Duncan tissue recession - Yellow ring around dead area; bugs; white egg looking things

[NomadicReefer2]

I recently began noticing an issue with my Duncan coral. It has been a little more closed up than normal but not much. on the side skeleton area of the duncan there is a bit of tissue recession. There is a open patch on the upper section that is surrounded by a yellow 'rim'. Where the skeleton is exposed there appears to be some tiny little bugs. Where the tissue used to be on the bottom section there is some opaque white ripply looking thing. If anyone has a clue whats going on please lmk.

My parameters are:
PH: 7.9
ALK: 11.4 dKH (bit higher than normal(
CAL: 443
mag: 1300
phosphate: 45 ppb

Lower your phosphates and alk it looks just ticked off imo. I shoot for 10-19 PPB for phosphates. And 8-9 DKH for alk.

Hard to say for sure, but the "ripply looking thing" might be mesenterial filaments...

Thank you for the input. My nitrates must have risen causing the alk to not be absorbed as much and rise. I went ahead and ordered a new ro filter so i can get some better water running.

'Mesenterial Filaments' is a new reefing term for my vocabulary. I think you are right about that. Im happy its not some sort of egg.
