MH for a 72 bow?

So i have 4x54w T5s over my tank right now, but the light is dying. So I figured maybe Id switch to MH. I was thinking of getting a dual ballast and run 2 lights. I keep mostly softies in the tank but do have a carpet at the bottom that doing weell under the t5s. Its a 72 gallon bow front. 48" long. Think 2 150Ws would be enough? Or 175w? 250w? Im guessing 2 70Ws wouldnt cut it. I want to go with an electronic ballast and use DE 20k or 14k bulbs
