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