My parameters are good no aggressive fish in the tank. All other corals are good.Need more info on your parameters and what kind of fish.
But if this is happing overnight we most likely talking about a large swing if some sort on your parameters.
No aggressive fish this colony have. Even in the tank for a year now.Looks weird to be honest,
What fish do you have? Any angels,file fish,butterfly’s ???
If not fish I’d be looking for a crab
Hermit crabs, snails for invertsIt’s just that damage like that is strange,it’s in a random spot on the coral and “to me” looks like it’s being picked at.
Any Crab’s in the system??
Carbon was changed during the last water change, not running gfo for two weeks now.Any fresh carbon or po4 absorbing media added recently?
That's my plan for today.I would say RTN as well. Best to frag as soon as you can.
What causes RTN?I would say RTN as well. Best to frag as soon as you can.

Thanks for the help. The rest of the tank seem to be happy!I was just thinking you may have had your levels swing too much and kicked off the RTN
RTN is generally caused by a sharp swing in water chemistry....ie KH,PO4 ect
This stresses the coral and causes the rtn it also can sometimes be bacterial
