I have a 55 gal. Perfecto freshwater tank with fish only. I want to add some plants, but I need different lighting. I have the hood & strip lights that came with the tank ( 2 -15 watt bulbs). Should I get a full hood or a glass canopy with compact flourescent lights? I don't know what would fit with this aquarium, (it has a center brace). This is driving me crazY!!! Thanks.
