I would appreciate some guidance as to what type of flourescent bulb I should purchase to replace the original 40w 48" T12 (GE) bulb that came with my 72 gallon bow front tank (with a one bulb hood). I asked at my LFS for a comparably bright bulb, that would best enhance the appearance of my freshwater fish (red parrots, spotted puffers, clown loaches, etc.), and they suggested I get a "Reef Sun 50/50" bulb, since it would be the brightest for my tank. (My tank does not have live plants.) When I tried that bulb, it clearly did not light up my tank as well as my original bulb - the tank appeared much dimmer and the colors of my fish were less enhanced. Hence, I would appreciate your advice as to what type (and brand) of bulb would be best suited for my needs (freshwater/no plants) and interests (brightest/color enhancing).
Also, can you tell me if it should make a difference if I would replace a T12 bulb with a T8 bulb?
thanks for your help.
