Does a Mineral Pool Still Use Chlorine?

Yes, But Much Less Than a Traditional Pool 

One of the biggest misconceptions about owning a mineral pool is that it contains no chlorine at all. 

The truth is that most pools still use chlorine, but at significantly lower levels (up to 80%) than traditional chlorine pools. Instead of relying on chlorine as the primary sanitiser, systems such as Mineral Swim™ combine 100% natural Dead Sea minerals, advanced ozone purification, and a chlorination process that dramatically reduces the amount of chlorine required to keep your water safe and crystal clear.  

For many Australian families, this means enjoying all the benefits of a clean, hygienic pool without the harsh side effects commonly associated with high chlorine levels. 

Why Does a Mineral Pool Still Need Chlorine? 

Every swimming pool requires a sanitiser to eliminate bacteria, viruses, and algae. 

While the magnesium minerals in a magnesium pool provide comfort and water quality benefits, they are not designed to completely replace sanitisation. Instead, they work alongside ozone purification and low chlorine levels to create healthy swimming water. 

In a Mineral Swim™ system: 

• Ozone performs the majority of the sanitising. 

• 100% Dead Sea minerals improve water quality and swimming comfort. 

• A small amount of chlorine remains in the water to provide ongoing protection throughout the pool.  

This balanced approach delivers excellent water hygiene while greatly reducing the need for harsh chemicals. 

How Much Chlorine Does a Mineral Swim™ Pool Use? 

One of the biggest advantages of choosing a Mineral Swim™ magnesium swimming pool is the significant reduction in chlorine. 

Mineral Swim™ uses ozone purification technology that can reduce chlorine demand by up to 80%. Because ozone neutralises contaminants before chlorine is needed, the system can maintain sparkling clean water using much lower chlorine levels than a conventional pool.  

What Does Lower Chlorine Mean for Swimmers? 

Reducing chlorine doesn't just improve water chemistry. It also improves how the water feels. 

Many Mineral Swim™ owners notice: 

• Softer feeling water 

• Less dry skin after swimming 

• Reduced eye irritation 

• Less chlorine smell 

• Hair that feels healthier after swimming 

• No lingering chemical odour on towels or swimwear 

For people with sensitive skin, asthma or eczema, the lower chlorine environment can also provide a more comfortable swimming experience.  

How Mineral Swim™ Reduces Chlorine 

Unlike many traditional pool systems, Mineral Swim™ combines several technologies that work together. 

100% Dead Sea Minerals 

The naturally occurring minerals help improve water balance while providing the silky-soft feeling many people associate with a premium magnesium pool. 

Ozone Purification 

Ozone is an incredibly powerful oxidiser that neutralises organic contaminants before chlorine is needed. Once it has completed its job, it naturally reverts to oxygen, leaving no chemical residue. 

Low Chlorine Sanitisation 

A small amount of chlorine remains in the water to provide residual protection throughout the pool, ensuring safe swimming while avoiding excessive chemical exposure. 

Do All Mineral Pools Use Ozone? 

Not necessarily. While all mineral pools contain beneficial minerals, not every mineral pool includes ozone sanitation. 

The minerals in a magnesium pool are valued for improving the feel of the water and creating a more enjoyable swimming experience. However, they are not responsible for reducing chlorine usage. 

Instead, it is ozone sanitation technology that helps lower chlorine demand. Ozone is a powerful oxidiser that destroys contaminants before they consume chlorine, allowing the pool to maintain safe, hygienic water with much lower chlorine levels. 

This is one of the key differences with Mineral Swim™. The system combines 100% Dead Sea minerals with advanced ozone purification, enabling it to reduce chlorine usage by up to 80% compared to a traditional chlorine pool. The minerals enhance swimmer comfort, while the ozone performs most of the sanitising, leaving only a low level of chlorine in the water for ongoing residual protection. 

Understanding this distinction is important when comparing mineral pool systems, as the level of chlorine reduction depends on the sanitation technology used, not simply on the presence of magnesium minerals. 

Is a Mineral Pool Safer Because It Uses Less Chlorine? 

A common concern is whether lower chlorine means lower protection. 

The answer is no. 

A properly maintained mineral pool is just as hygienic as a traditional pool because sanitisation comes from the combined action of ozone purification (exclusive with Mineral Swim™)  and controlled chlorine levels. The result is water that is clean, clear and safe while being gentler on swimmers. 

Can You Convert an Existing Pool? 

Yes. 

One of the advantages of Mineral Swim™ is that many existing pools can be converted without replacing the entire pool. Whether you currently have a chlorine or saltwater pool, upgrading to a magnesium swimming pool allows you to enjoy softer water, reduced chlorine use and a more luxurious swimming experience.
