[Hot Tub Itch]

yours sounds like the dry skin effect some people get with the hot water and chemicals, have you tried lotion after getting out of the hot tub?

I'm trying to get up my courage to get in again this week, and that's something I will try. Seems to me I've done that, and maybe the itching was better, it's been a while. I know that last Wednesday night I definitely had a longer soak than normal, did not use lotion, and thought the itching was going to kill me. No rash or welts, etc, except from where I'd been scratching. Thanks for the advice! I'll post after I try it!

[Potassium Monopersulfate (Mps)]

They are both oxidizers, but are not the same. The active part of the potassium monopersulfate (aka peroxymonosulfate) is the HSO₅^- ion while with sodium persulfate (aka peroxydisulfate) it is the S₂O₈^2- ion. This is actually a minor component of MPS as it is sold, at around 3%, and is the contaminant most closely associated with skin irritation. So while it is an oxidizer one could use, it is more likely to irritate than MPS itself.

I have just recently been getting itchy after using my spa. The itch (no rash, mind you) occurs about 12 hours after getting out of the spa (and showering) and lasts 24+ hours, and is very intense. My husband, son and my friend that I soak most often with are not affected. It's mostly on the backs of my legs, and the insides of my elbows and knees. Not so much where my swimsuit covers. We are trying to figure out if it's a pH issue (but our test kit says about 7.6) or if I'm sensitive to the stuff in the MPS. We use chlorine and try to keep the levels between 2-5 ppm, have a Nature 2, and the spa has an ozonator (not sure if it's actually producing ozone). It's a 1996 Sundance Optima, and I had no issues the first 6 months that we had it (bought it refurbished in March 2010). I don't have the itch the first couple of uses after a water change, and the itch is worse if I stay in the tub longer. Help if you can please! I'm afraid to get back in the water!

[Hot Tub Itch]

Hi this is my first time on this site. I think iv got the dreaded hot tub itch. had my hot tub since may 07, no probs till sept 07 when i developed very itchy rash, iv been trying to sort since then so driving me crazy. iv blamed washing powder etc.. in fact everything but my beloved hot tub, but after going in sat night, sunday i was covered again in red blotchy,spots, n back to itching. my doctor is in the process of arranging patch tests for me. I currently use bromine in the tub but iv just been reading up on the "Natural" eco products. does anyone use these, and can advise me if they work. I cant bear the thought of watching everyone else in there and not me.

I know it's been a long time since your original post, but I wonder what you found out? I have the same problem - got spa in March 2010, started having itchy episodes in October. Nothing about the spa has changed. We use chlorine and non-chlorine shock. I don't have a rash at all, just terrible itching, mostly back of legs, inside of elbows and knees. It starts about 12 hours after I get out of the spa, lasts 24+ hours, then I'm fine. Would love to know what you found out. Nobody else that uses the spa seems to be affected...
