Before putting your chlorinator back into operation, make sure that the water temperature is above 15 °C and the salt content is above 2.5 kg per cubic meter, the recommended value being 5 kg. The pool water must be clear, free of algae and sediment, and its TAC, TH and pH levels must be balanced (between 7.0 and 7.2 for pH). Clean the filters and prefilters and use them according to the manufacturer’s specifications. Finally, make sure that the stabilizer level is less than 50 ppm and the free chlorine level in the pool is greater than or equal to 1 ppm.
