I have a 48 inch ati powermodule over my 90g sps dominated tank. Right now it is 6 inches above the water. My corals have amazing color but I was wondering if I have my daylights on for long enough. I run 2 blue plus from 11:45am to 10 pm and I have my daylights run from 1:45 to 6:15. Are those goo hours? If I keep them on for 8 hours will I get better growth? Or will that bleach my corals? My growth is pretty good right now and everything is looking great, do you think I should just keep it how it is?
