Dolamite

It is used to raise the pH of acidic waters and to remove limited amounts of iron. When water contacts the mineral, free carbon dioxide is removed, which can lead to an increase in dissolved calcium hardness. The filter function also comes into play. After a period, the mineral is exhausted and must be replenished. At least 50% of the required mineral quantity should be reserved within the system for 6 or 12 months. For easy filling, having both lower and upper connections on the tank is preferred.
