Light for 29" tall?

I don't have any experience with lighting a tank of that size. But I'll throw some ideas out. If you are good with your hands, check out AH Supply . Depending on the type of setup you want & the type of plants you want to grow, you could go with either the 4 x 96 or 6 x 96 watt kits. Another option would be metal halides.

T5 lighting would also work very well. I have an Aquatinics Constellation 72" T5 over my 210 saltwater reef tank and love it. It will be converted to a freshwater planted tank shortly. The T5 can penetrate that depth.
