pH value measurement Ideal pH value 7.0 to 7.4. Rapid method. The first and most important step of swimming pool water care is to check the water values regularly. This check should be carried out at least once a week. We recommend 2-3 measurements per week. Caution: Not suitable for photometers. Do not touch the tablets with your fingers, as this can influence the measurement values. Pictures = symbolic illustrations.
