222 > FOR GREATER COMFORT For the comfort of bathers, the pH of the swimming pool must be kept between 7.0 and 7.6: • Below this, the water is aggressive. • Above this, larger doses of disinfectant are needed to maintain healthy water and combat the growth of algae. • The ideal pH for the swimming pool water is also the average pH of the human body, and more especially the blood, which is between 7.35 and 7.45. > SAFE, AUTO-ADAPTIVE OPERATION Depending on the value measured by the sensor, Zodiac® pH regulation systems automatically adjust the pH of the swimming pool up or down, using a peristaltic dosing pump. The dosing time depends on the difference between the pH of the swimming pool and the ideal pH (set point value). The water balance in the swimming pool is maintained at the desired value without taking any action. Zodiac® pH regulation systems are equipped with an exclusive overdosing safety device (called 'OFA') to prevent excessive injection. The safety device is adjustable and operates in 3 steps to determine whether or not it is necessary to inject correcting product.

For optimal water balance, it includes a function to adjust injection cycles depending on the total alkalinity (TAC) of the water. A choice of 3 settings is available: DID YOU KNOW? The pH must be controlled and adjusted, whatever the disinfection system used. As a result, Zodiac pH regulation systems can be used in all types of pools.
