It's a long known fact that chlorine cannot be good not just for our kids but for everyone, it's chemical that's not "compatible" with our body. Unfortunately public pools don't have too many alternatives, they could have good filtering systems but this is not enough. Quitting on chemicals means exposing our kids to risks of infection or contamination. I am still waiting for the ultimate natural solution, until then I'll just use my home pool, it's not that big but I do have a intex filter that keeps it clean whenever I need it.
