I love my hot tub but about 3 months ago I started getting very itchy rashes and could only pin it on the chemicals in the hot tub. I continued using the hot tub even though I knew I’d pay later! I started looking for alternative chemicals for it and came across EZ Spa Total Care. I stopped using the hot tub for about a week to let my skin heal. Drained my hot tub, cleaned the filter, I normally do my hot tub water change every eight weeks, filled it up and rather than the normal chems I added before I used the EZ Spa Total Care per instructions and added Chlorine (sanitizer). Like magic, no rash, no itch, no runs, no drips, no errors! Hope it stays that way!!!
