This Aiga MAREVA - 111044U slow release chlorine is a product that will provide your pool with a long-lasting disinfectant action, suitable for regular maintenance treatments. The 250 gram pebbles guarantee a slow release, for a long and constant chlorination over time. Chlorine has a disinfectant action, useful to prevent the formation and proliferation of bacteria, viruses, algae and various undesirable micro-organisms. The 250 g pebbles are sufficient for 20 to 30 m3 of water and are placed directly in the skimmer or diffuser. For an effective treatment, you must first make sure to bring the pH to a value between 7.2 and 7.6. At this point, it will be necessary to adjust the filtration time according to the water temperature. For example, if the water temperature is 24C, the filtration time should be increased to 12 hours. In general, a dose should be added every 7/10 days to complete the treatment of your pool (this is an indication only, as the dosage may vary according to the characteristics of each pool, the climate, the number of visitors etc.) MAREVA specializes in the manufacture and design of treatment products and equipment for in-ground pools, above-ground and self-supporting pools or public pools.
