This guy is trying to sell this light pretty cheap.. It is a Zoo Med 24 in t-5 fixture. He wants 30$ for it. Zoo Med AquaSun T-5 HO Double Light Linear Fluorescent Hood at PETCO I have a 29G tank that measured 30L X 18H X 12W Will that produce an array of light that is sufficient for the tank? I would only want to grow basic corals.
