There is a strange color on two spots in my tank. The picture is of bad quality but you can see the difference in color. Is this cyanobacteria?
Indeed........But because cyanobacteria is able to fix its own nitrogen it can sometimes apear in a well maintained tank or by introduction of the organism?...but does not usually get rid of the cause...
Cheers,
I am quite sure there are cyanobacteria in all tanks and don't need to be introduced to get goingby introduction of the organism
