Pool Water Selector

Water that is clean and transparent with balanced pH is the best for any pool. The ideal water source can change depending on usage and preferences as long as it is free of pollutants that can change the water’s chemistry and impact the pool’s equipment and swimmers’ health.

The standard swimming pool water quality in Australia outlines the minimum water chemistry and hygiene requirements. It covers parameters such as pH, total alkalinity, calcium hardness, chlorine, cyanuric acid, and bacteria count and sets limits to ensure safe and comfortable swimming conditions.

Water for pools is considered healthy if they adhere to the Australian Standard for swimming pool water quality. These include:

• A pH between 7.2 and 7.8
• 60 to 200 ppm of total alkalinity
• 100 to 500 ppm of calcium hardness
• 1-3 ppm of chlorine

Additionally, healthy pool water requires proper filtration, circulation and overall cleanliness.

There are three main options for swimming pool water: 

• Saltwater pools — These pools use a salt chlorine generator to produce chlorine from salt, making the water gentler on the skin and eyes. They also have a lower chlorine odour, which is great for families with kids who spend much time in the pool.
• Mineral water pools — These contain minerals that help soften the water and positively affect health.
• Freshwater pools — The water in freshwater pools is typically treated using natural products such as ozone generators or UV systems, which help to keep the water clean and clear. This is an excellent option for those who want to avoid chlorine or salty water.

Each has unique characteristics, advantages and disadvantages, depending on the pool’s location, size, usage and maintenance preferences.

There are three main options for swimming pool water: 

Excessive chlorine concentrations in swimming pools are risky because, among other health issues, they can irritate the skin, eyes and respiratory system. The level of free accessible chlorine should be maintained between 1-3 ppm and adjusted as necessary.

The choice between saltwater and freshwater pools largely depends on personal preference and maintenance requirements.  Saltwater pools are often preferred for their lower maintenance requirements and softer, more natural feel. Nevertheless, they may require more expensive equipment. Although freshwater pools sometimes cost cheaper to create and maintain, they often require more regular chemical-level monitoring and treatment.
