Emergency, need help with torch coral

[NewFisher18]

My torch coral I recently noticed has been looking really rough. I don’t know what’s wrong. When I bought it it’s tissue had been receding(I didn’t know what to look for at time) but now I can see the base and some white stuff on top. Idk what’s wrong. Alk is 9 I raised phos to .2 to battle Dino’s which r gone. Everything else seems to be in range with nitrates around 8. It looks like the corals tentacles are peeling off please help. Srry for the dirty tank just scraped glass

What are your phosphates, calcium and alk?
Also, it has VERY little flesh band. Are you able to move it to a low flow area so I can regrow? It will take some time to grow though.

.2 phosphate is kind of high, did you raise it rapidly?

Do you have any other corals in your tank?

When making adjustments for your tank, make sure they are gradual and nothing sudden.
