I've got a 150 watt, 20"x8" double-sided screen ATS on a 125 gallon system. By the numbers, I could feed up to 15 cubes a day. My tank is lightly stocked at this point-- I moved the livestock out of a 30 gallon system and haven't added much more yet. I'm currently feeding the equivalent of around 3 cubes a day, and after three months, I'm now getting some decent green growth on the screen. So the question is, how should I ramp up the feeding? Should I just start feeding 5, 10 or 15 cubes, or slowly ramp the feedings up? I don't have enough fish and coral yet to consume 15ml/day of food, but the current ones would appreciate some more food, I'm sure. Anyone have any thoughts?
