Description
Alkalinity is a unit of measurement that serves to indicate the buffer capacity of the water. It measures the amount of a multitude of anions such as carbonates, bicarbonates, borates and hydroxides dissolved in water. It characterizes the buffer capacity, that is the capacity necessary to maintain the pH value of water, whether it is sea or fresh. A stable pH value is optimal for fish and invertebrates and is an important prerequisite for their well-being.
For this reason it is good to constantly monitor the KH value present in the aquarium. In the marine water aquarium the alkalinity should oscillate between 7° and 10° dKH (German degrees of carbonate), in the fresh water one it should not fall below 3° dKH with peaks of 8-10° for aquariums of fish from East Africa.
