    In my opinion that depends on what is where for coral in the tank. The main factor is probably coral placement, that is a fairly deep tank, so you will have to find a balance between enough light at the bottom and not too much at the highest point that you have coral.

    I run 2 150watt Mh and have sps in all spots of my tank and they do very well. I did just recently upgrade my lights to include 4 t5 bulbs but even before the lights I had did wonderful

    I think about 8-12" from the top of the water is about average. I think on DFS divers den they actually tell you what color bulb and how far from the water the light is held for each specific coral. That may give you some reference.
