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
