Aquaforest TestPro Carbonate hardness has been developed in order to quickly determine the carbonate hardness (dKH) and alkalinity (meg / L) in seawater. The alkalinity should be analyzed regularly, in conjunction with other water values such as calcium and magnesium. The recommended carbonate hardness is between 6.5 and 8.0 dKH. With this test kit you can perform between 78 and 100 tests.
