Digitata dying

My digitata is suddenly dying. In the past two days the bottom parts are turning white. Is this because of montipora eating nudibranch? I can't see anything with my naked eyes. My water parameters are okay as far as amonia, nitrate and nitrate, zero or near zero. Other coral seems to be fine.

Anybody has some Potassium Permanganate? Is it too late to save it?
 
Is the water getting warm? You could clip off the good parts before they turn white, I guess.
 
What's the ca alk and mg at ?

I just order additional test kit for ca and alk. It was growing a couple new bumps/branches until base is turning white.

Water may be warmer because of summer time about 80-81 degree. Light is not the issue. I use LED, it's near top.
 
Everything I know says to frag it now and cut some margins above the necrosis.
You can the split the frags in different flows and lighting environments.

My own personal luck has been poor once the TN starts if I do nothing.
