DD will be swimming for the first time since pump start after school today, and I am worried about the site coming off. Would like to hear from others whether this has ever been an issue. The pool that she is going to, I believe has 'salt' water, not sure if it would have chlorine as well. She is using the inset II today. Will the chlorine/salt from the pool cause the site to come off? At times, even without swimming, we find the adhesive peels up around the edges. They seem to still stay on but just looks like it's about to come off. I have heard the IV3000 is not useful in the pool. Any tips?
