Understanding Pool Salt

What is pool salt?

Pool salt, also known as sodium chloride, is a special type of salt specifically designed for use in swimming pools. Unlike regular table salt, pool salt is free from additives such as iodine and anti-caking agents. It dissolves easily in water, allowing the saltwater chlorinator to convert it into chlorine to sanitize the pool.

Why is pool salt necessary?

Pool salt plays a crucial role in maintaining the cleanliness and safety of your pool water. When added to the pool, it goes through a process called electrolysis, where the salt is converted into chlorine gas.

This chlorine gas then dissolves back into the water, effectively sanitizing the pool and killing bacteria, algae, and other contaminants. This process creates a self-regenerating supply of chlorine, reducing the need for traditional chlorination methods.

Determining the Ideal Pool Salt Level – How Much Pool Salt Do I Need?

To determine the ideal pool salt level, several factors need to be considered.

Factors to consider

The ideal salt level depends on various factors, including the type of saltwater chlorinator you have, the water temperature, and personal preference. It is generally recommended to maintain a salt level between 2,500 and 4,000 parts per million (ppm) for most saltwater pools.

Recommended salt levels

Different saltwater chlorinators may have specific recommendations for salt levels. It is essential to consult the manufacturer’s guidelines or your pool professional to ensure you are within the recommended range.

Deviating significantly from the recommended salt levels can affect the efficiency of the chlorinator and the overall water balance.

Calculating the required amount of pool salt

To calculate the amount of pool salt required, you need to know the volume of your pool in gallons and the desired salt level in ppm. There are various online calculators and formulas available to assist you in this calculation. By inputting the necessary information, these tools can provide you with the exact amount of salt needed for your pool.

Pool Size and Salt Quantity

The size of your pool directly affects the quantity of salt required to reach the desired salt level.

Matching salt quantity to pool size

As a general rule of thumb, larger pools require more salt, while smaller pools need less. This is because the salt needs to be adequately distributed throughout the entire pool volume for optimal chlorination.

By matching the salt quantity to your pool size, you can ensure the right balance of saltwater concentration.

Salt quantity calculations

To calculate the salt quantity accurately, you need to know your pool’s volume in gallons and the desired salt level. By multiplying the pool volume by the recommended salt level in decimal form (ppm/1,000,000), you can determine the amount of salt required.

It’s important to remember that salt doesn’t evaporate from the pool, so you won’t need to replace it regularly unless you experience water loss due to backwashing or splash-out.

Adding Pool Salt

Once you have determined the required amount of pool salt, it’s time to add it to your pool.

Step-by-step process

  1. Start by turning on the pool pump to ensure proper circulation.
  2. Gradually add the recommended amount of pool salt to the water.
  3. Distribute the salt evenly throughout the pool.
  4. Allow the salt to dissolve completely before proceeding.

Distributing salt evenly

To distribute the salt evenly, you can walk around the pool while pouring it in a steady, sweeping motion. Alternatively, you can dissolve the salt in a bucket of water and then pour the solution into the pool. Be cautious not to pour the salt directly onto pool surfaces or near pool equipment, as it can cause corrosion.

Testing and Adjusting Salt Levels

After adding salt to your pool, it’s crucial to test and adjust the salt levels regularly.

Salt testing kits

Salt testing kits are readily available at pool supply stores and online. These kits use test strips or electronic meters to measure the salt concentration in your pool water. Follow the instructions provided with the testing kit to obtain accurate results.

Adjusting salt levels if necessary

If the salt levels are too low or too high, adjustments are required. To increase the salt concentration, you can add more salt following the recommended calculations. Conversely, if the salt levels are too high, diluting the pool water with fresh water is necessary. It’s important to maintain the recommended salt level to ensure the optimal performance of your saltwater chlorinator.

Maintaining Pool Salt Levels

Regular testing and monitoring of pool salt levels are essential for proper maintenance.

Regular testing and monitoring

Make it a routine to test the salt levels at least once a week using the salt testing kit. This will help you identify any fluctuations or imbalances in the salt concentration. It’s also good practice to record the test results and keep track of the changes over time.

Balancing other pool chemicals

Maintaining proper pool salt levels is just one aspect of pool water chemistry. It’s crucial to regularly test and balance other chemicals such as pH, alkalinity, and cyanuric acid. A well-balanced pool will provide a safe and enjoyable swimming experience for you and your family.

Benefits of Proper Pool Salt Levels

Maintaining the proper pool salt levels offers several benefits to pool owners.

Enhanced swimmer comfort

Saltwater pools are known for their gentle and silky feel on the skin. The appropriate salt levels create a comfortable swimming environment, reducing skin and eye irritation commonly associated with traditionally chlorinated pools.

Effective chlorination

With the right amount of pool salt, your saltwater chlorinator can produce an optimal level of chlorine to keep your pool water sanitized. This ensures effective chlorination, minimizing the risk of waterborne illnesses and keeping the pool water crystal clear.

Reduced maintenance and costs

Proper pool salt levels can lead to reduced maintenance and costs. The self-regenerating chlorine produced by the saltwater chlorinator eliminates the need for storing and handling traditional chlorine chemicals. This not only saves time and effort but also reduces the overall cost of pool maintenance.

Potential Issues with Pool Salt

While pool salt offers numerous benefits, it’s essential to be aware of potential issues that may arise.


Adding excessive salt to the pool can lead to over-salting, which can be unpleasant for swimmers and detrimental to pool equipment. Over-salting may result in the corrosion of metal parts, including pool heaters and ladders. It’s crucial to follow the recommended salt levels and avoid excessive salt additions.


On the other hand, inadequate salt levels can compromise the efficiency of the saltwater chlorinator. Insufficient salt concentration can lead to ineffective chlorination, potentially allowing bacteria and algae to thrive in the pool water. Regular testing and monitoring will help you avoid under-salting issues.

Saltwater system compatibility

Before considering a saltwater pool, it’s important to ensure that your pool equipment is compatible with saltwater systems. Saltwater can have corrosive effects on certain materials, such as certain types of pool liners or non-saltwater-friendly equipment.

Consulting with a pool professional can help you determine the compatibility of your existing equipment.
