Hello. I am a bit confused as to how to eliminate the brown algae problem. My tank has been set up for about 9 weeks now & the brown algae just keeps on getting worse. At first the lights were on for 12 hrs, then I tried 8-10 & now back to 12 hours. It is a 25 gallon with a 20 watt flourescent. My 10 gallon has been set up for 6 weeks now with a 15 watt & it has no brown algae.
Is there enough light in my 25 gallon & how long should I keep the light on?
Thanks
