Maintaining balanced water is a fundamental aspect of pool care, and a critical factor in achieving this balance is understanding the pH level. pH, or potential of hydrogen, measures the acidity or basicity of swimming pool water on a scale from 0 to 14, with 7 being neutral. Keeping the pH level within the recommended range, typically between 7.2 to 7.4, is crucial for the overall health of your pool.

In the context of pool chemistry, a pH below 7 indicates acidity, while above 7 suggests basic or alkaline conditions. Substances like lemon juice and vinegar are acidic, while certain soaps and stomach relief tablets are alkaline. The human eye, with an ideal pH level of around 7, can experience irritation from both acidic and alkaline substances.

Why Balanced Water Matters

Maintaining the recommended pH level is essential to prevent potential issues. Imbalances in pH levels can lead to equipment damage, compromised water quality, and discomfort to swimmers through eye and skin irritation.

Understanding the pH Impact

Anything introduced to pool water, particularly sanitizers, can influence pH levels. It's crucial to recognize the chemical characteristics of your primary sanitizer when choosing the right pH chemical for your pool.

Managing pH with Sanitizers

Acidic sanitizers, such as gas chlorine, can lower pH, potentially causing corrosion and etching of pool surfaces. On the other hand, basic sanitizers, like sodium hypochlorite, can raise pH levels, leading to cloudy water and scale buildup.

Options for pH Remediation

If your pool's pH is too low, periodic manual additions of basic chemicals like sodium bicarbonate or soda ash can raise pH and alkalinity. Conversely, if pH is too high, chemicals like muriatic acid or sodium bisulfate can be used to lower it.

Proactive pH Management

Understanding the pH of your water source is crucial for effective pool pH management. Water sources vary in pH levels and minerals, influencing the adjustment needed. Implementing a pH remediation system, regularly testing water chemistry, and making minor maintenance adjustments will create an environment for safe and enjoyable swimming in the best water quality possible.
