MH is a must now

[Saltysteve]

Well MH; it just has to come now
I am thinking of constructing my own hood to match the stand. The hood of course will be constructed to allow proper clearances etc for heating and mounting fans. My tank is 48 inches long, almost 50 gallons with a black 1.5 inch center support. I want to use one 400 watt 14 000k setup. Going to use polished aluminum or just paint white. What do you all think? Enough light for anything I want? SPS , Clams etc

Thanks
