Probably a dumb question; but my mind thinks up these crazy ideas while I sleep - or when I am in the shower.
Follow the logic if you dare. For centuries people have added salt to water to soften it. You can still buy bath salts. I have a water softener at my house that uses salt to condition the water. Salt makes water feel slick and soft.
If the above is true, could I throw some salt in my pool and lower the CH, or is it totally unrelated?
