250 sounds like alot of power over a 12, i have a 175 on a 25 and its bright and heats the water up a bit. 250 sounds like it would boil the water.

I moded my 12g NC a few years ago to put a 70w mh in the canopy, I added a couple extra fans to help with cooling, however my biggest problem was evapouration.

interesting... I think i'll end up getting the 250, just because I dont want to by MH then have to resell it... just have to experiment with the hight i suppose. I have ATO so evap shouldn't be an issue.
