I have a tank with live plants and a fluval light at 25% for about 1 1/2 hours a day ant at about 70% for about 4 hours a day. I have hair algae I keep plucking out of the tank... It even started to grow on my moss balls. I have three Ottos and guppies in the tank, and they basically ignore the stuff. Does anything actually eat it? If I turn the light way down for a few days will it go away without killing off the live plants? Other suggestions?
