Need input on lighting setup

[neenish]

I need some input on this lighting setup.
I have a 150g (48" L x 24" T x 30" W) tank. I want to use dual 400w MH using XM 20k bulbs as the main lighting source. I also have a spare dual 175w MH 10k Ushios that I would like to use in the canopy. Can I mount the 400w closer to the front of the tank and then the 175w towards the back of the tank (where the rocks would let some corals be closer to the water's surface). I also have 2 NO flourescent bulbs that I can use as well. Is this over kill for my tank? I'm going to keep LPS, softies, zoo's and ricordias, and slowly add SPS. Right now I have everything in my 55g under the 175w. Any input would be appreciated.
TIA
Brian

Great tank dimensions! As long as you have a way to control the heat you will be just fine. With 400's you can use less rock and place things lower in the tank. Be sure to acclimate your corals to the 400's slowly.

Hey Neenish,
Just remember that the electricity bill might kill you also here in S. Cal.
There is actually someone here in Riverside area that makes reflectors to mount two bulbs next to each other.
