Most aquarists recommend about 4-5 watts per gallon. The kind of bulbs also makes a difference, for stoney corals many recommend at least VHO but prefer MH. IMO, you're better off investing in a MH/VHO or MH/PC combinations.You will save a lot of lifeforms and money in the long run. What coral do u have?
