I like both these kits, but if it is not necessary to get the 36 LED kit then I would get the 24 LED kit. I will do some SPS in the top half of the tank but the rest will be devoted to some LPS and mostly zoas. The main thing I am trying to accomplish is to keep a clam. The tank Is 36"x15"x20, LxWxH. So which kit?
