Summary: Understanding water softener salt is crucial for maintaining your system. This guide covers salt types, usage patterns, costs, and maintenance tips for Houston's hard water conditions.
Why Your Water Softener Needs Salt
Water softeners use ion exchange to remove calcium and magnesium from your water. The resin beads in your softener become coated with these minerals and need to be "recharged" with sodium ions from salt.
Types of Water Softener Salt
Solar Salt (Evaporated Salt)
- Source: Natural salt deposits, evaporated by sun
- Purity: 99.6% pure sodium chloride
- Form: Crystals or pellets

- Best for: Budget-conscious homeowners
Potassium Chloride
- Source: Mined potassium salt
- Purity: 99% pure potassium chloride
- Form: Pellets
- Cost: $15-25 per 40lb bag
- Best for: Low-sodium diets, environmental concerns
Block Salt
