A water softener removes the hardness minerals, calcium and magnesium, from your water. When water with these hardness minerals passes through the water softener, the calcium and magnesium ions are attracted to resin beads inside the softener. In turn, the resin beads release sodium ions.
Salt is used to recharge the resin beads once they are saturated with magnesium and calcium.

This formula improves the regeneration efficiency of your softener resin and prevents the build-up of hardness minerals in the valves and screens in the softener. Because Rock Salt is mined from a dome contained in a rock, it will contain a small percentage of impurities. These minerals may build up in your brine tank and will require periodic brine tank clean-outs to remove sediment. Because solar salt is produced in open ponds, some impurities from the environment get in the salt.
