MH light dilemma

[yuandaokia]

I'm getting a marine tank from a fellow reefer soon. Its size is 3X2X2. The tank will be housing LPS, SPS various fishes and invertebrates and tridacnid clams.

The lighting system I'm looking for will be MH plus 2 T5 lights that are on the hood.

The question I would like to ask is would 2x150 watt or 1 x250 or 2x250 be the best for the tank? Im afraid 2x150watt the light would be insufficient for the SPS and the clam and im afraid 2x250 the light would be too intense and "burn" some of the corals. Yet a single 250w mh would not be able to fully light up the ends of the tank.

I'm hoping 2x150w with the addition of the 2 T5s would be sufficient for the tank though. Anybody willing to share their views?

150MH on SPS will not be enough. they will bleached

if u r keeping LPS softies, then 2 x 150 w for ur 3ft maybe. with supplement of T5

just my 2 cents..
