In water chemistry, several terms, each with its own definition, exist to describe buffering capacity. In aquaristics, the term \"carbonate hardness\" is commonly used; however, alkalinity is measured. In this test, both terms are used interchangeably. Carbonate hardness is usually expressed in degrees German hardness (°dH).\u003c\/p\u003e\n\n \u003cp style=\"font-weight: 400;\"\u003eThe carbonate hardness should be checked regularly in all aquariums. If the alkalinity in the aquarium is too low, it can lead to a drop in the pH value (acidity drop), which is life-threatening for many fish and invertebrates. In reef aquariums, sufficient carbonate hardness is essential for vigorous coral growth. On the other hand, excessive carbonate hardness in saltwater tanks can lead to limescale precipitation and also negatively impact coral growth. In saltwater aquariums, the carbonate hardness should be between 6 and 9 °dH. In freshwater aquariums, the carbonate hardness should not fall below 3 °dH.\u003c\/p\u003e\n\n\u003cp style=\"font-weight: 400;\"\u003e The\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eTropic Marin® KH\/Alkalinity Test Professional\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eAllows you to determine the carbonate hardness of your aquarium water with an accuracy of 0.1 °dH via titration.
