Ian, how deep is your tank? and how far is the T5 fixture from the water line? Do you think the 12x 54w fixture will work on a 30" deep x 30" width?

Perry, well, I'm not sure about the 30" tall part. I am getting good par at the bottom of my tank but my tank is only 20" tall. It will do the full 30" width spread fine.
