Thanks guys. I think I'm going to go with that fixture. I would like to get a better one, but it will give me more then twice the watts of my current fixture without putting me in the red too far. There was one on aquatraders.com that I liked, but they were out of stock... anyway, I really appreciate you guys helping me figure this out.
