The blocks of long lasting chlorine are highly concentrated (available chlorine 84% minimum) and make permanent chlorination of the pools possible. Their use has no effect on the pH, does not clog the filters and does not cause cloudiness in the water.
1 block (200 g) for 40 Cb.m. every 5 days. Partially or totally dissolved, the block of chlorine carries out chlorination for 5 days. Place the block in the skimmer basket of the pools or in a chlorine dispersal float. The dosages given are approximate. It is advisable to regularly check the pH as well as the chlorine level and to adjust them if necessary. The pH should be kept about 7.2. The chlorine level should be between 0.5 and 2 ppm
