Favia is dying . What is it?

Hi!
The tissue of favia dies from the edge to the center. There is already half of the coral left. What could it be? Slime is spreading at the edge as eating of the coral (or it just seems to me)

Hey Mizu,

Do you have the current parameters for your tank?
Salinity, Alkalinity, Calcium, Nitrate, Phosphate.

Those will help someone who may be a favia expert to get you on your way to recovering this beauty of a colony!
