Hi everyone, back for the first time this year. My pool is fine but last year we went to the grandparents for a month up in Maine and my kids got the wickedest rash anywhere their bathing suits touched. The boys in the nether regions (terribly painful) and the girls sort of all over. They had only a basic test kit, have had the pool for years and have only used the tabs. FC and PH were normal. What could have caused the rashing??? It was pretty bad, bad enough to make them not want to swim and I have got to get it figured out before we can swim this year. Dont want that to happen again. So again, what could be the cause??? What should I look for?? I am bringing my good test kit up with us this year so I can test for everything but wont have good access to the school while I am there. Any help in advance would be appreciated.
