The solution for a quick increase of the carbonate hardness.
The infeed of 50ml kH + Ca 1 increases the carbonate hardness by 2°kH with 100 l water.
The ideal value is abt. 10° kH. The kH-value reflects the pH-buffer volume of the water. In case of a too low kH-value, there will be the danger of a
pH-drop.
