Catalaphyllia just dying twice

[aumoenoav]

Im a bit clueless why two of my Catalaphyllia just died almost overnight. Both was on the edge of the aquarium, under moderate light and flow, but just got extremely sad and just shredding down to its skeleton.

The rest of the corals looks fine.

Attached an ICP printout I just took. Some results are a bit high, but nothing that should be grounds to mass dying?

ICP printouts are not helpful in the case of coral disease, pathogens. Elegance corals have major issues and are known to die randomly.
Hobbyists have been having issues with them for over 15 years. I just don't buy them.
