mineral pool vs. saltwater pool

Although a traditional chlorine pool is generally the most popular option, there are many alternatives out there to choose from. Two of these options are a mineral pool system and a saltwater pool system. Both options offer unique advantages and considerations, making it difficult to decide between them.

Whether you’re a pool owner looking to upgrade or a prospective pool owner seeking guidance, I will explore both pool systems and weigh their pros and cons to help you make the right decision. Let’s dive in.

Main Takeaways

  • Mineral pool systems can provide a more enjoyable swimming experience with reduced chemical dependency, a gentler feel on the skin and eyes, and enhanced water quality.
  • Saltwater pool systems offer reduced skin and eye irritation and lower ongoing costs, and they are environmentally friendly.
  • The main differences between a mineral pool system and a saltwater system lie in the sanitation method, upfront cost, maintenance, water feel, effect on pool equipment, and availability.
  • Choosing between a mineral and a saltwater pool system depends on individual preferences, budget considerations, and maintenance capabilities.

Mineral Pool System

A mineral pool system is a type of pool that utilizes minerals to sanitize and treat the pool water. The system typically includes a mineral cartridge or dispenser that releases minerals, such as copper and silver, into the water. These minerals help inhibit the growth of algae and bacteria, reducing the need for traditional chemical sanitizers.

Pros of Mineral Pool System

  • Reduced chemical dependency: Mineral pool systems require fewer traditional chemical sanitizers, resulting in lower chlorine usage and reduced chemical odors.
  • Gentler on the skin and eyes: The mineral-treated water is often perceived as gentler, causing less skin and eye irritation than chlorine pools.
  • Enhanced water quality: Minerals can improve water clarity and give it a pleasant feel, providing a more enjoyable swimming experience.

Cons of Mineral Pool System

  • Initial cost: Mineral pool systems may cost more upfront than traditional chlorine systems.
  • Mineral buildup: Over time, minerals can accumulate on pool surfaces and equipment, requiring regular maintenance and potential scaling removal to prevent damage.
  • Compatibility: Mineral systems may not be compatible with certain pool equipment or filtration systems.

Saltwater Pool System

A saltwater pool system is another popular choice among pool owners, offering an alternative approach to water sanitization. This system utilizes a salt chlorine generator to convert salt into chlorine through a process called electrolysis. This generates a consistent and controlled level of chlorine in the pool water.

Remember, a saltwater pool system doesn’t mean it has the salinity like an ocean. It has, in fact, ten times less salt than the ocean and is great for people with asthma and skin allergies.

Pros of Saltwater Pool System

  • Reduced skin and eye irritation: Saltwater pools are known for their milder effect on the skin and eyes than traditional chlorine pools, making swimming more comfortable for individuals with sensitivities.
  • Lower ongoing costs: Saltwater pools are much more budget-friendly than chlorine pools in terms of ongoing costs.
  • Environmentally friendly: Chlorine pools give off chloramines, which emit harmful gas into the air. While saltwater pools do have some chlorine, it is definitely not at the same level as chlorine pools.

Cons of Saltwater Pool System

  • High initial cost: Installing a saltwater system can be more expensive due to the required equipment and conversion process.
  • Equipment maintenance: To ensure optimal performance, the salt cell requires periodic cleaning or replacement.
  • Corrosion: The salt present in saltwater pools can accelerate the corrosion of certain pool equipment and fixtures if not properly maintained. To combat this, use zinc anodes.

Main Differences Between Mineral and Saltwater Pools

To help you make a well-informed decision between a mineral pool system and a saltwater pool system, let’s compare the main differences across various aspects.

Sanitation Method

Mineral pools utilize minerals like copper and silver to inhibit algae and bacteria growth, reducing the need for traditional chemical sanitizers.

Saltwater pools convert salt into chlorine through a salt chlorine generator, maintaining a controlled chlorine level in the water.

Upfront Cost

As you need to purchase a mineral cartridge or dispenser, which costs around $250, a mineral pool costs more to set up than a traditional chlorine pool. However, it still costs less than a saltwater pool.

Saltwater pools typically require a higher upfront investment, as the salt chlorine generator can cost between $500 and $1,200.


Mineral pools are generally considered low maintenance. They require periodic monitoring of mineral levels and occasional replacement of mineral cartridges or replenishment of mineral additives. Water testing and balancing are still necessary to ensure proper water chemistry.

Saltwater pools also have reduced maintenance needs compared to chlorine pools. However, with that said, pool owners must regularly monitor salt and pH levels. The salt chlorine generator may also need occasional cleaning and maintenance. As with other types of pools, water testing, and balancing are still required.

Water Feel

Both mineral and saltwater pools have a softer feel on the skin. However, the minerals in the water of a mineral pool create a softer and silkier sensation on the skin than in saltwater pools. Swimmers describe the water as more gentle, luxurious-feeling, and less drying than other types of pools.

Effect on Pool Equipment

Mineral pools are less likely to cause corrosion or damage to pool surfaces, metal components, or equipment. However, there can be a risk of mineral buildup on equipment. 

Saltwater systems, especially if not properly maintained, can be more corrosive to certain metals and pool equipment. Regular inspection and maintenance are necessary to prevent any potential damage or corrosion issues.


Mineral pool systems may be less commonly available than saltwater systems. To set up a mineral pool, you may need to source mineral cartridges from specialized suppliers or manufacturers.

On the other hand, saltwater systems are more readily available and accessible compared to mineral systems. They have gained popularity in recent years, leading to a wider range of products and equipment options.

What’s Better: A Mineral or a Saltwater Pool?

Determining whether a mineral or saltwater pool is better depends on individual preferences, priorities, and specific circumstances. Both systems offer unique advantages and considerations.

A mineral pool may be better for you if:

  • You prefer a more natural swimming experience with reduced chemical dependency.
  • You would like softer water that feels gentle on the skin and hair.
  • You want a low-maintenance pool system with fewer chemical additives.

A saltwater pool may be the better option if:

  • You want a pool with continuous and consistent sanitization.
  • You prefer the convenience of generating chlorine on-site rather than adding chemicals manually.
  • You like the reduced maintenance requirements compared to traditional chlorine pools.

Ultimately, the “better” choice depends on your specific needs, preferences, and priorities. I recommend considering these factors such as costs, maintenance requirements, water sensation, potential health considerations, and the availability of equipment and supplies in your area.
