal photosynthesis, to the production of hydrogen.
Read More

A microscopic green algae -- known to scientists as Chlamydomonas reinhardtii, and to regular folk as pond scum -- was discovered more than 60 years ago to split water into hydrogen and oxygen under controlled conditions. A recent breakthrough in controlling the algae’s hydrogen yield has prompted a Berkeley, California, company to try to be first to commercialize production.
Energy experts -- who disagree on the when, but not the if, of the eventual depletion of fossil fuels -- are predicting that within decades the world will switch to a utopian hydrogen economy, where energy will be abundant, inexpensive and nonpolluting.

Algae Supplements
Blue-green algae supplementation is a serious mistake, especially for those with inflammatory bowel conditions. The supplements come in powder, tablet and frozen liquid form. They are praised for their high quantities of nutrients, including protein and all essential trace minerals, some of which are typically scant in even organically-grown fruit and vegetables. Are these products really suitable for ingestion by humans? After examining the facts, the answer is a resounding “no.” Here are four major reasons why:
1. B12 Analogues
Most researchers concur that the use of inactive vitamin B12 analogues (“fake” B12, or “pseudo vitamin B12”) found in multivitamin supplements containing vitamin B12 as well as spirulina, chlorella and blue green algae, can deplete, destroy and interfere with active (true) vitamin B12 by competing for the same cell receptor sites.

Indeed, the algae is still a major source of nourishment in some areas of the world. The World Health Organization uses blue-green algae supplements to boost the health of malnourished children in India.
It may be full of salubrious goodies, but at $50 to $70 for a month’s supply, it isn’t necessarily a smart buy. The foul-tasting supplements are meant to be taken in small doses -- too small to be a significant source of protein or beta-carotene. Unless you’re malnourished, your body will barely notice these extra nutrients. If you want more of them, foods such as tofu and nuts (for protein) and green bell peppers and oranges (for beta-carotene) may be more economical and tastier choices.

Algae Filter
I just read an article about turf algae filters. I am happy with my setup with a protein skimmer and doing water changes and am not looking to change it, but the idea of a turf algae filter intrigued me. Does anyone know about these contraptions and if they work. This isn’t urgent, i’m just kind of curious.

Algae Scraper

I don’t know about you, but my tanks are not perfect. Occaisionally I actually have to take a razor blade and scrape the glass on my show tank. The glass is 48” wide and 22” high. With one razor blade on a stick, it takes forever. SO ... this past Saturday I created a razor-blade holder that holds 6 blades edge to edge. It takes me about two minutes to clean the entire front of my tank. Describing how to make this thing in words would overload the APD so I drew pictures of it.

Are you trying to get that encrusting coralline algae or the red algae off the front viewing panel of your aquarium? Sometimes even the green algae can be tough to scrape off. No matter how many times you go over it with that magnetic algae scraper it just won’t come off! Grrr. Sounds like it’s time to come up with your own device for algae control. This DIY tool works on red marine algae, green algae, brown algae or any others that will grow on the fish tank glass. This tool is only recommended for glass tanks. Do not use this on an acrylic tank!

Green Water Algae
Green water is nothing more then single celled planktonic organisms The most common type of blooming “algae”, Euglena, consists of hundreds of species. Planktonic algae are unicellular organisms not clearly characterized as plant or animal. As all protists they have both, plant and animal like characteristics.

Equipped with flagella the protist is mobile, allowing the organism to move towards the light. Phothosyntesis is one of the energy sources this organism utilizes.

Greenwater is often used by fish keepers as a source of live fishfood for newborn fish fry. Ghost shrimp larvae and daphnia also require large amounts of greenwater in their diets.

There is sometimes a need to get rid of greenwater in a show tank and/or water garden because you can’t see past a few inches into the water once greenwater starts to bloom.

Algae Nutrition
Algae species range from the microscopic to the massive mats of kelp vegetation that float on the surface of the ocean. Of the many species of this plant family, only certain species are fit to consume. From the nori sheets that encircle your sushi to dulse and certain kelps, edible algae is becoming more well known for its nutritional benefits and properties

The problem stems from today’s practice of overfarming and the use of artificial fertilizers and pesticides. These chemicals exhaust the soil of its nutrients and kill off the micro-organisms that change inorganic minerals into organic form. As a result, we can no longer rely upon the nutritional quality of our food. Indeed, the vegetables and fruits in our supermarkets can have only fractions of the vitamins and minerals that they had earlier this century.

My algae constitute the largest group of organisms that fix carbon dioxide from the atmosphere, which means they take the carbon dioxide and turn it into sugars. They use the energy of the sun to do that. Algae are responsible for about 505 of the world’s carbon dioxide fixation, so they’re very important in terms of global carbon cycles. What we’ve been interested in is the fact that algae aren’t completely able to live on their own. This is because they require a source of vitamins. In that respect, they are quite like animals. There is one vitamin, vitamin B12, that plants on the land can’t make . So if you’re a very strict vegetarian, you won’t get it from your food unless you don’t wash your vegetables very well.
Read More

Despite this, the role of the cofactor in algal metabolism remains unknown, as does the source of the vitamin for these organisms. A survey of 326 algal species revealed that 171 species require exogenous vitamin B12 for growth, implying that more than half of the algal kingdom are cobalamin auxotrophs. Here we show that the role of vitamin B12 in algal metabolism is primarily as a cofactor for vitamin B12-dependent methionine synthase, and that cobalamin auxotrophy has arisen numerous times throughout evolution, probably owing to the loss of the vitamin B12-independent form of the enzyme. The source of cobalamin seems to be bacteria, indicating an important and unsuspected symbiosis.

Super Algae
Klamath Lake in Oregon is a pristine source of Klamath Lake blue-green algae. Blue-Green (Klamath Lake) Algae is one of earth’s most concentrated sources of protein and chlorophyll, important for keeping blood and tissues strong.
Super Algae maximizes protein, amino acid, chlorophyll and beta-carotene content of each algae species, providing a balanced, nutritional formula.
Nature’s Sunshine combined spirulina, Klamath Lake blue-green, and chlorella to create a synergistic Super Algae formula. These three popular species were scientifically blended to maximize the unique nutritional benefits of each algae.

Pond Algae
Algaculture is a form of aquaculture involving the farming of species of algae.
The majority of algae that are intentionally cultivated fall into the category of microalgae (also referred to as phytoplankton, microphytes, or planktonic algae). Macroalgae, commonly known as seaweed, also have many commercial and industrial uses, but due to their size and the specific requirements of the environment in which they need to grow, they do not lend themselves as readily to cultivation.

Pond Algae comes in many different forms, even different colors (Green Algae, Red Algae,Brown Algae). The two kinds of Pond Algae frustrating backyard Pond owners most often, though, are “Green Water Algae”(also called Pea Soup Algae) and “String Algae” (also called “Blanket Weed” or “Hair Algae”). Controlling and getting rid of String Algae and Green Water Algae in ponds used to be difficult, but in the last few years many effective and environmentally safe products have been developed to eliminate String Algae and Green Water Algae. This makes it much easier to control and eliminate the String Algae and Green Water Algae nuisances.

Types of Algae and How to Control Them
* Many hobbyists see algae as an invasion. They are “like weeds”, choking out the good plants and just generally messing up the tank environment. But nature cannot be blamed for what it does... it is what it is. Algae is a natural part of the water systems on this planet. Don’t hate it because it happens to show up in a luxurious environment that you yourself have setup. At the very least, algae is pointing out some sort of imbalance in your aquarium setup that needs to be corrected.

Types of Algae
Algae Description and Types
* The word algae represents a large group of different organisms from different phylogenetic groups, representing many taxonomic divisions. In general algae can be referred to as plant-like organisms that are usually photosynthetic and aguatic, but do not have true roots, stems, leaves, vascular tissue and have simple reproductive structures. They are distributed worldwide in the sea, in freshwater and in moist situations on land. Most are microscopic, but some are quite large, e.g. some marine seaweeds that can exceed 50 m in length.

Types of Algae
* Some people dread having algae, while others welcome it into their tanks. Like it or not, algae is part of your aquarium. Given the proper conditions, algae will flourish and can even be considered a sign of a healthy aquarium.
What is Algae? The complete answer to that question is beyond the scope of this article. For our purposes, algae is a photosynthetic organism that needs light, water and nutrients to prosper, elements which are readily available in an aquarium. Eliminating it from your aquarium would be practically impossible. Knowing that, controlling and even utilizing algae should be your goal.

* Algae are simple, autotrophic organisms that can synthesize their own food by means of photosynthesis. The taxonomy of algae is very confusing. Previously, algae were classified under the kingdom Plantae, as they possess chlorophyll for photosynthesis. However, algae are mostly aquatic and lack true roots, stem and leaves, which are not so in plants

Freshwater Algae Types
* In a non-planted aquarium,
nitrate and phosphate levels can easily go high, and result in an algae outbreak. Overfeeding and overstocking is the most common reason for water quality going bad like that. Weekly water changes are the best solution in reducing these nutrients. The ammonia (NH3), ammonium (NH4) and nitrite (NO2) levels should be at 0 ppm. Nitrate (NO3) levels should ideally be kept below 10 ppm (nitrate levels over 40 ppm can be dangerous for some fish and invertebrates). Phosphate (PO4) levels should be kept below 0.5 ppm. Lights should be on no more then 10 hours per day. Note that most algae favours strong lights, so placing the aquarium away from the window is a good idea. Direct sunlight will almost certainly cause an algae outbreak. An algae eating army will help a lot in combating algae.
