Hey so I recently got this duncan coral (first coral) from the LFS, I asked then to QT him for me and when got home did a basic pest check, removed the frag and glued him into the display tank. The question is he's closed up most of the day but when I get home from work he tends to open up. The reason I believe is because my lights are programmed to lower until they shut off. When the lights on on full throughout the day he isn't open and when they lower he does. Anyone have any recommendations to what I should keep my lights at? I currently have 1 ai prime 16hd. Will get another soon.
