I am new to the saltwater world. I got this brain coral 3 months ago. It has been doing great. I noticed it wasn't opening like normal. A week ago I noticed the bottom edges was becoming stony but it was the same color as the coral so I thought it was normal. Two days ago it never "œblew up". Just stayed like the picture. I checked my water and the nitrate was 20 so I did a 20% water change and added a nitrate removal sponge to my filter per the local pet store. Today the edges are looking more stony and lifted and it has white wavy lines in the pink part close to the mouth. I am worried please help.
