Well, I would be lighting a 18" X 18" X 24" cube tank . I have a 250W x2 PFO ballast right now and a 175w (something).. I didn't want to have the huge 2x PFO ballast hanging around the tank for no reason. I thought the 175w might give me enough lighting but I am not so sure.
I was going to do the following;
55w CF atinic
175w 10K
55w (unknown)
Any other configurations people think would be better? T5's are an interesting prospect but I don't think they will span well over 18", I looked at the bulb sizes, they are 24" min., I think.
