I have this brown algae on my rocks, plants and sides of my tank. How can I get rid of it? My goldfish eat it when I scrape it off and they even graze on it. Should I stop feeding my goldfish and let them graze on the algae until it is gone??
Can someone help ID this from the pictures?
Are they diatoms?
