Maintaining proper water chemistry in a swimming pool is essential for swimmer safety and equipment longevity. One critical aspect of this balance is the pH level. A pH that is too low, meaning the water is acidic, can cause corrosion of pool surfaces and equipment, as well as irritation to swimmers’ skin and eyes. Conversely, a pH that is too high can lead to scaling and cloudy water, reducing the effectiveness of sanitizers like chlorine. Therefore, understanding how to raise a pool’s pH when it falls below the ideal range of 7.2 to 7.8 is crucial for responsible pool ownership.
Addressing low pH is vital because acidic water aggressively seeks to balance itself by drawing minerals from pool surfaces and components. This can lead to etching of plaster, dissolving of grout, and corrosion of metal parts like ladders, railings, and pump components. Beyond the expensive repairs that can result from neglecting low pH, swimmer discomfort is a significant concern. Acidic water can irritate eyes, causing burning and redness, and can also dry out skin, leading to itching and irritation. Historically, monitoring and adjusting pH levels were less precise, relying on less accurate test kits and less readily available chemical solutions. Modern testing and treatment options offer pool owners more precise control over water chemistry, improving safety and extending the life of their pool.
