Aquarium Pharmaceuticals Aquarian Freshwater GH & KH Test Kit

Tests tap water and freshwater aquariums for general hardness (GH) and carbonate hardness (KH). Helps detect stress on fish caused by rapid pH shifts, which result from low KH levels and helps aquarists duplicate the natural habitat of their fish. KH & GH Test Instructions: What is Carbonate Hardness (KH)? Carbonate hardness (also known as alkalinity) is the measure of carbonate (CO32-) and bicarbonate (HCO3-) ion concentrations dissolved in water.

Knowing the pH of the water in your aquariums is important for a variety of reasons.  The most important is likely that most species of fish thrive within a small range of pH, GH, and KH.  If your aquarium isn’t optimized to their living conditions they will not look their best.  Knowing the amount of carbonate, bicarb, and hardness of your water will allow you to know if any small (or big) adjustments to these aquarium parameters are needed to improve the health and condition of your fish!
