I hope your corals recover! I'm sorry to hear about the problems.

I suspect that at least one of the solutions is a mix of various trace elements. I'd be cautious with the trace elements solutions. It'd be strange if the calcium and alkalinity solutions were causing trouble, but certainly not impossible.
