Description

API GH KH Test Kit will measure General Hardness & Carbonate Hardness in your aquarium.

General Hardness or GH is the measure of calcium (Ca++) and magnesium ions (Mg++) dissolved in water. General Hardness is measured with the GH Test Kit. Carbonate Hardness, also known as

KH, refers to the concentration of bicarbonate (HCO3-) and carbonate (CO3–) dissolved in water. Carbonate Hardness is measured with the KH Test Kit.

Calcium and magnesium carry a positive charge and form “ion pairs” with negatively charged ions like bicarbonate, forming calcium bicarbonate and magnesium bicarbonate; Ca(HCO3)2 & Mg(HCO3)2.

Marine reef aquarists interested in measuring the calcium level in their aquariums should use a calcium test kit made specifically for this purpose. The KH Test Kit can be used to test the carbonate hardness in saltwater aquariums.
