Aquarium Advice Apprentice
hello. I have a 55 G freshwater aquarium, that's been set up about 4 months now. I have always had the brown algae on the inside of the glass. But now there is other algae growing everywhere, that looks like "hair". The light is on about 12 to 14 hours a day. Is this algae bad to have, and is it because I have the white on too much? I do not know the specs on the light bulb.
