Measuring carbonate hardness (Kh) is one of the fundamental parameters to take into account when measuring water in our aquarium.
Carbonate hardness is composed of calcium and magnesium compounds with carbonic acid. This sum concentrates the acids to prevent the pH from experiencing intense variations that become a danger.
This value is measured weekly in fresh and salt water. It must have a value between 5 and 10ºdkH.
Thanks to the sera test you will be able to control the hardness of carbonates easily and effectively, with precise values.
