Filamentous, often found along with Spirogyra in still water. These algae are made up of very long unbranched threads that have a slimy coating; they feel slippery when picked up. Looks yellow-green when under water. With magnification two green star-shaped structures can be seen in each cell; these are chloroplasts.

How do you treat cyanobacteria?
Chemical treatment is the most common treatment method, and also the most damaging to the environment. It involves using copper sulfate and hydrogen peroxide, which cause sudden death or lysis of cyanobacterial cells. Massive amounts of cyanotoxins are being released back into the water.
How do I get rid of filamentous algae?
Filamentous Algae can be removed from the pond by raking. Using Pond Dye will help to limit sunlight into the pond for algae to complete photosynthesis. Reducing the overall nutrient load in your pond will help to keep algae blooms to a minimum. Use PondClear™ or MuckAway™ to reduce overall nutrients.
