Made with 99.1% pure potassium chloride, these crystals are NSF-certified and designed to keep your unit running smoothly with low insoluble content.
: It is generally safe to mix potassium chloride with existing salt in your tank, though you may not see the full "low-sodium" benefits until the old salt is completely cycled out.
: Since potassium chloride is less efficient than salt, some manufacturers (like GE Appliances ) recommend increasing your softener's hardness setting by about 20% to ensure effective regeneration.
