Sps corals

[Bill0181]

Anyone know what could cause an sps to start losing skin overnight? I put a birdnest in my tank yesterday acclimated properly and parameters are normal and today it is shedding it's skin and bleaching along with a cap and another nest I put in yesterday? Chalice in tank has been doing awesome for a year or so but any new sps just kicks the bucket quick all softies are thriving what could be the deal?

Alk was 9.8 so that was not an issue, even took water to lfs to make sure it wasn't my kits and it tested fine,

Had copper test done also and it was negative no visible color I'm doing a 50 percent water change with a different batch of salt to see if this resolves the issue
