Water softener salt is one way to deal with hard water. It’s used to remove the calcium and magnesium that makes “hard water”.
Their are thee water softener salts available.
-Rock Salt, obtained from deposits on the ground
-Solar Salt, obtained from harvested evaporation of sea water
-Evaporated Salt, obtained by mining underground dissolving salt deposits and isolating the salt.
These three types of salt have a point in common, they all use sodium chloride to deal with hard water.
Which water softener salt should I use?
first off, you must consider the hardness of your water. These 3 options have different levels of water solubility.
Rock salt is the cheapest alternative but for a good reason, it is less refined and contains matter that is not water-soluble which will force you to clean your water softening reservoirs more frequently.
Evaporated salt is the “cleanest” of the 3 options while Solar salt is in-between.
You do not necessarily need to choose evaporated salt even if it’s the best option, at a higher price. If you want to use rock salt or solar salt you must consider how much you need to use a water softener salt.
If you use it frequently then rock salt might become a major hassle since you will often have to clean up your water softener system. You must also consider the quality of your water softener system, it might not be able to handle certain types of salt like rock salt.
It might also simply be recommended to be used with a specific type of water softener salt. It might be harmful to try different water softener salts if you so choose but make sure to read the instructions of your model. To avoid any risk simply wait until your unit is empty before trying a new type of salt.
Your water softener should be checked every month and be kept to at least half-full. In the case of rock salt you might have to clean it up to 3 times a year which will be more often than other types of salt.
So in conclusion when choosing your water softener salt you must consider
- What salt is recommended to be used with the water softener system your purchase
- How often you are willing to clean your system ( you will have to clean it more often if you use rock salt)
- How hard your water is (the harder the water the more you should consider solar or evaporated salt over rock salt)
If you have very hard water also consider having another extra cold water line that will not be in the water softener salt system. This is because very hard water will have much more sodium and it can become hazardous over long periods of time. Other options can be to investigate into water softener salt potassium which does practically the same thing but should be better for your health. However it is more expensive than the previously mentioned salt options. Here are additional pages of information if your looking into buying a saltless water softener or other systems that use kinetic energy to power themselves such as the kinetico water softeners.
