I don't have much else to lose l'm down to a few spa frags now lol. I syphoned out my sand while I did a 50 gallon water change. Matched all parameters in the tank before I did the change.

I checked it out this morning and everything looked ok. First morning I didn't find anything dead. Fingers crossed!
