Hello everyone, I have run into a major issue with my chalices peeling and no one seems to have an answer for why this is happening. All the chalices I have had been doing incredibly well for a year or more but recently several of my chalices have started getting lighter in colour with mouths wide open and then the flesh peels right off (all different types of chalices). I have kept chalices for many years and have never had this issue. My water chemistry is always stable and I test frequently. Mag is 1450, Calcium 430, Alk 8. I haven't changed anything in the tank. All my other corals are doing well including favias and acans and mushrooms, as well as acros so I don't understand why the chalices. I know there are many experts here and I would really appreciate your help. I also ran an ICP test and here are the results if anyone can help determine where the problem is.
