After waiting a week ...since adding the MPS and maintaining the Bromine at 3ppm (with ozonator) I went in........ and within hours... had a rash.
I took the easy way out this time... I already had Baqua spa chemicals.... so I drained, cleaned and started up with Baqua spa. I have never had any real problems with it. Allergy is gone !
I would like to find out which component (MPS, Bromine) is causing the problem.... I might have to go to an allergist to isolate the allergy.
I'll keep everyone posted...
