metal halide lighting

[coralreefer]

Hi,
I am an intermediate experienced reefer, and I am downsizing my tank from a 75 gallon to a 46. It is not standard, its a tall one. I just bought a 150 watt metal halide fixture for the tank, and I plan on keeping clams and all corals. Is this a good light for the tank? sufficient?
thanks for the help in advance

i'm no expert on mh but i would say go with a 250. or the 150 with some supplemental lighting
