Euphyllia paraglabrescens

Hi!

I noticed lately that my euphyllia paraglabrescens is kind of shrivelled up. Or at least not fully expanded as it used to be.
There was an incident lately that I accidentally tested Ca with the wrong fluid, which gave me a false reading of too low calcium. I dosed some Ca and realised my mistake afterwards.
I re-tested and calcium was over 500. Probably around 600. Paniked and did immediately a 20% water change and got the calcium down to 500.
i thought that 500 was not too much and I would let it come down naturally in a few days.
All was fine. None of the inhabitants looked affected. Inhabitats are:
3 chromis fish
1 small Acan Lord colony
1 Goniastrea LPS
5 small SPS frags
2 small zoo colonies
1 Euphyllia frogspawn
and
1 Euphyllia paraglabrescens

The only coral that seemed to be affected is the paraglabrescens. It stays kind of half-extended, and never extending to its full size. It used to have this closing up / down but that was expected due to the time of tha day / night.
After that calcium incident it stays mostly half-opened, doing some weird things with its tentacles. As if they are frizzy. Also it will not actively eat. Even if I "spray" some mysis or tiny chopped pieces of clam over it tentacles. It will catch the pieces but eventually will let the current sweep them away.

Does anyone know if this kind of euphyllia is sensitive to calcium swings?
If not what else could it be?

I mean ALL other corals are looking really really good! Actually they look fantastic.

torch is crankier, for sure, and doesn't like to be too near anything else. I'd try to get that calcium closer to 420. Just let it slowly decline, and I doubt it will damage the coral, just put it out of sorts for a while.
