PRECISION carbonate hardness / alkalinity test for marine aquariums

Measuring range: 0.1 - 20°dKH

About carbonate hardness

The carbonate hardness (KH)* or alkalinity* of a water sample characterizes the buffering capacity, i.e. the ability to maintain the pH of the water. It is largely determined by the proportion of bicarbonate ions in the water. As the pH increases, other basic ions, such as hydroxide ions, contribute to the alkalinity. Carbonate hardness should be checked in all aquariums with great regularity. If the alkalinity in the aquarium is too low, it can lead to a drop in pH (drop in acid) which can be life threatening for many fish and invertebrates. In reef tanks, sufficient carbonate hardness is essential for strong coral growth.

* In water chemistry, there are several terms to describe carrying capacity with different definitions. In aquaristics, the term "carbonate hardness" is common; however, alkalinity is measured. In this test, the two terms are used as synonyms.

The carbonate hardness specification is usually given in degrees of German hardness (°dKH). A table for converting to other common units (such as Milllival equivalence unit per liter (mval/l) or amount of substance in mmol/l) can be found on the front cover.

In the oceans, the carbonate hardness is 6.5° dKH. In the marine aquarium, the carbonate hardness should be between 6 and 9° dKH.

Measurements at unfavorable values

To increase the carbonate hardness when the values are too low, we recommend the use of Marin Carbonate MIX or Easy dKH or ELEMENTALS KH fauna in the field of sea water . Let us advise you.
