I have a 48" Current Orbit Marine LED light fixture on my 75 gallon tank. I have some hammer coral, a torch coral, a colt, a frogspawn, and some mushrooms in there. Everything seems to be doing fine, but I know that it is not enough for more light demanding corals. I am thinking about getting another Orbit Marine fixture so I have more light. In doing some research I came across the Photon 48 fixture from Reef Breeders and am wondering if I would be better off just getting that or if two 48" Orbit Marine fixtures would be OK?
