This Aga MAREVA Chlorine Cleaning Pack combines the essential shock duo of slow chlorine / fast chlorine with a versatile anti-algae: everything you need to have a pool that is not only hygienic but also clear and crystal-clear. First of all, you are provided with the minimum necessary to have a correctly disinfected pool: slow chlorine and fast chlorine. In fact, you need a regular maintenance product, but also another more powerful shock treatment to be poured in a punctual way, 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 will be ideal to eliminate all bacteria, impurities and other micro-organisms in the water. Then add the multifunctional anti-algae: it is an anti-algae, anti-lime, anti-rust; but it is also a clarifier (brings together dirt particles such as organic matter brought by users, plants or sand so that they are then stopped by the filter) and a pH stabiliser (extremely useful, a key parameter for a healthy pool). It is the ideal complement to your chlorine, bromine or active oxygen disinfectant, as it considerably improves the effectiveness of the disinfectant and prolongs its action. The combination of this product with your disinfectant will bring you comfort, savings and peace of mind. Indeed, by using this anti-algae, you will be able to reduce the doses of your main disinfectant which will also improve your bathing comfort since this product contains less chlorine, which is appreciable when you consider the unpleasant chloric odors.
