Dying Coral Help

[Chris’s fish]

Hello all,
First of all I’m not sure if those is the right forum to post this, but here I go.

I have a chalice coral which has always grown super fast for me and has always been healthy. However recently it has been getting these white spots where it appears the tissue is dead. More and more spots are appearing and I don’t know why. Can someone help me figure out why this is happening and what I can do to stop it/ fix it. Here are some picture. Thanks for the help

I can not say that I know what that is. But i f it was me, I think I would pull it out if possible and give it a coral dip.

It’s does not seem like that is helping. Do you have any other suggestions? And it doesn’t seem like a pest is doing it

I am sorry, I don't. But hopefully someone else with more experience will chime in.
