FACTS: Much of the muck you see in slimy green water is composed of blue-green algae! (Blue-green algae is the common name for cyanobacteria.)
Cyanobacteria are found worldwide and in many differnet habitats. They grow in fish tanks and swimming pools, as well as innumerable marine and freshwater environments. They are also found in soil, houseplants and as symbiotes in animals and plant-life. They can be soiltary or colonial and can form large mats and filaments visible to the human eye.
Anabaena is a type of blue0green algae that likes to foem filamentous colonies of green slime. They smell bad, taste worse and can cause nausea if ingested. (Prolonged exposure can also cause skin irritation)
Blue-green algae like light and warm stagnant water, so improving water circulation helps to control their numbers. Live plants can also reduce algae populations by providing shade and competition for nutrients. Certain animals, such as tadpoles and algae eating fish, can disrupt algal communities. And where ecological sensitivity is not required (e.g, in swimming pools) chlorine and algicides provide defenitive and catagorical results.
