I moved everything from my old 26g bow to a 40 breeder What’s a good height to hang my black box over the tank. Old tank was around 12” blues 100% and whites around 5-10
I think I'm running my 165 watt MarsAqua about 14" over my standard 20 gallon tank. I run the blues at 100% and the whites at about 50%. MIxed reef. (sps, LPS, softies) HTH. GL.
