| How high should lights be?
I have a 175 watt 1100k MH over a 28 gallon all glass tank. How high should the light be above the tank? I have a few sps, leathers, starpolyps, clove polyps and zoas. everything but the leather and the pocillipora are growing and doing great. all parameters are perfect I have the light 18 inches above the tank now. is that to high? |
