Out of the ones that have been mentioned so far I would pick the Nova Extreme. I ran the 48" model over my 90g and had no issues. Does not have individual reflectors but, the reflector is bent around each bulb so that helps. Fixture has a splash shield and fans - both are good things. I would definitely purchase new and better bulbs right off the bat - the ones they come with are not of great quality. Hope this helps
