Before you start adding chlorine to the water, it is important to have a pH value of the water between 7.2 and 7.6. You should adjust a pH value that is too high with pH-minus, and pH values that are too low with pH-plus. You must always first dissolve the pH correction agent in a bucket of lukewarm/warm water. Then, please dissolve it over the surface of the swimming water. Keep the pump/filter running. After approximately 2 hours, you can test again and make corrections if necessary. Contents: 3 kg. For lowering the pH value of swimming water. For the optimal effectiveness of the chlorine granules. Suitable for hard and soft water. We recommend adding the chlorine to the water in the evening after swimming. Never add chlorine tablets directly to the water; use a chlorine dispenser or chlorine dosing valve. If chlorine comes into direct contact with the swimming pool, the pool liner may discolour.
