I've been having problems lately with my corals not opening all the way.. The only one who seems to open completely is the frogspawn, the rest such as leathers, zoo's and mostly soft corals aren't opening all the way. They open, just the polyps aren't extending, and the xenia's look dead, but they still come out. This hasn't always happened, and I was thinking it was the lighting, but if the frogspawn is opening the most, I'm not sure that's the problem. Any suggestions? Temp is around 82, which is a little high, but it's always been that high, and my corals haven't always looked this way. The PH is always between 7.8-8.2, nitrates stay between 10-20, salinity is 1.025. I'm running a 4 bulb power compact light, 2 blue, 2 white.
