Tropic Marin KH-Test seawater

The carbonate hardness (KH) or alkalinity of a water sample characterizes the buffering capacity, ie the ability to maintain the pH value of the water. There are many terms in water chemistry to describe buffering capacity with different definitions. The term "carbonate hardness" is common in fishing; however, it is the alkalinity that is measured.

In this test, both terms are used synonymously. The reading for alkalinity is usually given in degrees of German hardness (°dH). The alkalinity should be tested regularly in all aquariums. If the alkalinity in the aquarium is too low, the pH level can drop (sudden drop in acidity) to levels that are life-threatening to many fish and invertebrates.

In reef aquariums, an adequate alkalinity level is essential for strong coral growth. On the other hand, too high an alkalinity in saltwater tanks can lead to calcium carbonate precipitation and also negatively affect coral growth. The alkalinity in saltwater aquariums should range from 6 to 9°dH. The alkalinity in freshwater aquariums should not be less than 3°dH. The Tropic Marin® KH Test Kit makes it possible to quickly determine the alkalinity of your aquarium water through ease of use and high accuracy.
