I have a hammer coral and the base is slowly turning white. Perimeters all fine but it’s getting worse. Thinking about doing a dip on it again but I dipped it when I got it 6 months ago. I don’t see anything on it so I’m looking for some constructive feedback on it and maybe someone has had this happen to them and has a remedy for it. Thx, first pic is a week ago and the other is now
