What are the dangers of improper pH balance in pool water?

Maintaining the proper pH balance in pool water is crucial for several reasons. An improper pH level can lead to skin and eye irritation because water that is too acidic can be harsh on the skin and eyes, while water that is too alkaline can also irritate. Additionally, incorrect pH levels can cause equipment corrosion; acidic water can erode metal components, while alkaline water can lead to scale buildup, both of which compromise the integrity and functionality of pool equipment.

Moreover, the effectiveness of sanitizers, such as chlorine, is highly dependent on the pH level. If the pH is not within the ideal range (typically 7.2 to 7.8), the sanitizer may not work effectively, increasing the risk of waterborne illnesses. Therefore, option B accurately encompasses the multiple consequences of improper pH balancing, highlighting its impact on health and equipment, as well as its influence on sanitation.
