We understand that choosing the right pool is a significant investment, both financially and in terms of your time and energy.

What is a Saltwater Pool?

Understanding How Saltwater Pools Work

A saltwater pool is different from what many people imagine. It doesn’t involve swimming in salty ocean water but instead uses a salt-chlorine generator to maintain the pool’s cleanliness. The generator utilizes a process called electrolysis to convert salt (sodium chloride) in the water into chlorine gas, which then dissolves into the pool to form hypochlorous acid. This acid is what sanitizes the water, similar to the chlorine used in traditional pools. Simply put, salt systems produce liquid chlorine, that’s it.

Comparison with Traditional Chlorine Pools

Unlike traditional pools that require the weekly manual addition of chlorine tablets, saltwater pools generate chlorine automatically. This is often seen as a benefit, but it doesn’t mean that saltwater pools are “free” of chlorine. Instead, they use a different method to introduce chlorine into the water.

Misconception 1: Saltwater Pools Are Chlorine-Free

The Truth About Chlorine in Saltwater Pools

One of the biggest myths surrounding saltwater pools is that they are chlorine-free. In reality, saltwater pools only rely on chlorine for sanitation. The difference is that the chlorine is produced by the salt-chlorine generator, not manually added. This misunderstanding can lead to disappointment, especially for those who have chosen saltwater pools to avoid chlorine entirely.

Pros and Cons of Chlorine Levels in Saltwater Pools Compared to Traditional Pools

Saltwater pools can have more consistent chlorine levels since the generator continuously produces chlorine. However, this chlorine is generated at a higher pH, roughly a pH of 8.0, which may require additional chemical balancing. Maintaining the pH can be made easier with the purchases of acid feeder that can automated to dose automatically. While saltwater pools may feel gentler on the skin, they are not suitable for people with severe chlorine sensitivities.

Misconception 2: Saltwater Pools Are Maintenance-Free

What Maintenance Really Looks Like for Saltwater Pools

Many homeowners are under the impression that saltwater pools require no maintenance. While these pools do reduce the need for manual chlorine handling, they still require regular upkeep. Tasks such as monitoring the salt levels, cleaning the generator cells, and maintaining proper water balance are essential, especially with the pH levels being typically higher.

Comparison of Maintenance Requirements with Traditional Pools

Traditional chlorine pools require regular addition of chlorine and pH balancing, while saltwater pools focus more on maintaining the salt-chlorine generator and adding acid to lower the pH levels. Both types of pools require attention; the difference lies in the specific tasks involved.

Tips for Easy Maintenance

• Regularly check and clean the salt-chlorine generator cells.
• Monitor and maintain the salt levels to ensure proper chlorine production.
• Balance the water chemistry to prevent scale buildup and equipment damage.
• Weekly monitor the pH levels and add stabilizer/muriatic acid to lower the pH to 7.2 – 7.6

Misconception 3: Saltwater Pools Taste Like Ocean Water

Understanding the Salinity Levels in Saltwater Pools

Another common misconception is that saltwater pools taste like the ocean. In reality, the salinity levels in a saltwater pool are about 10 times lower than in seawater, roughly equivalent to the salt content of a human tear. This low salt level is not enough to create a noticeable salty taste but it is the “hero” in why the water feels soft.

Why Saltwater Pools Don’t Taste Like the Sea

Due to the low concentration of salt, saltwater pools do not have the briny taste associated with ocean water. The primary purpose of the salt is to generate chlorine for sanitation, not to create a saltwater experience.

Benefits of Low Salinity in Saltwater Pools

• Softer, smoother feeling water.
• Reduced irritation for swimmers compared to traditional chlorine pools.

Misconception 4: Saltwater Pools does NOT Damage Pool Equipment

The Impact of Saltwater on Pool Equipment

It is true that saltwater can be corrosive, which may raise concerns about potential damage to pool equipment. Over time, salt can affect materials like natural stone, metal fixtures, and even pool heaters. However, this damage is often manageable with proper care and the use of salt-resistant materials.

Common Concerns and the Reality of Saltwater Effects

While saltwater can cause wear on certain materials, it typically does so at a slow rate.

Preventative Measures to Protect Pool Equipment

• Use materials specifically designed for saltwater environments.
• Regularly rinse pool fixtures and equipment with fresh water (especially on deck areas near common entry and exit points of the pool).
• Apply protective coatings to vulnerable surfaces.

Misconception 5: Saltwater Pools System Are Expensive to Install and Maintain

Cost Analysis: Saltwater Pools vs. Traditional Pools

Saltwater pools generally have higher upfront installation costs due to the salt-chlorine generator, which can range from $1,500 to $2,500. However, these pools may offer savings over time by reducing the need to purchase chlorine tablets regularly. It is highly likely that more muriatic acid will be purchased throughout the year as compared to chlorine tables because tables will often have stabilizer manufactured in hem 

Long-Term Maintenance Costs

While saltwater pools may require less frequent chlorine purchases, other maintenance costs, such as generator replacement and additional chemicals, should be considered.

How Saltwater Pools Can Be Cost-Effective in the Long Run

Despite the higher initial cost, saltwater pools can save money over time with reduced chlorine tablet purchases, until its time to replace the salt cell. A well-maintained salt cell can last anywhere from 3 years to 5 years on average. Think of a salt cell like a battery, at some point its going to die and need to be replaced at a new salt cell cost, plus labor.

FAQs About Saltwater Pools

How Long Does a Saltwater Generator Last?

Typically, a saltwater generator lasts between 3 to 5 years, depending on usage and maintenance.

Can You Convert a Traditional Pool to Saltwater?

Yes, it is possible to convert a traditional chlorine pool to a saltwater pool by installing a salt-chlorine generator.

Are Saltwater Pools Safe for Pets and Kids?

Depends, saltwater pools are generally safe for pets and kids. However, those with chlorine sensitivities should still exercise caution.

Why Saltwater Pools Might Be Right for You

Saltwater pools offer a range of benefits, including softer water and potentially reduced long-term costs. However, it’s essential to understand that they are not chlorine-free and do require regular maintenance. If you value the convenience of automatic chlorine generation and understand how saltwater pools truly work, they can be an excellent choice for your home.
