Finger leathers melting

I have 5 colonies of finger leather that simultaneously shrivelled up about 2 weeks ago. Ive had them about 8 months and they have always looked great. They are getting some diatom growth on them which i continuously blow off and now today ive noticed some fingers have fallen off and some parts appear to be disintegrating.

The only change in my tank was about 3 days before this all started. I fragged a large toadstool leather and started running carbon to help with the toadstool decay. My toadstools and all other corals have been looking great for about a week now though.

I recieved my ICP test which i will.attach below.

Any help appreciated!

I highly doubt it. Every colony reacted at the exact same time. Id think nudis would attack one first then spread to the rest. Also i havent added any new coral or rock in months

Im starting to think its really just from the toxins from fragging the leather. Ive changed the carbon twice and done 2 10% water changes so far which i will keep up with but im hoping its not too late. I cant do more than 10% at a time though because the tank is 800 gallons
