Why not to use io salt

It's not just the big three that can nuke a tank. I lost a whole bunch of SPS to a bucket of reef salt(not IO or RC) that was deficient in Potassium.

Since the majority of the cost of salt mix is freight one must wonder how they can sell it so cheap. What quality are the chems used?

It's not correct to assume that just because no one else complained that it's not the salt. It's also not correct to assume that just because part of a batch is ok that the whole batch will be ok.

What did you end up switching to after all those years of IO?
