Corosex Corosex 18,7ltr / 23kg bag

Corosex granular material is used to regulate the acidity of water and dose magnesium ions into the water. Corosex granules are composed of magnesium oxide (min. 97%). Dissolving gradually, Corosex passes into water as magnesium hydroxide. In addition, free carbon dioxide contained in the water is neutralized in the intergranular space and on the surface of the granules.
