Reason I bring this up, I had 3 - 50 gallon bags of IO I had sitting in my shop for nearly a year and when I opened up one it was clumped together in large clumps. I broke it up as much as possible but used it mixed with salinity once and RC the next couple of times. I tested water before I put in my system and it tested OK.
This is something I just thought of.

My guess on why I didn't notice stray voltage is it just worked out that I would be working in the tank during those times when the heater wasn't on.

Smelly pockets in the sand indicate that either the sand was too deep and/or not vacuumed properly. This is why we recommend putting the rock on bare glass and not putting rock on top of sand because it can trap those pockets of detritus.
Hope everything goes well from here.
