Saltwater ****es me off

I've checked the tank up and down and can't see any dead livestock. I can't find the nassasrius snails though, maybe they died in the sand? But again I wouldn't understand how because everything was perfect. I'm going to change 50% of the water and see what happens, if it doesn't help the tank is getting shut right down.

I live in Surrey, near Bear Creek Park.
The TDS today is at 9ppm. I have never seen it above 15.
So I agree with the former poster that mentioned something might be dead.
Whats your feeding schedule?
