Water Softener Salt

Diamond Crystal® Water Softener Salt makes it easy for you to transform hard water to soft. 

When used in your water softener, our water softener salt helps remove minerals from your hard water, including iron, calcium, magnesium, and even barium. These hard water minerals are removed when water passes through resin beads in the water softener tank. Salt or potassium chloride is used to periodically recharge the resin beads so that they can continue to remove these minerals. After our softener salt helps remove hard water minerals, you have soft, bright towels and clothes, shiny dishes and longer pipe and appliance life.
