If you are talking about 65W CF
, then you might have algae issues there. If you don't want to stick to the stock hood, then I would say get a shop light, or t5 fixture. I have a fixture on my 55G now that has 4 48" t5's, and it's a bit much for it. I should have gotten the 2 bulb fixture instead. And with the 2 t5's you could do one as a regular daylight bulb, and one as actinic. Or if you went with the 4 bulb like I did, then 2 daylights and 2 actinics would work. I have 4 daylights and am really starting to get algae all over everything.
