What Is a Salt Water Pool?
A salt water pool uses a generator to convert dissolved salt into chlorine through electrolysis, creating a steady and gentle sanitizing effect without the need for regular chemical dosing. This results in softer water that many swimmers find more comfortable on the skin and eyes, and knowing how to tell if a pool is salt or chlorine often comes down to spotting a generator or noticing the smoother feel of the water. With this added comfort and technology, it’s worth noting that
an in-ground pool costs an average of $65,909,
making the choice of system an important factor in overall investment.
Pros of a Salt Water Pool
1. Gentler on Skin and Eyes
Salt water pools produce chlorine at a steady, lower level, which helps reduce irritation compared to traditional chemical dosing. Swimmers often notice fewer red eyes and less dryness after long swims. This comfort is one of the most talked-about benefits of salt water pool systems.
2. Softer Water Feel
The presence of dissolved salt gives the water a smooth, silky texture that feels different from standard chlorine-treated pools. Many swimmers describe it as more refreshing and less harsh on the body. This sensory difference often stands out when comparing a salt water pool vs chlorine.
3. Reduced Chemical Handling
With a salt system, chlorine is generated automatically, so owners don’t need to store and handle as many harsh chemicals. This lowers the risks associated with accidental spills or improper storage. It also helps explain why pools have chlorine alternatives like salt-based systems gaining attention.
4. Consistent Chlorine Levels
Electrolysis provides a steady supply of chlorine, avoiding the highs and lows that can occur with manual dosing. This means fewer sudden spikes that lead to strong chemical odors or imbalances. A big benefit of salt water pool setups is this reliability in water quality.
5. Lower Long-Term Chemical Costs
While the initial setup can be more expensive, salt systems reduce the need for frequent chlorine purchases over time. This can create meaningful savings across several pool seasons. For many, this financial trade-off becomes a deciding factor in the salt water pool vs chlorine debate.
6. Less Noticeable Chlorine Smell
Because chlorine levels remain consistent and lower, the strong chemical odor common in traditional pools is greatly reduced. This makes the pool environment feel cleaner and more inviting. It’s another reason swimmers list among the key benefits of salt water pool systems.
Cons of a Salt Water Pool
1. Higher Initial Installation Cost
Salt water pools require a salt chlorine generator, which adds significantly to upfront expenses. This cost can be a hurdle compared to the lower entry point of traditional chlorine systems. In many salt water pool vs chlorine discussions, budget is the first drawback noted for salt systems.
2. Risk of Corrosion
Salt is naturally corrosive and can damage certain pool equipment, metal fixtures, and even surrounding surfaces if not carefully managed. Over time, this may lead to more frequent repairs or replacements. This reality can outweigh some of the benefits of salt water pool setups when considering long-term durability.
3. Specialized Repairs and Maintenance
When issues arise, salt chlorine generators and their components often require skilled technicians. Repairs can be more expensive and less convenient than the straightforward fixes of chlorine pools. This complexity is one factor behind why pools have chlorine as the long-standing standard.

Salt water systems use generators that run on electricity, which can add to monthly utility costs. While not extreme, this increase can make operating expenses higher than anticipated. It’s another trade-off to weigh in the salt water pool vs chlorine decision.
What Is a Chlorine Pool?
A chlorine pool uses manually added tablets, granules, or liquid chlorine to disinfect the water and control bacteria, algae, and other contaminants. This classic method has remained popular for decades because chlorine is cost-effective, widely available, and highly reliable. When asking how to tell if a pool is salt or chlorine, a chlorine pool can usually be identified by the absence of a salt generator and the need for regular chemical dosing. While it requires more handling, many pool owners prefer chlorine systems for their proven performance and ease of upkeep.
Why Do Pools Have Chlorine?
Pools have chlorine because it is one of the most effective and reliable sanitizers for keeping water safe to swim in. Chlorine kills harmful bacteria, viruses, and algae while also helping to maintain clear, balanced water. Its affordability, availability, and proven track record explain why pools have chlorine as the standard treatment method for decades. Even with newer alternatives like salt water systems, chlorine remains the foundation of pool sanitation worldwide.
Pros of a Chlorine Pool

Frequently Asked Questions (FAQs)
What is the healthiest pool to swim in?
The healthiest pool is one that maintains balanced water chemistry and consistent sanitization, whether it uses chlorine or a salt water system. Salt water pools are often praised for being gentler on skin and eyes, while still providing safe levels of chlorine through electrolysis. Chlorine pools, on the other hand, remain effective and safe when properly maintained. Ultimately, the healthiest option depends on how well the system is managed rather than the type alone.
What is the least toxic pool system?
Salt water pools are generally considered the least toxic because they reduce the need for direct chemical handling and keep chlorine levels more stable. This minimizes harsh odors and lowers the chance of irritation for sensitive swimmers. While both systems rely on chlorine, salt systems use a softer, automated approach. This difference is often highlighted in the ongoing salt water pool vs chlorine debate.
Do I need to add chlorine to a saltwater pool?
Yes, salt water pools still require chlorine, but it is generated automatically by the salt chlorine generator. The generator converts salt into chlorine through electrolysis, maintaining sanitation with fewer fluctuations. Occasionally, supplemental chlorine may be needed during heavy use or after a storm. This reality helps explain why pools have chlorine as the base sanitizing agent, regardless of system type.
How do you know if your pool needs salt?
A pool typically signals the need for more salt when chlorine production decreases, the water turns cloudy, or a generator’s indicator light shows low levels. Testing the water with a salt meter or test strips provides an accurate reading. Salt water pools usually require a range of 2,500–3,500 ppm for optimal performance. Knowing this range ensures the system works effectively, much like understanding why pools have chlorine clarifies its role in safe swimming.
What happens if the salt level is too low in the pool?
If the salt level is too low, the generator cannot produce enough chlorine to sanitize the water properly. This leads to cloudy water, higher risk of bacteria or algae, and an overall drop in water quality. Swimmers may also notice the water feels less soft or refreshing. Correcting the balance by adding salt quickly restores the system’s ability to keep the pool safe.
Is a salt water pool better than chlorine?
Not necessarily—it depends on your priorities. Salt water pools provide softer water that’s gentler on the skin and eyes, and they reduce the need for handling chemicals every day. However, they cost more to install and may require specialized repairs.
