Overview
The alkalinity should be tested in all aquariums with great regularity. If the alkalinity in the aquarium is too low, the pH value can sink (sudden drop in acidity) to a level which is life-threatening for many fish and invertebrates. In reef aquariums, an adequate alkalinity level is essential for strong coral growth. On the other hand, an overly high alkalinity in saltwater tanks can lead to calcium carbonate precipitates and also have a negative impact on coral growth. The alkalinity in saltwater aquariums should range from 6 to 9 °dH. The alkalinity in freshwater aquariums should not fall below 3 °dH.
The Tropic Marin KH/Alkalinity-Test Professional is a high resolution test kit for the determination of the alkalinity with a resolution of up to 0.1 °dH per titration, including a conversion table to other units. Easily recognizable colour change from turquoise blue to pink.
