Florida Community Association Manager Practice Exam

What is the acceptable pH range for maintaining pool water quality?

1. 6.5-7.0

2. 7.0-7.4

3. 7.2-7.8

4. 8.0-8.5

The correct answer is: 7.2-7.8

The acceptable pH range for maintaining pool water quality is between 7.2 and 7.8. This range is critical for various reasons. A pH level within this range helps to ensure the effectiveness of chlorine and other disinfectants used in the pool, as they function optimally at a pH of around 7.4 to 7.6. Maintaining the pH within 7.2 to 7.8 also protects swimmers from skin and eye irritation. When the pH is too low (below 7.2), the water can become corrosive, potentially damaging pool equipment and surfaces, as well as causing discomfort for bathers. Conversely, if the pH is too high (above 7.8), it can lead to scaling and cloudy water, making it difficult to maintain clear and hygienic water. Overall, this pH range provides a balance between comfort for pool users and effectiveness for sanitation, making it the standard for proper pool water management.
