That doesn't change what I said. Frequently, most chlorinated pools have other contaminants that are serious irritants. It's POSSIBLE your daughter is truly chlorine sensitive, but that condition is usually very, very rare. With a properly balanced and maintained chlorine pool (as per our BBB method) such sensitivity usually vanishes. I suspect, if she's OK in low-chlorine pools, that it's the chemistry, not the chlorine level. Combined Chloramines are VERY irritating to skin and eyes, which is why we like them to be at zero.

But a salt-water pool, is STILL a chlorine pool. There are alternative sanitizers, like Bacquacil and Bromine, but they are difficult and expensive to maintain and frequently and easily get algae.
