The carbonate hardness or alkalinity corresponds to the buffer capacity of the aquarium water and therefore determines the stability of the pH-value in the water. With our Tropic Marin KH/Alkalinity Test Kit the carbonate hardness and alkalinity can be measured with precision in dKH. The test liquids show a pronounced and obvious color change and are sufficient for approximately 100 tests. For seawater and freshwater.
