[ccamaleon]

ok guy's i just buy'it a coralife 175 watt electronic metal halide pendant lighting fixture whit a automatic brightening and dimming control simulating natural sunrise and sunset. i pay $250 it got a 10,000k light bulb plus i got in the same 75 gal a 36 inch single lamp 96 watt 50/50". my question is this i can put hard coral's and clams?????:notsure:

metal halide will cover a 2 X 2 area, i think you need another MH to equal lighting throughout.

I don't think it is enough. What size tank is it for?
For my 75 gallon I am getting 2x250 watt MH and 4x55watt pc. With that I should be able to SPS.
BTW if you want to build it yourself you can do it for a lot less.
For the lights we are building it is only going to cost $300
