This Mareva pack includes 5kg calcium hypochlorite granules and 5L Reva-out anti-limescale. These complementary products are essential for the good health of your pool. On the one hand, these granules have a great disinfection capacity, these unstabilized chlorines have qualities similar to chlorine. Indeed, they can effectively eliminate the bacteria present in your pool. Versatile, these inorganic chlorines can be used in prevention: 70 g for 10 m3 to be diluted in a bucket at a rate of 15 g/L of water to be poured into the pool in front of the backflow, once a week. They are also useful during curative treatments, especially for shock treatment. Moreover, thanks to their properties, they will not bring any stabilizer in addition and thus the effectiveness remains the same during the use. This is why it is recommended to use these products when the stabilizer level reaches or exceeds 75mg/l. On the other hand, Reva-out anti-limescale is an inhibitor and complexing agent for metal ions, calcium and magnesium. It prevents limescale deposits in hard (> 25 F) and heated water. MAREVA specializes in the manufacture and design of treatment products and equipment for in-ground pools, above-ground pools, self-supporting pools and public pools. Today, it is one of the European leaders in pool treatment products and the second largest producer of P.H.M.B (PolyHexaMethyleneBiguanide) which is a chlorine-free disinfectant.
