I need some fast advise on how to stop my Hollywood stunner chalice coral from continuing to die. I noticed over the weekend there was a hole in the middle of my coral and over the past few days it's gotten worse. I don't know if I should dip it or move it or leave it or what. Someone that has a good idea of what is happening and how to remedy the situation would be great. All parameters are in check phosphates are a little higher than normal at .10 I can tell that I am nearing the life of my fgo. So I'll be adding new gfo during my next water change. Otherwise all other parameters are normal.
