pH - (minus) granules, kg ,
USAGE: Water care product. The pH-value of the water is one of the most important factors for an optimal effect of swimming pool disinfectants. pH - (minus) granules are used to lower the pH-value and pH + (plus) granules are used to increase the pH-value. The optimal range for the pH-value is between 7.0 and 7.4. Deviations increase the necessary dosage quantities of other products, or reduce their effect. The measurement can be taken with test strips or tablets.
For private swimming pools only.
DOSAGE: Dissolve 100 g (approx. 75 ml) per 10 m³ of water volume in water and add the mixture to the pool to reduce the pH value of the pool water by approx. 0,1.
