Didn't have time to take a pic, but basically the heads of some of my long time palys and zoas are closing up, morphing into some weird shape, then actually falling off their base and everything melts. I've also had 2 shrimp die in the past 2 days. Only thing I've changed is adding live phyto to the tank. There area few of what I believe to be hydroids in the tank as well. Parameters and everything are all fine. I've stopped dosing zeovit coral snow from once a day to once a week.
