Well I still have a hood that came with my tank and I put some incadescent bulbs in there. Is it possible to replace them with Fluorescent bulbs? or do I just need to buy another hood?
You can get a compact minI fluorescent bulb. They are fluorescent bulbs that screw into a regular light socket. I have a couple in my 15 gallon and they work and look awesome. They should have them at most fish stores. I have the same one as in the link, plus another 18W with a bluish tint.
