2 x 400 watt halides is plenty of light over a 150. the trouble is you are going to have to position corals very strategically. lower light stuff in the very middle and outer edges, and sps and such directly under the lamps.
i would use 20k lamps in those fixtures and skip any supplemental lighting.
