Wondering what a mineral pool is and whether it suits your backyard? Learn how mineral pools work, their benefits for sensitive skin, running costs and how to convert your existing pool.
If you’ve been researching pool options or considering an alternative to traditional chlorine systems, you’ve probably encountered the term “mineral pool.” But what exactly is a mineral pool, and is it right for your backyard? This comprehensive guide covers everything you need to know about mineral pool systems.
What is a Mineral Pool?
A mineral pool is a swimming pool that uses a combination of minerals – typically magnesium, potassium, and sometimes other elements – to sanitise and soften the water. While these pools still use some chlorine or alternative sanitisers, they require significantly less than traditional chlorine pools.
Think of it as a hybrid system: you get the sanitising power of chlorine (or an alternative like Liquid Lithium) combined with the therapeutic benefits and softer water feel of natural minerals.
The Key Minerals
Magnesium: The star player in most mineral pool systems
- Softens water naturally
- Therapeutic benefits for skin and muscles
- Helps maintain pH balance
- Mild natural sanitiser
Potassium: Often paired with magnesium
- Supports chlorine efficiency
- Helps prevent algae growth
- Contributes to water softness
Other minerals: Some systems include trace minerals like boron, selenium, or silver for additional benefits.
Benefits of Mineral Pools
Why are more and more Australian pool owners choosing mineral systems? The advantages are compelling:
Softer, Silkier Water
The most immediately noticeable benefit is the water feel. Mineral pool water has a distinctly soft, silky texture that’s gentle on skin, hair, and eyes. It feels less “chemical” and more natural – almost like bathing in spring water.
What this means for you:
- Less red, irritated eyes
- Softer skin after swimming
- Hair that’s less dry and brittle
- A more pleasant swimming experience overall
Reduced Chemical Usage
Mineral pools typically require 30-50% less chlorine than traditional systems. This translates to:
- Lower ongoing chemical costs
- Reduced chemical handling and storage
- Less chlorine odour around your pool
- Fewer harsh chemical reactions
For Australian families conscious of both budgets and environmental impact, this reduction is significant.
Therapeutic Benefits
The magnesium in mineral pools offers genuine health benefits. Many users report:
- Muscle relaxation and reduced soreness
- Relief from minor aches and pains
- Improved skin condition (especially for dry or sensitive skin)
- Better sleep after evening swims
While not a replacement for medical treatment, these benefits are a welcome bonus to pool ownership.
Gentler on Pool Surfaces and Equipment
Lower chlorine levels mean less wear and tear on:
- Pool liners and surfaces
- Swimwear and pool toys
- Pool equipment and fittings
- Surrounding landscaping
Your pool investment lasts longer with less maintenance and fewer repairs.
Better for Sensitive Skin
If you or family members have:
- Eczema or psoriasis
- Chlorine sensitivity
- Dry or sensitive skin
- Respiratory sensitivities
Mineral pools offer a more comfortable swimming experience. The lower chlorine levels and soothing minerals make a noticeable difference.
Mineral Pools vs. Traditional Chlorine Pools
Let’s look at the key differences:
| Aspect | Traditional Chlorine Pool | Mineral Pool |
| Water feel | Can be harsh, drying | Soft, silky, gentle |
| Chlorine usage | High (100%) | Low (30-50% of traditional) |
| Chemical smell | Often noticeable | Minimal to none |
| Initial cost | Lower | Moderate (equipment costs) |
| Running costs | Higher chemical costs | Lower chemical costs |
| Maintenance | Standard | Slightly different routine |
| Health benefits | Basic sanitation | Added therapeutic benefits |
| Environmental impact | Higher chemical usage | Reduced chemical usage |
What Mineral Pools Are NOT
To avoid confusion, let’s clarify some common misconceptions:
Not Completely Chlorine-Free
While mineral pools can use less chlorine, all pools still require some form of sanitiser to meet safety standards. They’re “low chlorine,” not “no chlorine.”
Exception: Some mineral systems can be paired with alternative sanitisers like Ozone or Liquid Lithium for an even gentler approach.
Mineral pools still require regular:
- Water testing and balancing
- Filter cleaning
- Mineral cartridge replacement (typically every 3-6 months)
- Occasional shocking or algae treatment
The maintenance is often easier and less frequent, but not eliminated entirely.
While minerals offer genuine benefits, they work best as part of a proper maintenance routine. Neglect your pool, and you’ll still face problems regardless of the system type.
Is a Mineral Pool Right for You?
Mineral pools are an excellent choice for many Australian pool owners, but they’re not for everyone. Consider these factors:
You’re a Good Candidate If:
- You or family members have sensitive skin or chlorine reactions
- You want a more natural swimming experience
- You’re willing to invest moderately upfront for long-term savings
- You appreciate the therapeutic benefits of magnesium
- You want to reduce chemical usage
- You prefer softer, more pleasant water
You Might Prefer Traditional Systems If:
- You’re on a very tight budget (upfront costs are higher)
- You have extremely high bather loads regularly (commercial settings)
- You prefer the familiar feel of traditional pool water
- Local pool service providers lack mineral system expertise
Converting Your Existing Pool to Minerals
Already have a pool? Good news – converting to a mineral system is straightforward and doesn’t require rebuilding your pool.
Basic conversion process:
- Install a mineral system (cartridge-based or mineral salt)
- Balance your water chemistry
- Add minerals according to system specifications
- Adjust chlorine generation or manual addition down
- Monitor and maintain as recommended
Most conversions can be completed in a day, and you’ll notice the difference within a week.
Cost: Expect to invest $600-$1,500 for a quality mineral system, depending on pool size and brand. This typically pays for itself within 2-3 years through reduced chemical costs.

Maintaining Your Mineral Pool
Mineral pool maintenance is similar to traditional pools with a few key differences:
Weekly tasks:
- Test pH, alkalinity, and sanitiser levels
- Check mineral levels (monthly)
- Clean skimmer and pump baskets
- Backwash or clean filter as needed
Monthly tasks:
- Test calcium hardness
- Check mineral cartridge (replace as needed)
- Shock if required
Quarterly tasks:
- Deep clean filter
- Full water chemistry check
Mineral Pools and the Australian Climate
Mineral systems work beautifully in Australian conditions:
Hot climates: Minerals help maintain balance despite high evaporation and UV exposure
Coastal areas: Lower salt content (if using mineral salts) means less corrosion than traditional salt systems
Varied conditions: The natural buffering effect of minerals helps maintain stability through seasonal changes

The Future of Pool Sanitation
Mineral pools represent a shift toward more natural, sustainable, and user-friendly pool systems. As more Australians experience the benefits of softer water, reduced chemicals, and therapeutic minerals, adoption continues to grow.
Combined with modern liquid pool care products like those from PoolFlow, mineral pools offer the best of both worlds: effective sanitation with a dramatically improved swimming experience.
Making Your Decision
Choosing a pool system is a significant decision. Here’s what to consider:
- Talk to mineral pool owners: First-hand experiences provide invaluable insights
- Calculate long-term costs: Include initial investment, ongoing chemicals, and maintenance
- Consider your needs: Skin sensitivity, usage patterns, and maintenance preferences
- Research systems: Not all mineral systems are created equal
- Find local support: Ensure you can get service and products locally
