I have a stock biocube 29 that finished cycling about 3 weeks ago. This is my second time starting it up. I had an algae problem in the past. So I ask you, what's the best lighting schedule to keep algae away but yet support coral growth? I read somewhere that a 4hr on 2 off and 4 on method was good because it doesn't allow ample time for the algae to grow because of the photoperiod. How much truth is behind that?
