Mold due to moisture

I really don't feel like doing that. I think I'll just skip my pool. I don't want my kids to thank me for it with illnesses someday.

that is complete nonsense. There are good solutions, otherwise every swimming pool in the world would have mold and it simply does not. If I were you, I would visit a good trade fair and get proper advice, then you can still decide, but I simply cannot imagine that every pool in the world has mold
