How Water Softener Salt Works

A home water softener uses resin beads to catch the calcium and magnesium that make water hard. Over time the resin fills up. During regeneration, the softener rinses the resin with brine from the brine tank, which flushes the hardness minerals out so the resin can keep working.

The salt you add is what makes that brine. That is why the type and quality of salt matter: it has to dissolve steadily, leave little residue and suit the design of your tank.

Start With Your Softener Manual

Before you buy, check the manual or the label on your softener. Most home units accept pellets and many accept crystals. Some are set up for potassium chloride. If your manual names a salt type, stay with it. If you are not sure, pellets are the most common choice for single-tank cabinet and tall brine tank systems.

Which One Should You Buy?

Solar Salt Crystals

Solar salt comes from evaporating sea water with sun and wind. All Natural Solar Salt comes in 8, 40 and 50 lb bags, High Purity Solar Salt Crystals come in a 50 lb pail, and CrystalPure Solar Salt Crystals are labeled 99.5% pure in an 8 lb bag. Morton Pure and Natural Crystals and Cargill Water Softener Salt Crystals round out the crystal options.

Pellets

Pellets are pressed salt in a uniform shape. They are a common choice for single-tank softeners. Options include Solar Salt Pellets, Cleansing Formula Pellets, Morton Clean and Protect, Diamond Crystal Bright and Soft in a 50 lb bag and Cargill Pellets in a 40 lb bag.

Rust Remover and Iron Formulas

If your water leaves orange or brown stains, a salt made for iron can help keep the resin clean. Look at Snow Shield Solar Salt with Rust Remover, Peach Country Salt with Rust Remover, Morton Clean and Protect Plus Rust Defense and Diamond Crystal Iron Fighter. Do it Best Water Softener Salt comes as cubes, cubes with rust remover or extra-coarse crystals.

Potassium Chloride

Some households prefer a sodium-free option. Morton Potassium Chloride Pellets and Nature's Own Potassium Cubes both come in 40 lb bags. Check that your softener can use potassium and whether its settings need to change.

Solar Salt vs Pellets

Both are sodium chloride. The difference is form. Crystals are loose, natural pieces that let water move around them. Pellets are pressed into a uniform shape. Your softener design matters more than the salt itself, so follow the manual. Whatever you choose, stick with it rather than switching back and forth.

How to Add Salt to Your Softener

  • Lift the brine tank lid and look at the salt level.
  • Break up any crust you see before adding more salt.
  • Pour salt in until the tank is about half full.
  • Check again in a month and top off as needed.

How Much to Order

Salt use depends on how hard your water is and how much water your household uses. A simple approach is to check the tank monthly for a couple of months and note how many bags you add. That tells you how much to keep on hand. Many customers like to order a few bags at a time so they always have one in the garage.

What to Watch Out For

  • Salt bridges. A hard crust can form across the tank and leave a hollow space under it, so the salt never reaches the water. Push gently on the surface with a broom handle to break it up.
  • Mushing. Salt that turns to sludge at the bottom of the tank can block the brine intake. Let the tank run low and clean it if you see this.
  • Mixing types. Do not mix salt types in the same tank. Let it run low before you switch.
  • Overfilling. Keeping the tank about half full is plenty for most homes.

Buying by the Pallet

Water softener salt is a steady, year-round purchase. For property managers, rental owners or anyone who wants a season of salt at once, pallets ship by LTL freight and only the freight is quoted. The per-bag price stays the same. Start on the bulk and pallet orders page or browse bulk and pallet orders. For dishwashers with built-in softeners, see specialty salt, and for salt water pools, see pool and spa salt.

Quick Answers

Pellets or crystals: which is better for my water softener?

Both work in most home softeners. Pellets are compressed evaporated or solar salt and suit most tall brine tanks. Solar crystals are a good fit for many two-tank systems. Check your softener manual and stay with the type it recommends.

Can I use potassium chloride instead of salt?

Many softeners can run on potassium chloride in place of sodium chloride. Check your manual first, since the softener settings may need to change when you switch.

How often should I add salt to my water softener?

Check the brine tank about once a month and keep it roughly half full. How fast salt goes down depends on your water hardness and how much water your household uses.

Can I mix different types of softener salt?

It is best not to. Mixing pellets, crystals or potassium can cause uneven dissolving and buildup in the brine tank. Let the tank run low before switching types.

What is solar salt?

Solar salt is sea salt made by evaporating salt water with sun and wind. It is sold as crystals or pressed into pellets for water softeners.
