Types of salt for water softener

Salt is a must if you are using a salt-based water softener such as a Single tank water softener, cabinet style water softener, and twin tank water softener.

There are two different types of water softener salt

  • Sodium chloride
  • Potassium chloride
  1. Sodium chloride

The sodium chloride is commonly used and less expensive. 

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

The crystals are produced through a process called solar evaporation, therefore it has a high chance of having particle residue which can lead to tank bridging or dirt in the tank.

Pellets fits in a household that has high water usage while crystal is used in home with low water usage.

There are different types of sodium chloride

  • Rock salt for water softener

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 for water softener

Solar salt is also known as sea salt/Evaporated salt.

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

Solar salt is prepared in two method

Method 1: The sun evaporates the water leaving the salt behind in the form of crystals.

Method 2: It is produced by heating raw salt to reduce moisture returning to pure sodium chloride.

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 the purest and highest quality type of 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.

So evaporated sodium chloride type is best recommended for your salt-based water softener but in case you choose the other make sure it is pure and contain no particles which means less bridging.
In case you are on a sodium-restricted diet use potassium chloride.
