    Most MH have 2 ft coverage so on a six ft tank you should be looking at a 3 bulb fixture unless you have everything centered in your tank as a 2 bulb unit will not give enough colour on the outside. You could put your less light demanding corals on the outside edges then it might be okay but a 3 bulb unit won't be that much more if you shop around. ;)

    I would get a 3 light unit for the reasons stated above.
