Diamond Crystal Solar Naturals Water Softener Salt Crystals are made naturally with sun, wind, and time, resulting in typically 99.6% pure solar salt. These white, opaque crystals are recommended for use in all water softeners and help transform hard water into soft water by removing minerals during the regeneration cycle.

The solar salt crystals feature low insoluble content to minimize accumulation of tank residue, helping maintain your water softener's efficiency. By removing hard water minerals, this salt helps prevent scale buildup inside pipes, fixtures, and hot water heaters. It also extends the life of appliances like dishwashers and washing machines, reduces soap films and buildup in sinks and bathtubs, and eliminates mineral spots on dishes and glassware. The result is softer, brighter towels and clothes, shinier dishes, and longer-lasting plumbing.

This product is NSF Certified to NSF/ANSI/CAN 60 for use in treating drinking water. Diamond Crystal has been a trusted salt brand since 1886. Each bag contains 50 pounds (22.7 kg) of solar salt crystals.
