Looks contracted. These corals come back from the ashes. Par seems fine. What's your PO4? Did you have any recent swings?

Never test PO4, tank 8months old. Alk hovers around 8.3-8.6. Yesterday test 8.5.

What can i do to save it?

Doubt a PO4 issue with rest of corals looking great. Any chance some salt creep landed on it and burned the tissue? Should recover with good parameters. Is it progressing?

Couple of things I would suggest- remove away from sand. They don’t like sand sitting on them. Do check if the cleaner shrimp is taking a bite out of it.

Once they start to go south, hard to stop it. It will more than likely pass. I would save the skeleton though, they have been know to sprout babies.
