API GH and KH Test Kit


The best way to keep your aquarium clean is to maintain good water quality. This will keep your fish strong and vibrant, as well as preventing disease.  Helps to buffer swings in pH that are dangerous to your fish.


API GH and KH Test Kit

How the API GH and KH Test Kit Works:

Tests aquaponic water 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. In aquaponic systems, we want to maintain a KH of at least 4º and it is safe to go as high as 18º. Use AquaBuffer to increase the KH levels in your system.
