I would consider 6x54w t5 retro with icecap reflectors and icecap ballasts. I would use ati bulbs with maybe a ge 65k bulb. I went from a 400w reeflux to this set-up and love it. I love the fact that you can play with the spectrum (target certain bulbs over certain corals). For example, I got my A. lovelli to change color from sky blue throughout, to sky blue tips and a red base (using an ati procolor bulb). Bulbs are cheaper. Bulbs are way more efficent, i save about 30 bucks a month on power. Plus the bulbs will not heat the room up as bad a MH, which would make the chiller work harder. The only major complaint about t5's is that they do not produce the shimmer that MH do. Not that I'm a hardcore t5 guy but i think its an option that you must consider. FYI, I have a stone garden taking up all 18 inches of depth in the 75g.
