Why not to use io salt

Fish are happy. Corals look like they've had an abrasive pad applied to them liberally. It's really odd, not your regular RTN event. A lot of them kept polyps, but lost all surrounding tissue. All mollusk and echinoderms were pretty much dead withing a couple hours.

Maybe a better title for this thread would have been "I did a normal water change and wiped out my tank. I am speculating that the salt was the culprit - Or evil voodoo magic. 50/50"

But nobody following this thread will ever know for sure without a test of the salt will they?
I will continue to use IO salt as nothing was conclusive proving bad salt was the "issue" here. I'll be doing a WC within a couple of days and we will see what happens if anything.
