my tank has bloomed into an alge covered mess. the tank is about 6 months old, first i had the brown slimy stuff (diatom?) and now a brownish green stuff has covered all my plants and rocks. i have press CO2 and not sure about the lights(three long flor blubs). the tank is a 72 gallon bow front with discus. i would normally get some ottos but cant because of the discus. any help would be appr.
