The carbon hardness value ( KH ) indicates the alkalinity - ie the hardness (in ° DH) of the water. The alkalinity depends on the amount of basic ions present in the water, mainly the content of carbonates.
Carbonates serve to supply corals with carbon. The carbon (carbon) contained in the bicarbonates is important for the photosynthesis of corals.
The higher the pH, the less CO2 the coral has. The correct alkalinity is very important for buffering, ie stabilization of the pH in marine aquarium.
The regular measurement of the KH content is therefore extremely important for a marine aquarium, since the correctly set KH value is necessary for stabilizing the pH as mentioned.
In a marine aquarium, a value between 7 - 10 ° dH (2.52 - 3.6 mol / l) is considered optimal.
