pH Levels

pH is an important factor in pool water chemistry as it measures the acidity or basicity of the water on a scale of 0-14, with 7 being neutral. A pH value of less than 7 indicates that the water is acidic, while a pH value greater than 7 indicates that the water is basic.

For a swimming pool, the ideal pH range is between 7.2 and 7.8. If the pH is too low (below 7.2), the water can become corrosive and damage the pool equipment and surfaces, and also cause eye and skin irritation for swimmers. If the pH is too high (above 7.8), the water can become cloudy and create scaling on pool surfaces, as well as reduce the effectiveness of chlorine as a sanitizer.

To maintain the proper pH level in a pool, the Crystal Water Monitor sensors measure the pH level over 1000 times per week and will give actions to adjust your pH by using increasers (sodium carbonate) or pH decreasers (sodium bisulfate) to bring the pH into the ideal range.
