I recently bought this coral (its my first) about 4 weeks ago. About 5 days ago I noticed a couple polyps looked like they were dying. My calcium is 460, alk is 9dKH. Is this a disease? I dipped using Coral RX before putting it in my tank. As you can see in the picture, where the polyps were in front, it is turning white and hard. Any advice would be great. Thanks.
