To make understand better what is a water softener salt let’s learn how a water softener works.

The whole process of a Water softener  happen in resin tank which has resin beads.

The resin beads in resin tanks are negatively charged.

When the hard water flows in the resin tank the resin beads which are negative charged attracted hard water minerals which are positive charged leaving you with soft water.

Over the time the resin beads attracts the minerals that are presence in hard water making them ineffective or not work properly.

The beads needs to be cleaned and that’s where water softener salt comes in to clean the over coated resin beads.

What is water softener salts

It is sodium specifically designed to use in your salt-based water softener.

A water softener softens hard water by replacing hard minerals such as magnesium and calcium with salt.

Most people well know table salt which will not work to the water softener.

The sodium is used in the resin tank to attract positively charged ions present in your hard water making your water soft.

It is also used in the brine tank to clean coated mineral on the resin beads through a process known as regeneration.

Water softener salts types

There are two different types of water softener salt

  1. Sodium chloride

The sodium chloride is commonly used and less expensive. 

It is found in various forms such as pellet, crystals, and cubes.

There are different types of sodium chloride

  • Rock salt

This type of sodium chloride is the salt that is mined on the rocks or underground.

The salt may contain a trace of other minerals.

The rock salt is less expensive but can leave a mineral deposit on your brine tank resulting in a build-up in the tank causing to be cleaned several times in a year.

  • Solar salt

Solar salt is also known as sea salt.

It is found in seawater where you collect seawater in a specific area and leave it to dry.

The sun evaporates the water leaving the salt behind in the form of crystals.

The solar salt that is used in the water softener is commonly sold in the form of pellets but you can also find it in the form of crystal or blocks.

How is solar salt made 

It is not the best water softener if you have extremely hard water or large household.

This type is more likely to form the salt bridge (salt-forming one rock mass)or create buildup.

  • Evaporated salt

It is the purest and highest quality type of sodium chloride.

It is produced by heating raw salt to reduce moisture returning to pure sodium chloride.

It has less insoluble particles this means less buildup at the bottom of the tank, therefore, the tank will not be cleaned more often.

This type is best recommended for your salt-based water softener.
