I have just started a reef tank in it's second week, and I was wondering how long I should leave my compact flourescents on for ? Right now I have them on for 13 hours a day, but brown algae is starting to grow at an enormous rate (my phophate level is high too, but took care of that). It's probably excessive amount, but when I eventually put corals in the tank isn't 12-14 hours suggested ??
