KH PRO – Professional Test for Carbonate Hardness (Alkalinity) Measurement in Aquariums
Carbonate hardness (KH), also known as alkalinity, is a fundamental measure of water’s buffering capacity—the ability to maintain a stable pH level. This parameter is primarily determined by bicarbonate ions, but at higher pH values other basic ions like hydroxide also contribute to alkalinity.
Regular monitoring of alkalinity is essential in all aquariums: too low alkalinity can cause dangerous pH drops harmful to fish and invertebrates. In reef aquariums, adequate alkalinity ensures vigorous coral growth, while excessive alkalinity may lead to calcium carbonate precipitation and hinder coral development.
Technical note:
In aquarium practice, carbonate hardness and alkalinity are often used interchangeably despite distinct chemical definitions.
Typical values:
-
Oceans: about 6.5 °dH
-
Marine aquariums: between 6 and 9 °dH
-
Freshwater aquariums: no less than 3 °dH (depending on species)
KH PRO is a professional alkalinity test kit with high resolution up to 0.1 °dH. The clear color change from turquoise blue to pink allows easy and reliable measurement. The kit includes a conversion table for other units like milliequivalents per liter and mmol/l.
