I am a new member on your site,although I have been using it for awhile now to get info.I wanted to thank everyone for the useful info I have found here.Now ,my problem:We purchased a 2013 Hot Springs Flair in Dec 2012.Since then,I have decontaminated it once according to the steps I have found on this site,then started following your dichlor/bleach method.I now realize that we have had a bad case of that nasty little bacteria due to not using enough sanitizer.They told us that all we needed was 1/2 tsp.of dichlor before a soak and we were "good to go",found out the hard way that was not the case,hence the decontamination.My water now is crystal clear,everything is where it should be,according to my Taylor k-2006 test kit,but I am still getting patches of little bumps that show up the next morning after a soak,even though I shower after getting out of the spa.The bumps appear on the back of my calves and sometimes around my elbows and under my forearms.They are extremely itchy,but not a rash.I am the only one affected by this, no one else is having any problems.Just wondering if anyone has any thoughts on what could be causing this?We soak for 30 minutes,water temp is 100, PH=7.8, TA=60ppm, CH=120ppm, CYA=25ppm, Borate=50ppm, FC=3ppm, CC=.5ppm. Any suggestions would help,as I am at my wits end and don't know what to try anymore.
