What Do Water Softener Salts DO? Is It Safe To Eat Water Softener Salt?

The science behind water softeners is easy. To know how water softeners and the salts work, it’s helpful to understand what makes the water hard in the first place. As we shared above, the presence of excess minerals like magnesium and calcium in the water makes it hard water. In scientific terms, you can say that it is ‘hard ions’ that make the water hard.

This is where water softeners and the salts step into the picture. The water softeners contain salts. And when the water passes through the water softener, the salts or salt ions replace the hard ions making the water soft. The salts ensure the reduction of hard ions by replacing them with salt ions.

Water softeners aren’t like water filters. It’s easy to confuse both. Water filters remove all sorts of contaminants from the water. Whereas water softeners simply exchange the hard ions with the salts ions and make hard water soft.

As you must’ve figured out by now, salt is the main ingredient in water softeners. Without salt, a water softener will not work and is of no use. Here is what happens inside a water softener during the process of softening water:

  • Every water softener has a resin tank. The exchange between the hard and salt ions takes place on these resin tanks.
  • These resin beads are covered with the essential salts. When water flows through the water softener, it comes in contact with the resin beads covered in salts.
  • Naturally, when water flows through the resin beads, the salt ions take the place of the hard ions in the water and soften the water. It is in the resin beads that the hard and salt ions exchange places and give you soft water.

Now, when you use the water softeners almost every day, eventually, the salts from the resin beads wear out. Without these salts, there can be no soft water. So this is where you need to add more salts to the resin beads so you can keep getting soft water. And this is where our best salts for water softeners list will be helpful.

All you need to do to replace the resin beads is add the salts to the softener’s brine tank. While recharging the resin beads, the salt ions will exchange places with the hardness ions within the brine tank. And as the two ions exchange places, any excess of minerals in the water will be rinsed and pushed into the wastewater drain.

How Can I Add Salt to a Water Softener? Can You Overfill a WaterSoftner with Salt?

An amazing thing about water softeners is that they regenerate themselves. All you need to do is add salts to the softener’s brine tank.

But if you forget to add the salts to the brine tank, then you may need to do it manually to regenerate the softener. To manually regenerate the softener, you will need two 40 pound bags of salts for water softeners and a wet rag. The quantity of salt you will need will depend on the size of the water softener.

Once you have the salts and the rag, you need to clean the brine tank. Yes, before you add any more salts to the tank, you need to clean it with a rag. The brine tank’s sidewalls contain buildup from before. So, clean the buildup from the side walls as it is important for the tank to be clean before you add salts to it.

After you are done cleaning the brine tank, pour the two 40 pounds of salts into the water softener. According to the size of your water softener unit, it is best to not put more than two 40 pounds of salts in it. Ensure that the brine tank is only half full.

Once you are done adding the salt to the brine tank, you need to manually regenerate the water softener. Most water softening units come with a control panel that has a button for manual regeneration.

You need to keep the button pressed until the water softening restarts and begins the regeneration process.

It is important for you to know that while water softeners can automatically regenerate themselves, they also require manual regeneration from time-to-time. The manual regeneration ensures that the water softening unit is clean, which helps it run smoothly for many years.

  • How Can I Tell If My Water Softener Needs Salt?

By now, you know very well that without salts, a water softener is of no use. Salt is the most important part of the water softening process. And so it is crucial to know when you need to add salt to the brine tank. If you forget to add salt, you will be using hard water in your house, causing different issues.

How much salt you need to add to the unit depends on a few important factors. The hardness level of the water, the model of water softener you have, the frequency of salt replacement, the size of the brine tank, and the quantity of water your household uses are the factors that determine how much salt you need to add to the unit.

That said, to know when you need to add salt to the water softener, you can take into consideration the following:

Check the salt levels

One of the easiest ways you can know when you need to add more salts to the softener is by checking the salt levels inside the brine tank. All you need to do is lift the brine tank’s cover and have a look inside. If you see that there is less salt in the tank and the tank is less than half, then you need to add more salt to it until the tank is half full.

The age of your softener

Another easy to tell when you need to add salt to the tank is considering the age of your softener. With older water softeners, you need to add salt more often than newer ones. For example, if you have a water softener that is more than 10 years old, it will use more salt to soften the water than a newer water softener.

As water softeners become old, they decrease in efficiency and end up using more salts than when they did when they were new. With newly bought softeners, you need to add salt to them every 5 to 8 weeks. But with the older ones, you need to keep checking the brine tank to determine if it needs more salt.

Check from salt bridges

Another way to tell if you need to add salt to the brine tank is by checking for salt bridges in it. It is important to check every two or 3 months and ensure that salt bridges do not form inside the tank. Salt bridges limit the efficiency of the water softening by slowing down the process of ion exchange.

Salt bridges can form when the salt level does not decrease even after months of using the softener. To avoid the formation of salt bridges, you can place the softener in a low-humidity area, use high-quality salt, and ensuring that the brine tank is always half full of salt.

No soft water

One of the easiest ways to tell if the brine tank needs salt is when you see hard water flowing through your faucets. After installing a water softener and using it every day, you will easily be able to tell when the water is hard or soft. So, when you find that hard water is running through the faucets, it is time to add salt to the brine tank.

Frequently Asked Questions About Best Salts for Water Softeners in Australia

  • Is It Safe To Drink Softened Water?

Yes, soft water is extremely safe to drink. In fact, drinking hard water is detrimental to health and drinking soft water helps you stay healthy. A common misconception is that when we add some or put water through a restructuring process, it isn’t safe to drink anymore. Nothing could be far from the truth than this misconception.

All the water softener does is that it removes excess minerals from the water and balances the water. A healthy quantity of minerals remains in the water, making the water safe to drink and use for cooking.

  • How Much Salt does Sodium Chloride Water Softener Salt Contain? 

Sodium chloride is a salt that is used in water softening systems. As there are so many people with kidney issues and various other renal issues, it is good to know the salt content in the water that is softened by sodium chloride. For example, if you drink 2 liters of water every day, it would contain about 125 grams of salt in it.

  • Is it Safe to Use Food-Grade Salt to Soften The Water?

This is a common question that occurs when you use a water softener. It is recommended not to ever use food-grade salt (table salt) in the water softener. This is because crystals of table salt are much smaller than the crystals of the salt made, especially for water softeners.

And because of the smaller size of the crystals of table salt, they can easily form salt bridges inside the salt tank, which hinders the water softening process.

  • Can I Mix Different Types of Salts in My Water Softener?

Sometimes it may happen that you won’t find the same type or brand of salt that you used before when you had to add salt to the brine tank. In such a situation, you will need to buy a different type or brand of salt to add to the brine tank and mix different types of salts together. This is completely fine as different types of salts can be mixed together, and they still work perfectly fine and give you soft water.

But in some situations, you will need to be more careful and double-check a few things. For example, water softeners come in different types. You will find all in one water softeners and single tank water softeners. For these types of softeners, manufacturers recommend that you use pellets as they prevent the formation of salt crust and bridges around the bank.

Another thing to keep in mind is that water softeners that do not have a salt screen at the bottom will work better with pellets or cubes. Pellets and cubes prevent the salt crystals from going into the salt draw pipe.


Salt to a water softener is like air to humans. Without salts, water softeners won’t work and are of no use. And as important as salts are, it is even more important to use high-quality salts for water softeners. Low-quality salts may not soften the water and retain the hardness of the water. Low-quality salts are also more prone to forming salt crusts and bridges in the brine tank.

And so, we hope that the 6 best salts for water softeners in Australia list we have provided you with has given you enough options to choose the best quality salts. We also hope that our extensive buying guide has provided you with enough information to help you make a well-informed choice.
