Adjusting the pH value with Pool Professional

The pH value is the most important factor in pool water maintenance. A correctly adjusted pH value between 7.0 and 7.4 (ideally at 7.2) is the basic requirement for clean pool water. Influences such as water temperature, bathing frequency or dirt input change the pH value in the pool water. Add pH-Minus (pH reducer) if the pH is above 7.4. After adjusting the pH value, let the filter system run for at least 24 hours so that the pool water is optimally mixed.
