How deep is your tank? What corals do you want to keep? This will make a big difference in the amount and type of light recommended. Keep in mind, it is not a watts/gal
thing, its a penetration thing. If you are interested in anemones, clams and SPS
corals then MH
is a better choice. It will give you the best penetrating light for these highly light-dependant animals. www.aquatraders.com
has some pretty decent and inexspensive MH
combo fixtures. If you intend to only keep softies with some LPS
corals then CF
or T5 should be just fine. Bottom line...figure out what you want to keep and build lighting around that. Reef lighting is one of the most exspensive parts of a reef tank so you only want to do it once.
