We just bought a 12 year old home that has a salt water pool and a Pool Pilot Digital system. I want to learn as much as I can. Forgive the novice question but the water is very soft and smooth but it seems as if people's fingers wrinkle very quick when swimming. Does this mean anything? I know it sounds strange but we have never had a pool before. I know it is at 100% purify right now. Thanks so much!!
