I have recently started up my old 125 gallon cichlid tank. I have about 30 mixed africans and I am currently having a problem with red algae on the glass. I dont run the lights but a couple hours a day but doesnt seem to help. For the last 3 days I have had the lights of the whole time treating the tank with pimafix and melafix and it has made it worse. I am sure that I dont have enough filtration at this time but working on that problem. Could this be the cause of the algae?? Any ideas on getting rid of it? I am currently cleaning the inside of the glass with a paper towl or sponge to remove it. Thanks for any advice!!!
