Matt & texastodd, Don't you guys think that 2 x 250w with t5 is a little over kill. With a t5ho setup alone you can cook you acros if your not careful with acclimation. I'm not trying to argue I'm just thinking holy macrel that's a lot of light. I do want good light over my tank but what your suggesting is around $800 compared to $350 for 1 400w setup. There is someone here on maast who says they have a 2x250w setup with lumenarc for sale, pm'ed him no response yet.
