Hey guys. I currently have a 12g Nano Cube DX setup which has 2 24 watt PC lights over it, and I'm about to move everything into a 25g long tank which will have 1 175 watt halide over it. Both of the tanks are about the same depth (12") So my question is how high should I start the fixture above my tank to avoid burning all of my corals?

what corals are you moving?.....you could probably start out with the halide around 14-16" for a few days....(3-4min)....the move it down to 12" after another 3-4 days.....after that maybe another 2" where it is 10" above the surface....of course this is all depending on the type of reflector and actual setup you planning
