Fritz Alkalinity Test Kit biocompact 50 internal filter magnesium is present in ratherCarbonate hardness, or alkalinity (KH), is the measure of both carbonates and bicarbonates present in the water. The KH value of your water is important to know, as the carbonate hardness plays a significant role in the waters pH and the waters buffering capacity to keep that pH stable. KH naturally falls over time with the introduction of CO2 and other acids, and nitrification. Reverse osmosis water should be buffered with carbonates before use to
