Please help--snail died and then I made things even worse...

[sharuq1]

It isn't "foul" per se anymore it is just having a very high ammonia spike. My only guess is that it is being caused by:
-my 100% WC
-removal and subsequent wrecking the LR, which effectively removed my bio-filtration almost completely (there was some BR in there for 7 mo. so hopefully some bacteria colonised that, it is still in the tank)
-dying zoo polyps, but I am unsure which are dead and which just look bad so I have only removed the ones that I know for sure are dead
-fish in the tank in "new" water that has not been cycled

Some corals look unaffected, some died, some are very damaged....
