Hard water isn't harmful but can lead to problems, including dry skin, clogging up your plumbing, and impacts on your water taste. A water softener is the only way to remove the dissolved minerals that make up hard water.
After using a water softener over and over again, you'll need to recharge the filter with more salt to continue working effectively. When you need to put your water softener through a regeneration cycle, you'll need water softener salt or sodium chloride.
There are different types of salt that can be used in a water softener, but not all are equally effective. In general, you want to use a salt that is high in purity and free of impurities. The right type of salt can help your water softener perform better and prevent damage to your appliances and water softening system.
Here are the various types of water softener salt and what to consider with each one.
Evaporated Salt Pellets
Evaporated salt is one of the most popular types of salt used in water softeners. Evaporated salt is made by an evaporation process using water and steam, which produces salt in crystalization form. Salt crystals are then processed using a drying and screening process before they're formed into pellets.
Evaporated salt forms when raw salt is converted to sodium chloride and all the moisture has been removed. What's left from this process is 100 percent pure salt. Because of this pure salt, evaporated salt pellets are highly effective at treating hard water and making it soft.
In addition, evaporated salt can help your water softener's performance in the long run and avoid water softener problems like salt bridges, which are salt crusts extending through the brine tank, and insoluble buildup. If you’re looking for an ideal salt for your best water softener shower head, then evaporated salt is the real deal.
Solar salt, commonly known as sea salt, is a byproduct of evaporated seawater. Solar salt is commonly found in pellet or crystal form. Because solar salt is made from brine, insoluble impurities in the salt can be eliminated. Solar salt's sodium chloride content is usually 99.5% or higher.
It's highly soluble, meaning it can dissolve much faster than other types of water softener salts. You can use it if your system suffers from frequent salt buildups, mushing, or bridging. Using this type of salt can help extend the life of your water softener and lower the need for frequent maintenance.
On the downside, its insoluble level is around 0.03%, which means it may cause problems like insoluble buildup and a salt bridge, which will need to be cleaned.
Rock salt is the least expensive type of water softener salt. It's extracted during rock salt mining and crushed into smaller pieces. Its sodium chloride content is around 95% or higher, depending on the mine from which it comes. Rock salt is also the rawest kind of salt on this list, which means that the salt crystals from the salt itself may contain other traces.
Rock salt is ideal for de-icing roads because it's not always ideal for water softeners because impurities like salt and shale found in the rock salt may clog or damage your water softener. Rock salt also contains a high amount of calcium sulfate and is less pure than water softener salts like evaporated salt or solar salt. It's also soluble like other types of water softener salts, which can cause buildup and require more frequent water softener maintenance.
Block salt is a type of salt that is less pure than solar salt or evaporated salt but more pure than rock salt. Block salt typically contains between 96 and 99 percent sodium chloride and is used in some water softeners. Because it's less pure, block salt may contain other minerals like calcium sulfate that can cause buildup or clog your water softener.
Potassium chloride is a great alternative to salt because it's 99.9% sodium free. Potassium chloride comes in pellet form and can be used to regenerate the softening resin. This makes it perfect for those who are looking to reduce their sodium intake.
However, it's not healthy for people with hypertension or a history of this condition in their family. Potassium chloride pellets are more expensive and are not as accessible as salt pellets. If you're thinking of switching from salt to potassium chloride pellets, you might have to increase the salt dosage program setting during the regeneration process. It's best to consult with a water softener expert if you want to use potassium chloride in your water softener.

How to Maintain Your Brine Tank
- Regularly check the salt level in your brine tank at least once a month. Once the salt in the brine tank falls below one quarter full, you run the risk of not having softened water.
- For optimal efficiency, keep the salt in the brine tank at least three or four inches above the water level but no more than four inches below the top of the tank.
- Loosen any encrusted salt around the brine tank and ensure that the large blocks are broken up before adding any new salt to it. Adding hot water to the salt blocks will help to break them up.
