Pocillopora STN

I just noticed it this morning, my montis and millis are fine though. Its a newish tank so its probably been having swings, but they haven't show on my tests. All the polyps left and all the polyps on my other corals are full extension.

The last two tests have been:

Calcium 320, 315
ALK 9.3, 10
pH 8.28, 8.18
Salinity 1.026

I test every 6 days, so I will be testing again tonight.

Some other info, this is in my Elos MINI, 20 gallon tank, it ends up right around 22 gal of water total with the sump. I run GFO and Carbon in the sump. Skimmer. AI Sol LEDs at 30% (they have been under these for 10 days now, a monti bleached but has since recovered and everything else was fine). Flow is the return pump and an MP10 constant at around 65%.

I would prefer not to frag it, but I can if I have to. If I leave it, will it grow back over the dead part? Or will it continue going?

that calcium looks low. i have mine in range of 420-440

Yeah, after I got that reading, I dosed around 6mL of my 2 part, which was the max recommended dosage.

I went ahead and fragged the base of the coral, as it had moved another 1/16" over the course of a couple hours. It was all open again about 15 min later, so hopefully that stops it. My other corals still look fine, so I'll be keeping and eye on them.
