Coral Dying Help!

[NanoMan16]

Ok woke up 3 days ago and noticed all my coral was closed up. Didn’t think much of it at first *mistake*. Next day same and started to worry. Tested water with Red Sea test kits all looked ok nothing to crazy. Today my Duncan’s green skin around base is starting to peel away showing the white skeleton. My Acan frag is dead bleach white. My toadstool leather is a white solid lump so dead. Zoa’s and GSP are closed with a brown almost red slime over the opening. Help I have know idea what is going on. I’ve had a tank crash but usually something was wrong. Plus my fish are fat and happy.

IDK if anyone else has had issues with too much copper from the additive but i havent dont much research on aquavitro fuel, aquavitro in general are not bad additives, might want to search a few threads or start a new one asking if other have had issue with copper + aquavitro fuel, sorry im not too much help on that front

If you do suspect copper, use cuprisorb and activated carbon to take out the rest of it

I use chemipure already is that sufficient?

Just retested my water…
Everything is the same except Ammonia is now 1.2 that might be the problem also. Odd that it showed 0.5 earlier.

Not only is ammonia high, but you may be getting false reading. You mentioned you but water from LFS. Test that water before using it for Ammonia-ph-nitrate and Phosphate
Moderate light and water flow and assure there are no little black bugs on any of your corals.

I do test it every time and always 0 everything, PH 8.2, Alk 7, calc 460, PO4 0 TDS 0. And no black bugs that I can see. Only ampipods on rocks…
