I'm 6 weeks into my FOWLR tank (29 gal tall) and I have decided that I really want to go into corals. I do not have sufficient lighting and due to space concerns above the tank I am concerned about going to Halide. I am thinking that either T5 or PCs are the way to go. I've seen some PC systems for sale on ---- for about 60 bucks ranging from 65 W to 130 W. Would this be sufficient for corals? Any advice appreciated.
