I have also been noticing that the skeleton on my blastos and acans have been starting to become exposed, I think it could be them

+1 to Amphipods. Good clean up crew and free food for some of your fish too!

Missed this part... they don’t usually bother corals. I would guess that is a different issue, but anything is possible!
I would post some pics of your corals and parameters in the LPS category. Lots of good folks there who can help you nail it down.
