LAGUNA Ca 1l Pool Water Hardness Treatment Product

Product detailed description

This product reduces water hardness, which is generally caused mainly by calcium and magnesium salts. It prevents the formation of deposits on the walls and bottom of the pool, and also binds iron and manganese ions that cause undesirable water discoloration. It is usually expressed in so-called German degrees of hardness, 1 °N = 10 mg of calcium oxide (CaO) per liter. According to these degrees, water is usually classified as very soft up to 4 °N, soft 4 - 7 °N, medium hard 7 - 14 °N, hard 14 - 21 °N, and very hard above 21 °N. If the pool is filled with hard water, calcium and magnesium salts precipitate from the water. Other impurities accumulate on these deposits, creating a suitable environment for the growth of algae, bacteria, and viruses.
