To maintain the optimal pH value in the pool within a range of 7.2-7.6, check the pH with a tester 2-3 times a week. The pH level above 7.6 should be lowered to the recommended values by adding the pH minus control agent. To lower the pH by 0.2, add 150 g of the control agent to 10 m3 of water. Dissolve the agent in the distribution tank of the dosing pump at a rate of 2 kg per 10 litres of water. If there is no distribution tank, pre-dissolve the product in a container and then pour the solution in portions close to the filtered water return nozzle or in several points, but not before filters. The maximum solubility of the product is about 250 g/l of water at 25°С. The recommended dosage is based on the standard properties of water. If water hardness greatly departs from the normal value, i.e. is higher than 7 mg eq/dm3, the dosage should be doubled or tripled.


Plastic buckets with a net weight of 25 kg, 13 kg, 4 kg and 1 kg.
