Are Fibreglass Pools Compatible With Mineral Water Systems?

As homeowners seek alternative options for pool sanitisation and maintenance, mineral water systems have gained popularity due to their eco-friendly and low-chemical nature. However, when it comes to fibreglass pools, there are concerns about compatibility with mineral water systems. In this comprehensive blog post, we will delve into the topic and explore the compatibility of fibreglass pools with mineral water systems in greater detail. We will address common misconceptions, provide valuable insights, and offer an extensive guide for pool owners considering this combination.

Understanding Mineral Water Systems


Mineral water systems, also known as mineral sanitisers or mineral ionisation systems, are innovative alternatives to traditional chlorine-based pool sanitisation methods. These systems utilise a combination of natural minerals, such as copper and silver, to control algae and bacteria growth in the pool water.

The minerals are released into the water through a dedicated chamber or cartridge, and they work by disrupting the cell structure of microorganisms, effectively inhibiting their growth. Mineral water systems offer several advantages, including reduced chemical usage, lower chlorine levels, and a more natural swimming experience.

Is The Cost Comparable?

In terms of cost, mineral sanitisation systems may differ from traditional chlorine and salt systems. While the initial investment for a mineral sanitisation system can be higher, as it typically requires the purchase of a mineral chamber or cartridge, the long-term costs can be more affordable. Mineral systems often require fewer chemical additions and maintenance, resulting in potential savings over time. Additionally, mineral sanitisation systems offer the advantage of reduced chlorine dependency, which can lead to lower chemical costs. However, it’s important to consider the specific brand, model, and maintenance requirements of the mineral system when comparing costs. Consulting with local pool professionals or suppliers in Australia can provide more accurate information on the cost comparison between mineral sanitisation, chlorine, and salt systems.

The Myth of Incompatibility

One of the most prevalent misconceptions is that pools made by fibreglasspoolsperth are not compatible with mineral water systems. Some pool owners believe that the minerals in the water may cause discolouration or damage to the pool surface. However, this is largely a myth.

Fibreglass pools are manufactured with a gel coat finish that acts as a protective layer. This gel coat is specifically designed to withstand exposure to chemicals and minerals commonly found in pool water. When properly installed and maintained, fibreglass pools can safely accommodate mineral water systems without any adverse effects on the pool surface.

Manufacturer Recommendations and Warranties

To ensure the longevity and performance of your fibreglass pool, it is crucial to follow the manufacturer’s guidelines and recommendations regarding pool water chemistry and maintenance. While most reputable fibreglass pool manufacturers do not specifically exclude the use of mineral water systems, they may provide guidelines for maintaining the proper chemical balance and water parameters to prevent any potential issues.

It is important to thoroughly review the manufacturer’s recommendations and warranty information to understand any specific requirements or limitations when using a mineral water system in conjunction with your fibreglass pool. Adhering to these guidelines will help protect your investment and ensure that the pool remains in optimal condition.

Monitoring Water Balance


Maintaining proper water balance is essential for the overall health of your fibreglass pool, regardless of the sanitisation method used. This includes monitoring pH levels, alkalinity, calcium hardness, and other factors that contribute to water chemistry. With mineral water systems, it is especially important to regularly test and adjust the water balance to ensure the minerals are effectively dispersed and the pool remains clear and algae-free.

Consulting with a pool professional or utilising water testing kits can help you accurately measure and maintain the optimal water balance. By proactively managing the water chemistry, you can enjoy the benefits of a mineral water system while safeguarding the integrity of your fibreglass pool.

Regular Maintenance and Cleaning

Proper maintenance and cleaning routines are crucial for any swimming pool, and fibreglass pools are no exception. Regular brushing and vacuuming will help prevent algae and mineral build-up on the pool surface. Additionally, checking and cleaning the mineral water system’s chamber or cartridge, as per the manufacturer’s instructions, will ensure optimal performance and prevent any blockages.

By implementing a routine maintenance schedule, including water testing, cleaning, and equipment maintenance, you can keep your fibreglass pool and mineral water system running smoothly for years to come.

Consultation with Pool Professionals

If you have concerns or questions about the compatibility of a mineral water system with your fibreglass pool, it is advisable to consult with pool professionals who have expertise in both fibreglass pool installations and mineral water systems. They can provide personalised advice based on your specific pool configuration, water conditions, and preferences.

A pool professional can evaluate your pool’s current state, assess the feasibility of incorporating a mineral water system, and provide recommendations tailored to your needs. Their experience and knowledge will help alleviate any concerns and ensure a successful integration of the mineral water system with your fibreglass pool.



Fibreglass pools are indeed compatible with mineral water systems, dispelling the myth that suggests otherwise. With proper installation, maintenance, and adherence to manufacturer guidelines, homeowners can enjoy the benefits of mineral water systems while reaping the advantages of a durable and low-maintenance fibreglass pool.

By understanding the fundamentals of mineral water systems, monitoring water balance, practising regular maintenance, and seeking guidance from pool professionals, you can confidently explore the combination of a fibreglass pool and a mineral water system, creating a harmonious and environmentally friendly swimming experience in your backyard oasis.

Remember, always consult with professionals, follow manufacturer recommendations, and establish a diligent maintenance routine to ensure the optimal compatibility and performance of your fibreglass pool and mineral water system. With careful consideration and proper care, you can enjoy a safe, crystal-clear, and refreshing swimming pool experience with the benefits of a mineral water system in your fibreglass pool.

In conclusion, the compatibility of fibreglass pools with mineral water systems is well-established. By dispelling misconceptions, understanding manufacturer recommendations, monitoring water balance, practising regular maintenance, and seeking professional guidance, you can confidently embrace the combination of a fibreglass pool and a mineral water system. With this powerful combination, you can create a beautiful and environmentally friendly swimming environment that enhances your pool experience while reducing the reliance on harsh chemicals. Enjoy the benefits of a low-chemical, low-maintenance pool and immerse yourself in a healthy and refreshing oasis right in your own backyard.
