Tank is crashing :(

Did you start with live rock or dead rock. I don't think it should be releasing that kind of odour from the sand bed. If I had to guess I would think there is some sort of contaminant(s) in your water.

I started with both. I used the old rock from my old tank and added new dead rock. It's getting to the point that all my corals are dead and if it happens, I'll siphon out the sanded and do a massive water change and start over
