Indeed, they can effectively eliminate the bacteria present in your pool. Versatile, these inorganic chlorines can be used in prevention: 70 g for 10 m3 to be diluted in a bucket at a rate of 15 g/L of water to be poured into the pool in front of the backflow, once a week. They are also useful during curative treatments, especially for shock treatment. Moreover, thanks to their properties, they will not bring any stabilizer in addition and thus the effectiveness remains the same during the use.

This treatment is used when the pH level of your pool is too high. It is also a preventive treatment in the formation of limestone deposits.
