CYANOBACTERIA, Also known as blue-green algae, blue-green bacteria or Cyanophyta, is a

Stromatolites of fossilized oxygen-producing cyanobacteria have been found from 2.8 billion years ago, possibly as old as 3.5 billion years ago.

The ability of cyanobacteria to perform oxygenic photosynthesis is thought to have converted the early reducing atmosphere into an oxidizing one, which dramatically changed the composition of life forms on Earth by stimulating biodiversity and leading to the near-extinction of oxygen-intolerant organisms.

According to endosymbiotic theory, chloroplasts in plants and eukaryotic algae have evolved from cyanobacteria via endosymbiosis.

Red algae, some will use chemi-clean it fouled the whole tank. I went by the instructions and used even a little less than what it said.

Broke down my intire biological and killed most everything in my tank.

The (other) store that told me to use it would not replace anything I lost and blamed it on me.

Go figure!

The name "cyanobacteria" comes from the color of the bacteria (Greek: κυαν?ς (kyanós) = blue).

They are a significant component of the marine nitrogen cycle and an important primary producer in many areas of the ocean, but are also found in habitats other than the marine environment; in particular cyanobacteria are known to occur in both freshwater, hypersaline inland lakes and in arid areas where they are a major component of biological soil crusts.
