I spent the big bucks on lighting when I started this hobby because I knew eventually I wanted corals that require very good lighting. I have a one piece light with five fans, 4 blue actinic lights ( I think 750wtt), 2 MH, and blue moon lights. The tank is a 72 gallon bow front with 30 gallon sump and refugium. My problem is that my rock is bleaching out. I took the advise of others on another thread I started about how my temperature was influenced by these light. I have been searching AA and researching on my own and I think my lights are too close to the water. I had cut down on the lighting to just 6-8 hours a day but I want to be able to run them the 12 hours recommended. I have not been using the MH at all. The light came with little legs to mount it on the edge of the tank. These legs are only about 5 inches. So I think my solution is to hang the lights from the ceiling at about 12 inches above the water. My Questions: Does that sound about right? How long does it take for the coraline to come back after bleaching? When can I find the hardware to change it to a ceiling hanging fixture? Could those of you with lights that hang post a picture so I can see how to go about this? I cannot find any pics. Thanks again for all your help
