ATI Powermodule Question

[Nuocmam]

Dunno if this is in right forum. How many inches over the tank do you guys running an ATI fixture have your fixture over the tank? I have a 6 lamp fixture with a 90G 48"x18x"24" LxWxH. Mostly sps. TIA.

My tank is 48x18x25 SPS dominated and i have my fixture 6-8" above. When i had it closer, my corals did not like it. I have sps and clams on the sandbed (well did, the clam was getting too big, so gave him away).

I have the 10bulb fixture over a 48x36x24 and im still trying to find the sweet spot. Some sps i cook on the sandbed while others do fine. im at 8" right now and looking to move up to 10"

On my 18" tall I am about 16" over the tank. That is for a mixture of LPS and SPS.
