Either sodium chloride or potassium chloride is fine - either will work fine as a brine solution for "regenerating" the resin tank. Either will result in the water hardness being driven down to 0 grains per gallon. Typically, the amount used per regeneration is a bit less with sodium chloride. If the used brine solution is dumped in a flower bed or near grass, potassium chloride would be a better choice. Potassium chloride is about 5x the cost of sodium chloride.
