I have a 125g tank with a canopy that has three 250w lights with 20k bulbs and four T5 lights in it, and 240lbs of live rock in it. I placed the LR in the tank to be fish friedly, meaning it has alot of caves in it and the fish (some of them) can swim from one end of the tank to the other without coming to the outside of the rocks to do it. Now that I have become a polyp and zoa addict I find that this set up might not be good for my zoas because most of my tank has alot of shaded spaces in it. My question, how light do the polyps and zoas need?
