I don't know what to do. I have had my pool since I bought the home about 14 years ago. It was here when we moved in so I'm not real sure how old it is. When we opened it up this year it was fairly clean although it had quite a few spiders in it and what looked like white mucous in the pool. We got rid of all of it and set up our filter which is Dalomite. The pool is crystal clear and the levels seem to be fine.
However, every time my husband goes into the pool he gets this horrible rash along the inside of his thighs and stomach area. He tried changing the chlorine tablets to a different brand and changed the dalomite in the pool. Yesterday he went back in and by the evening he broke out in a horrible rash. We don't know what could be causing it but find it very upsetting as he enjoys being in the pool
