To promote mixing, feed the product directly into the tank near the water outlets or skimmers. Preventive treatment is recommended: add the product directly to the empty tub following the directions on the package. After filling the pool, add 250 grams of product for every 10 m³ of water to lower the pH by about 0.1 ppm. Repeat this treatment whenever a change in pH is detected to maintain the desired value. If pH values are particularly high, increase dosages following the specific directions. As a maintenance treatment, dose the product according to the instructions on the package to ensure optimal water pH. Carry out treatments preferably without the presence of bathers in the pool. These dosages are indicative and can be changed according to the technical characteristics of each pool and various climatic conditions
