You know, Alex, et al, I have said this before and was
corrected by people who I believe are more educated
than I in this arena, but the evidence is strong for
our case. Let me ask another question to Alex and
others who have been experiencing this.

Did you use an agro grade KCl off the shelf of a
hardware store or home center. That's what I used,
specifically Espoma brand. Once again I have not had
problems with shrimp death since switching to K2SO4. I
wonder if there is some toxin or metal in that mix
that could cause problems.
