Can You Use Water Softener Salt In A Pool?

Have you ever wondered if you can use water softener salt in a pool? Well, wonder no more!

This blog post will explore whether or not water softener salt is safe to use in pools. We’ll also provide some tips on properly caring for your pool.

So whether you’re a Dyer or hiring a professional, read on to learn everything you need to know about keeping your pool clean and using a softener salt system.

What is water softening salt?

Water softening salt removes hardness from hard water.

Hardness is caused by minerals, such as magnesium and calcium hardness, in water.

Water softening salt is also known as sodium chloride or table salt (solar salt).

The water softener uses salt in the brine tank (salt tank) to soften and provides fresh, clean water in your home.

It is available in different granule sizes to suit your needs, such as 6-12mm pellets, 8-16mm crystals, and 10-20mm rock salt.

It is safe to use water softening salt in a pool. Water treatment is a form of chlorine generator used to sanitize softened water.

However, it is essential to use the appropriate amount of salt pellets for your pool, as too much salt crystal can make the pool water uncomfortable to swim in.

Why do we use salt in swimming pools?

People add salt to swimming pools for several reasons:-

  1. It helps to keep the water clean and clear, it can help prevent algae growth, and it can also make the water feel more comfortable for swimmers.
  2. Salt is a natural disinfectant, and it can help kill bacteria and other organisms in the water.
  3. It also helps prevent the build-up of scale and other deposits on the pool surfaces.
  4. Swimmers often find that saltwater feels more refreshing and comfortable than chlorine-treated water.
  5. Salt is a natural ingredient, it doesn’t have the harsh chemical smell that chlorine can sometimes have.
  6. So next time you’re swimming in a pool, take a moment to appreciate the salt (potassium chloride) that’s helping to keep you safe and comfortable!
  7. It is also worth mentioning that you should always check with your pool maintenance company or local swimming pool regulations before adding salt to your pool, as there can be restrictions on the amount used.
  8. If the amount of salt in your water is high, we will feel that we are taking a bath in a salt pool, and to check the amount of salt in the water, we can use a salt test strip.

Which should you use, pool salt or water softener salt?

When it comes to keeping your swimming pool clean, you have a couple of different options for the type of salt crystal you use.

You can either use pool salt or water softener salt. But which one should you use?

The short answer is that you can use either type of swimming pool salt in water.

However, water softener salt is a little bit cheaper, and it also has a higher concentration of chlorine, which makes it a good choice if you want to keep your pool clean and free of algae.

If you have a saltwater pool, you should use pool salt. It is because water softener salt can damage the cells in your pool’s filtration system.

So, if you’re not sure which type of salt crystal to use, go with pool salt. It’s a little bit more expensive, but it’s the safer option for your swimming pool.

Effects of using a water softener salt in your pool

Water softener salt is a popular choice for people who have pools, and it’s often used to help prevent calcium build-up and overflowing the hard water.

However, there are some potential downsides to using water softener salt in your pool.

  • One potential downside is that the salt (potassium chloride) can cause the pH level of the pool water to become too acidic. It can be harmful to both the pool and swimmers.
  • Using water softener salt can cause the water to become cloudy. It can make it difficult to see the bottom of the pool and make the softened water more inviting to algae growth.
  • If you choose to use water softener salt in your pool, it’s essential to be mindful of the amount you’re using. Too many salt pellets can cause damage to the pool and make it difficult to maintain.
  • It’s also essential to properly care for your pool and be sure to test the pH level regularly and shock the pool as needed. With proper care, your pool water will be safe for swimming and enjoyable for everyone.
  • The increased salt level will feel like we are swimming in a salt pool, so we need a salt test strip to check the status.

So, can you use water softener salt in a pool? The answer is yes, but it’s essential to be mindful of the amount you’re using and adequately care for your pool.

With proper care, your swimming pool will be safe for swimming and enjoyable for everyone.

Pool salt vs. water softener salt

There are differences like:

Pool salt is mined from the earth and typically contains a higher sodium chloride (NaCl) concentration than softener salt.

On the other hand, water softener salt pellet is often made from evaporated seawater and typically has a lower concentration of sodium chloride.

Pool salt can dissolve quickly to help maintain a consistent chlorine level in the hard water.

Water softener salt dissolves more slowly, so it doesn’t create a mess when poured into a softener.

So, can you use a water softener salt system in your pool? The answer is yes! We can use water softener salt in pools, but it’s essential to keep some things in mind.

First, because water softener salt has a lower concentration of sodium chloride, you’ll need to use more of it to achieve the same results as swimming pool salt.

Second, water softener pellets take longer to dissolve, so they can create a mess if you’re not careful.

Finally, make sure to read the label on your water softener salt to determine whether or not it’s safe for use in pools.


Q. Can I use rock salt in my swimming pool?

Yes, you can use rock salt in your pool. It is a common ingredient to keep the chlorine levels down and prevent algae growth.

You will want to ensure that it does not get into the filter system, as this could cause problems with the pump or other parts of the filtration system.

I don’t think you should use rock salt for your pool, but I’m not an expert on this topic. 

There are some best alternatives available. For example, you can buy a “Pool Salt,” which contains sodium bicarbonate (baking soda).

This is an effective alternative for keeping chlorine levels low but should be avoided if you have any issues with your water chemistry.

Q. Is pool salt and water softener salt the same?

A. No, pool salt and water softener salt are not the same. Pool salt is a type of salt specifically designed for pools, and it is pure saltwater in pools that do not contain any impurities.

On the other hand, water softener salt is a type of salt used to soften water, and it includes a variety of contaminants, including magnesium and calcium hardness.

Q. What is pool salt used for?

A. Pool salt makes the soft water in a swimming pool more alkaline, and it also helps prevent the growth of algae and bacteria.

Q. Can I put bleach in my water softener?

Yes, you can put bleach in your water softener. This can help to keep the unit clean and functioning properly.

You should only use a small amount of bleach though, as too much can damage the unit.

Always follow the manufacturer’s instructions when using bleach with your water softener.

Q. Can I use water softener salt in my hot tub?

A. Yes, you can use water softener salt in your hot tub. Because water softener pellets are pure salt, they will not leave any residue in your hot tub.

Just follow the manufacturer’s instructions on how much salt to use.

Q. can I use water softener salt on my driveway?

A. No, you should not use water softener salt on your driveway. The salt level increases, eroding the pavement and damaging it.

You need to use a type of salt specifically designed for this purpose, such as rock salt or ice melt.


The softener system uses a brine tank (salt tank) to treat water for your whole home.

So, there you have it! You can use water softener salt in your pool, but be sure to follow the manufacturer’s instructions on how much salt pellet to use.

And, as always, be sure to properly care for your pool to keep it looking its best. Thanks for reading!
