Im trying to figure out just what watts mean versus types of lighting. Currenty I have a fixture with 2X65 PC's 50/50. I want to have various corals and so have some corals now im my 55g tank. The question is should I add more light and what kind. I can add a 96watt 36" PC for about the same price as 78 watt T5HO 2-36 inch bulbs. Whats going to be better and how does wattage compare with the type (PC, HO, MH) lighting. Does wattage really tell me anything or should I just shoot for T5HO but arent PC's basically conjoined T5's. Any experts wanna line me out?
