How many T5's

[geno7]

I've all ways used halides to light my reef tanks and I am building a new 75 gal all-glass tank. The many threads on Reef Central about T5's has sparked my interest. How many T5's would I need to light this tank? My original idea was to use 1 250watt halide that I all ready have and purchase another to run along side of this one. This will no doubt generate a good bit of heat. I like the idea of having a lighting source that would reduce this problem and maybe save a little on my power bill. Please include the mix of suggested bulbs. Thanks
