Which water to fill with - softened or reg

[cwstnsko]

normally Calcium rises slowly due to the fact that calcium does not evaporate and the make-up water contains calcium. Soft water for make-up water is a good idea to minimize the creep, but can drive your salt level up.

I tested a neighbor's pool for salt the other day and he was at 800ppm merely by using soft water for make-up. He seems to get about 800 gallons per re-charge on his softener
