For many Australian homeowners, the idea of a backyard pool is tied to relaxation, family time, and enjoying summer outdoors. But for others, traditional chlorine pools can quickly become frustrating — strong chemical smells, irritated skin, cloudy water, and the constant battle of balancing chemicals.
It’s one of the reasons more homeowners are now looking into magnesium pool conversions and low-tox pool systems as a healthier, easier-to-maintain alternative.
But while magnesium pools are growing in popularity, there’s also a lot of misinformation online about what’s actually involved in converting an existing pool.
The reality is that not every pool setup is ready for a simple switch, and choosing the wrong equipment or water system can lead to ongoing issues, unnecessary costs, and disappointing water quality.
Here’s what most pool owners don’t know before converting from chlorine to magnesium.
Why Are People Moving Away From Traditional Chlorine Pools?
Traditional chlorine pools have been the standard for decades, but many pool owners are beginning to question the long-term comfort, maintenance, and chemical exposure associated with them.
Some of the most common reasons homeowners look to convert include:
- Dry or irritated skin after swimming
- Red eyes or strong chlorine smells
- Difficulty maintaining balanced water
- Constant algae or cloudy water issues
- Wanting a healthier, lower-toxic swimming environment
- Reducing harsh chemical use around children and pets
- Improving the overall swimming experience
For many families, the goal isn’t necessarily to remove chemicals entirely; it’s about creating cleaner, softer-feeling water with fewer harsh additives and more stable water quality.
What Is a Magnesium Pool?
A magnesium pool uses mineral-based salts containing magnesium chloride and potassium chloride to help sanitise and balance pool water.
Unlike traditional chlorine pools, magnesium systems are designed to create a softer swimming experience while still maintaining safe and hygienic water conditions.
Many pool owners describe magnesium water as feeling:
- Softer on the skin
- Less drying on hair
- Gentler on the eyes
- More comfortable for sensitive skin
Magnesium pools still use sanitisation systems, but they typically rely on lower levels of harsh chemical input compared to standard chlorine setups.
Can Any Pool Be Converted to Magnesium?
In many cases, yes, but not always without adjustments.
One of the biggest misconceptions is that converting to magnesium is simply a matter of adding magnesium minerals to existing water. In reality, the condition of your current equipment and circulation system plays a major role in how successful the conversion will be.
Before converting, it’s important to assess:
- The age and condition of your chlorinator
- Pump efficiency and flow rates
- Filter condition
- Pipework and circulation
- Existing water chemistry issues
- Any signs of corrosion or scale buildup
Older systems that are already struggling with circulation or sanitation may continue having problems even after switching to magnesium. A proper assessment helps ensure the pool is actually ready for conversion rather than simply masking existing issues.
The Hidden Equipment Problems Many Pool Owners Discover
One of the most common situations pool professionals encounter is homeowners believing their water system is the problem, when in reality the equipment setup itself is outdated or incorrectly configured.
Issues like:
- Undersized pumps
- Inefficient filtration
- Poor circulation
- Old chlorinators
- Incorrectly matched equipment can all affect water clarity and mineral performance.
In many cases, converting to magnesium becomes an ideal opportunity to modernise the pool system and improve overall efficiency at the same time.
This can help:
- Reduce running costs
- Improve water clarity
- Reduce maintenance frequency
- Improve sanitation consistency
- Extend equipment lifespan
Magnesium vs Salt Pools: What’s the Difference?
This is one of the most common questions pool owners ask. While both systems use minerals and electrolysis, magnesium pools are designed to incorporate additional mineral blends that create a different water feel and swimming experience.
Traditional salt pools primarily focus on generating chlorine through salt electrolysis, whereas magnesium systems aim to create:
- Softer-feeling water
- Lower irritation
- Enhanced comfort
- More stable water balance
Many homeowners who switch from standard salt pools to magnesium systems notice a significant difference in comfort and water quality.
Is a Magnesium Pool Completely Chemical Free?
No, and any company claiming otherwise should be approached cautiously.
All safe swimming pools require proper sanitation and water management to prevent bacteria, algae, and unsafe water conditions.
A magnesium pool is better described as:
- Lower-tox
- Lower-chemical
- Gentler on the body
- More naturally balanced
Rather than being completely chemical-free.
The goal is safer, healthier water with reduced reliance on harsh chemical treatment , not eliminating sanitation.
What Does It Cost to Convert a Pool to Magnesium?
The cost of converting a pool depends on several factors, including:
- Pool size
- Existing equipment condition
- Whether upgrades are required
- Current filtration system
- Water condition
For pools with modern, compatible equipment, the process may be relatively straightforward.
For older pools, additional upgrades may be recommended to ensure the magnesium system performs properly and efficiently long-term.
While there is an upfront investment, many homeowners find the long-term benefits worthwhile due to:
- Improved comfort
- Reduced maintenance frustrations
- Better water quality
- Increased energy efficiency
- Lower ongoing chemical use
Signs Your Pool May Be Ready for a Conversion
If you’re experiencing any of the following, it may be worth considering a magnesium or low-tox pool system:
- Constant chemical balancing issues
- Strong chlorine smell
- Dry skin or irritated eyes after swimming
- Cloudy or inconsistent water quality
- Older equipment is struggling to keep up
- Rising running costs
- Ongoing algae problems
- Wanting a healthier swimming environment for your family
Why Professional Assessment Matters Before Switching
Every pool is different, and successful magnesium conversions depend heavily on the condition of the existing system.
A professional assessment can help identify:
- Whether your current equipment is compatible
- Hidden circulation or filtration problems
- Opportunities to improve energy efficiency
- Potential long-term maintenance issues
- The best conversion approach for your pool
Most importantly, it helps avoid costly mistakes that can lead to poor water quality or ongoing maintenance headaches after conversion.
Considering a Magnesium Pool Conversion?
Converting from chlorine to magnesium can dramatically improve the comfort, feel, and overall swimming experience of your pool, but only when the system is properly designed and balanced from the beginning.
At Energy Efficient Pools, we help homeowners assess their current pool setup, identify hidden equipment issues, and create healthier, more efficient swimming environments designed for long-term performance.
Whether you’re exploring magnesium conversion, upgrading outdated equipment, or looking for a lower-tox pool solution, the right setup makes all the difference.
