Understanding Saltwater Pools

You might be wondering, “What exactly is a saltwater pool and how does it work?” Well, let’s demystify this for you.

A saltwater pool operates on the principle of electrolysis. Salt, or sodium chloride, is added to the pool water. Now containing approximately 3,000 parts per million of salt, the water is passed through a salt cell, which is an integral part of the pool’s filtration system. This cell is where the magic happens.

The salt cell contains metal plates charged with an electrical current. As the saltwater passes through these electrified plates, the electrolysis process occurs. The salt (sodium chloride) is broken down into its basic components: sodium and chloride. The chloride is instantly transformed into chlorine gas, which dissolves in the water, creating a mild, natural chlorine solution.

This chlorine solution is what sanitizes your pool, killing bacteria and algae. The beauty of this system is that once the chlorine has done its job, it converts back into salt, ready to be reused. This cycle continues, making saltwater pools a self-chlorinating system.

Now, let’s compare this to traditional chlorine pools. In a chlorine pool, you manually add chlorine to the water in the form of liquid, chlorine tablets, or sticks. This chlorine is used up as it sanitizes the pool, and you have to continually add more to maintain a safe and clean swimming environment.

In contrast, a saltwater pool is constantly generating its own chlorine. This means:

  • You’re not handling or storing hazardous chlorine chemicals.
  • The chlorine levels in the pool are more stable, reducing the likelihood of over-chlorination or under-chlorination.
  • The water in a saltwater pool feels softer and is less irritating to the skin and doesn’t cause eye irritation.

So, in essence, a saltwater pool provides a more comfortable, low-maintenance, and safer swimming experience compared to a traditional chlorine pool.

Environmental and Cost Benefits

Beyond the health benefits, saltwater pools also offer significant environmental and cost advantages.

  • Lower Chlorine Levels

Saltwater pools generate their own chlorine through the process of electrolysis. This results in lower and more stable chlorine levels compared to traditional pools, which require frequent addition of chlorine. Lower chlorine levels are not only better for your health, but also for the environment, as less chlorine is produced and used.

  • Cost-Effectiveness Over Time

While the initial cost of installing a saltwater system can be higher than a traditional chlorine system, the long-term savings make it a cost-effective choice. You won’t be buying, storing, or handling expensive chlorine chemicals. The salt cell in a saltwater system can last several years, and the cost of replacing it is often less than the annual cost of chlorine for a traditional pool.

  • Less Maintenance Required

Saltwater pools require less maintenance than traditional pools. The self-chlorinating system means you spend less time balancing chemicals and more time enjoying your pool.


Saltwater pools, despite a higher initial cost, offer health, environmental, and cost benefits over time. They require less maintenance and are more eco-friendly, making them a worthwhile long-term investment.

Comfort and Enjoyment Benefits

The benefits of saltwater pools extend to the overall swimming experience.

  • Softer Water Feel

Swimmers often report that the water in a saltwater pool feels softer and silkier. This is due to the salt in the water, which softens it and reduces the hardness caused by minerals.

  • Absence of Harsh Chlorine Smell

Unlike traditional pools, saltwater pools don’t have that strong chlorine smell. This makes for a more pleasant swimming environment and means you won’t have that lingering chlorine smell on your skin after a swim.

  • Enhanced Swimming Experience

All these factors – the softer water, the absence of a harsh chlorine smell, the gentleness on the skin and eyes – combine to create an enhanced swimming experience. A dip in a saltwater pool is not just a swim, but a soothing, enjoyable experience that leaves you feeling refreshed and revitalized.


The benefits of saltwater pools are numerous and varied, from health and cost benefits to an improved swimming experience. It’s no wonder that more and more people are making the switch to saltwater pools.

Common Misconceptions about Saltwater Pools

As with any popular trend, there are a few misconceptions about saltwater pools that can cause confusion. Let’s address these head-on and set the record straight.

Saltwater Pools Are Not Chlorine-Free

One of the most common misconceptions is that saltwater pools are chlorine-free. This is not the case. Saltwater pools generate their own chlorine through the process of electrolysis. The difference lies in the fact that the chlorine is produced on-site, within the pool system, rather than being added manually. This results in a more stable and often lower level of chlorine, which is gentler on the skin and eyes and less irritating to the respiratory system.

Saltwater Does Not Cause Corrosion

Another concern often raised is that the saltwater in these pools can cause corrosion. While it’s true that salt can be corrosive, the concentration of salt in a saltwater pool is relatively low – about one-tenth the salinity of ocean water. This low concentration, combined with proper pool maintenance and the use of salt-resistant materials, can prevent corrosion. It’s also worth noting that many components of traditional chlorine pools are also susceptible to corrosion and require similar preventative measures.

Saltwater Pools Are Not as Salty as the Ocean

Finally, let’s debunk the myth that swimming in a saltwater pool is like swimming in the ocean. The salinity of a saltwater pool is much lower than that of the ocean. In fact, the salt concentration in a saltwater pool is closer to that of a teardrop. This means you won’t experience the same buoyancy or taste the saltiness that you would in the ocean. Instead, you’ll enjoy a soft, comfortable swimming experience that’s gentle on your skin and eyes.

In conclusion, while there are some misconceptions about saltwater pools, understanding the facts can help you make an informed decision and enjoy all the benefits that these pools have to offer.

Making the Switch: Transitioning from a Chlorine Pool to a Saltwater Pool

Are you considering transitioning from a traditional chlorine pool to a saltwater pool? It’s a decision that comes with numerous benefits, as we’ve explored earlier. But what does the transition process involve? Let’s walk you through the steps, costs, and considerations involved in making the switch.

Steps to Convert a Chlorine Pool to a Saltwater Pool

Converting your pool to a saltwater system involves a few key steps:

  1. Drain the Pool: The first step is to drain your existing pool. This ensures that the new saltwater system starts fresh, without any residual chlorine or other chemicals.
  2. Install a Saltwater Chlorinator: The next step is to install a saltwater chlorinator, which includes a salt cell and a control unit. This system will be responsible for converting the salt in the water into chlorine.
  3. Add Salt: Once the chlorinator is installed, it’s time to add salt to your pool. The amount of salt needed will depend on the size of your pool.
  4. Test the Water: After adding salt, you should test the water to ensure the salinity is at the correct level. You should also check the pH, alkalinity, and calcium hardness levels.

Costs Associated with the Transition

The cost of converting a chlorine pool to a saltwater pool can vary, depending on the size of your pool and the type of saltwater system you choose. The initial investment can be higher than maintaining a traditional chlorine pool, but the long-term savings in terms of reduced maintenance and chemical costs can make it a cost-effective choice.

Considerations Before Making the Switch

Before you make the switch, consider the following:

  • Maintenance: While saltwater pools require less maintenance than chlorine pools, they are not maintenance-free. You will still need to monitor and adjust the chemical levels regularly.
  • Equipment Compatibility: Ensure that your pool equipment and materials are compatible with saltwater to prevent corrosion.
  • Professional Installation: Consider hiring a professional to install the saltwater system. This can ensure the system is installed correctly and operates efficiently.

In conclusion, transitioning from a chlorine pool to a saltwater pool involves some initial investment and effort, but the benefits can make it a worthwhile decision.

The Challenges of Saltwater Pools

Despite the numerous advantages of saltwater pools, they also come with their own set of challenges. From higher upfront costs to potential erosion of pool components, here are some factors you should consider:

Substantial Initial Cost

The transition from a chlorine pool to a saltwater system can be quite costly. The initial investment includes the purchase of a saltwater generator and the labor costs for its installation. Although you’ll save on chlorine costs in the long run, the initial conversion to a saltwater system can be a significant expense.

Complex and Costly Maintenance

Adding a new component to your pool system, like a saltwater generator, inevitably increases maintenance requirements. The salt cell within the system needs cleaning every few months and replacement every three to seven years. As an electronic system, it may require professional servicing for major repairs or maintenance. Furthermore, while you won’t need to purchase chlorine regularly, the saltwater generator will increase your electricity usage.

Fluctuating Chemical Levels

While the idea of not manually adding chlorine to your pool is appealing, you’ll still need to regularly test and balance your water chemistry. For instance, your pH levels may rise as your saltwater generator operates. A pH level above 7.6 can cause skin irritation, burning eyes, and calcium build-up or scaling on your pool equipment.

Inefficiency in Cold Temperatures

Saltwater pool systems are ineffective at producing chlorine when the water temperature drops below 60 degrees Fahrenheit (15.5 degrees Celsius). If you live in a colder climate and don’t have a pool heater, your chlorine production will cease when the water temperature falls too low.

Potential for Corrosion

Although saltwater is generally harmless in moderate amounts, it can cause damage if it accumulates. Automatic pool covers, pool liners, metal pool equipment, and even natural stonework or landscaping near the pool can begin to erode with excessive saltwater exposure. Pay special attention to exposed metal components, especially in vinyl pools. However, fiberglass pools are generally more resistant to saltwater corrosion.
