This Aga MAREVA chlorine cleaning pack combines the essential shock duo of slow chlorine / fast chlorine with a clarifying cartridge: everything you need to have a pool that is not only hygienic but also crystal clear. You are provided with the essential minimum for a correctly disinfected pool: slow chlorine and fast chlorine. Indeed, you need a regular maintenance product, but also another more powerful shock treatment to pour punctually, and this even if your water is apparently beautiful. Indeed, the shock treatment is essential for it to remain healthy. Slow Chlorine will effectively disinfect your water on a constant basis, once a week. Rapid Chlorine 60 is a shock treatment with a powerful disinfecting action, to be poured once a month, which aims to fight against the habituation effect of bacteria to slow chlorine. The 250 g pebbles are sufficient for 20 to 30 m3 of water and are placed directly in the skimmer or diffuser. This combination is ideal for removing all bacteria, algae, impurities and other micro-organisms from the water. However, the clarifier cartridge is the final key product that will make your water truly crystal clear, as there is often a large residue of sand and other micro-particles in the water. These cartridges, with their highly active flocculating agents, will capture the finest particles and boost the efficiency of your sand filter. For perfectly healthy water that is clear to the naked eye!
