And, if so, what causes it?

It sounds like your daughter may NOT have folliculitis; the incubation period is longer than than that. However, chlorine is NOT an allergen.

Period. End of story.

We dealt with this at great length, earlier this year. What finally put it to bed was discovering that dermatologists still routinely use an old treatment, "bleach baths" with 50 - 100 ppm of chlorine, to treat a wide variety of skin conditions!

Unfortunately, the hodge podge voodoo blended shocks, like the one you have (see below) DO sometimes contain chemicals that are known allergens and irritants.

Also, though sodium bromide -- and bromine generated from sodium bromide -- is not an allergen so far as we know, bromine in solid form is bound to DHM -- dimethyl hydantoin -- which can be a SEVERE irritant.

That means, 42% potential problems!

Give that stuff away. Or flush it down the toilet, a little at a time, but ONLY if you are on sewers. Do NOT dump a bunch in septic tank.

My daughter is mostly recovered from her rash but my wife has (not unreasonably) vetoed any further swimming until I figure out what happened. She also was talking to someone who suggested dropping chlorine and using bromine. I don't know much about that but what little I've read makes me not want to do it. Plus, it would mean that the chlorine problem defeated me.
The tabs are fine.

I looked at your chart -- 4,000 gallons doesn't cost that much. If it's not a big deal for you, drain and refill it. But NOT till you are ready to follow a plan. Read the Intex recipe in this section of the forum, and be ready to follow it BEFORE you drain and refill.
