What it does for your water
The Diamond Crystal 40 lb Potassium Chloride Softener Pellets is softener salt in potassium chloride pellets form, 40 lb per bag, 99.6% pure.
Potassium chloride replaces sodium chloride for households limiting sodium; it costs more, and makers often call for a higher salt setting with it.
Refill before it runs low and don't pack the tank to the brim in a humid room, which encourages bridging.
