Description: For the determination of the carbonate hardness or the alkalinity in freshwater.
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 these tests 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 approx. 100 tests.
