Best Salt for Your Water Softener: Pellets, Crystals or Potassium?

By Upright Water Co2 min read

I'm Aiden with Upright Water Co. Once you own a softener, the salt aisle can be confusing. Here's the simple version. Always follow your manufacturer's manual first.

The main types

  • Evaporated salt pellets. The highest purity, with the least residue left in the brine tank.
  • Solar salt crystals. Made by evaporating seawater, with slightly more impurities. Some systems are fine with crystals.
  • Rock salt. The cheapest and the least pure. It can leave sediment and mean more tank cleaning.
  • Potassium chloride. A sodium-free alternative.

Signs of trouble

  • Salt bridge: a hard crust with empty space under it. Break it up gently.
  • Mushing: sludge at the bottom of the tank.
  • Water feels hard again even though there's salt in the tank.

Tips

  • Keep the tank about half full, and don't overfill.
  • Stick with one type rather than mixing.
  • Check monthly, and more often in summer when you use more water.
