Dan, I think I have a pearlberry in the center of my tank under a 8x54w ATI PM which is roughly 9 inches above the water line. I have it next to my ORA blue tort and roughly in the same zone is that green ora coral and all three are showing signs of burnt tips and and a little stn at the base of the green ora. I am thinking some of my params are out of whack and I will check it tonight. As far as light demands, is the PB and the Blue tort a highlight/highflow coral? Or should I move it lower, I burned the crap out of my green slimer at the same spot.
Thanks
Chris
