Api Gh/kh Hardness Test Kit



When keeping freshwater fish and plants, the general hardness (GH) and carbonate hardness (KH) of aquarium water should match their natural habitat. The API® GH & KH TEST KIT helps you duplicate the natural habitat of your fish to prevent stress, keeping them healthy!


API® GH/KH Test Kit Contains 2 test bottles, easy-to-ready instructions, and glass test tubes. *No colour chart is included on the GH/KH test kit. This is because you add drops till you achieve the colour indicated in the instructions. The number of drops added compared to the chart in the instructions will give you your results.
