I'm thinking of cutting back on the photoperiod in my 30g (36x12x16) reef tank; some of the lower light corals (mushrooms, especially) are not too happy with the light right now, while the rest of teh corals are very happy, so i dont want to 'upset' them. Currently the lighting is 4x39 watt T5s, 2-10000K and 2 actinic. The actinics are on from noon-11 PM and the 10000Ks from 1PM-10PM. My questions are: how fast/slow should I cut back the light, and what might be a good target photoperiod to shoot for?
