I hope so. That was his thoughts. I thought for sure he would be lining up allergy tests, however he did not think that was it. I never tested positive for latex, metals etc etc, just pollen/dust allergies, none of which ever caused a rash like this. Never had an issue with chlorine or SW pools before, so it has to be that salt. I may never know what actually caused it but I sure hope we are on the right track with the salt additive being the suspect. It certainly all lines up pointing in that direction.
