Salt for water softeners are needed to soften the water through ionization eliminating the minerals that is on the hard water such as magnesium and calcium and makes the water healthier to use and consume.

Generally there are three types of salts being used for water softener and these are the rock salt, evaporated salt and the solar salt. Rock salt is found commonly from underground salt deposits through mining. Its composition is about 98-99% sodium chloride and has .5 to 1.5 percent solubility.

Rock salt is rich with calcium sulphate. Solar salt on the other hand is different from rock salt because it can be obtained through evaporation of seawater.

Salt is produced when seawater is introduced into small ponds and left there to dry under the sun leaving salt that contains around 85% sodium chloride. Its water solubility is less that .03 percent and this is now being sold in crystal and pellet forms.

Evaporated salt can be derived through mining underground salt deposits. When mined, the dissolving salt is evaporated of its water content using energy from natural gas or coal.

This kind of salt has the highest salt content with 99.6% to 99.99% sodium chloride. But which of these salt can be favorably use for water softener?

Rock salt has substances that are not water soluble so it takes us to a lot of cleaning to the reservoir while solar salt is more soluble than evaporated salt and is more expensive than rock salt.

So far, the best thing to consider when using salt for the best water softeners is to know how much salt is needed, the times the softener needs cleaning and the built of the softener system.

If there is a minimal use of salt then you can use any of these salt alternatively.

Remember that salt for water softeners are only added during regeneration of the softener so if your system regenerates more because of frequent use of water then you will need any of these salts as well.

Just be sure to put in the best salt you can in order to avoid water softener problems.
