The alkalinity or carbonate hardness (KH) is a measure of the buffer capacity of the water and is decisive for a stable pH value in the aquarium. The alkalinity or KH should be between KH 6 and KH 8°dH in a marine aquarium. In natural seawater, the alkalinity is approx. 7.0°dH. This value is stable in the sea due to the large water mass, but in the aquarium biochemical processes can have a great influence on the carbonate hardness and change it.
Stony corals, mussels, soft corals and calcareous algae extract calcium and carbonate ions from the water during calcification and store calcium in the form of calcium carbonate. This reduces the Ca and KH values. Regular addition of Power KH+ or KH+ liquid stabilises the alkalinity and prevents the dangerous drop in acidity. Due to the different number of consumers, each aquarium has its own needs. In some cases, a well growing aquarium can ”consume” 1 KH per day. Therefore, the KH value must be checked at least once a week.
