I have a 240 g tank that has been established for about 9 months now and in the past two months i have notice that i have red algae growing on one side of my tank....it stays in the same place on the gravel and doesnt seem to be disappearing or moving to another place...someone once told me that they grow in a place with low flow so i have put a pump near it to increase the flow but it doesnt seem to do anything....is there any other way to get rid of these stuff. oh yeah it is cyanobacteria...(slimy red algae)
