Should I trim this chalice?

[RobertK]

This chalice coral is about 6" in diameter. It has been healthy and growing for the last 2 years. In the last 2 weeks there has been some tissue loss around its margins. I think this was caused by a dosing pump problem - my calcium dosing pump failed and Ca got too low and alk got too high; it was probably like that for a week or two before I realized and corrected it. My other chalice is fine. Should I get the bone cutters out and trim off the exposed portions of skeleton or should I just leave it alone? TIA.

Leave it alone unless you want to frag it into a smaller chalice. Are the edges overgrown the disc its on? Have they been buried in the sand at all?

It is not on a disk and there is no sand in the tank. It is glued to a rock and sits a few inches off the floor of the tank.

I would leave it. Unless its been receeding for a while and there is algae already growing on the bone, then you might want to scrub it or trim it.
Receeding chalices have usually always made a full recovery in my tank unless the above mentioned issue comes into play.

In case you end up fragging it, a dremel with a diamond blade cuts through it like it is butter leaving nice clean cuts. I’ve done it with my at least half a dozen times.
