To be fair, there was a batch many years ago with stupid high alk that killed a lot of tanks, but it was widespread and lots of info on it. But it killed everything, fish, corals, etc.
In this case, I doubt it was the salt.

I also buy a years supply of IO every boxing day at Big Als (9 buckets). I go through a bucket every 6 weeks.

Had no problems with any of my 2013 buckets and I'm on bucket number 3 from this past boxing day 2014 with no problems so far.

I would seriously look at possible sources of contamination or maybe a drastic change in salinity due to a uncalibrated measurement tool.
