I have a SWG and had my pool filled with my city tap water last year. Since then I have had a water softener installed in my house, and the line that goes to the auto pool fill uses the softened water. Also I use potassium chloride as the salt in my water softener, since my back sprinklers are on the same line. Will this small amount of softened water, (using potassium chloride) which is used to replace the lost water from my pool affect my SWG or not?
