It's not the watts per gallon that really matters. It's the intensity of the light. PC lighting does not penetrate as well as T5 HO's, VHO's or MH's. Alot of the light is reflected back and is lost. There are some clams that you could keep but they are the more brownish colored (I think they are Derasa sp.). The pretty blue and other colors you see would need more light than your PC's can provide.
