API Test Kit Freshwater GH & KH

Help duplicate the natural habitat of your freshwater fish and plants by testing regularly with API's GH & KH Freshwater Aquarium Test Kit. Water hardness is a measure of the dissolved mineral content of water and there are two types: general hardness (GH) and carbonate hardness (KH). The GH and KH of your aquarium water should match the natural habitat of your freshwater fish and your plants. This kit also helps you detect low KH levels, which can cause rapid and wide shifts in pH levels which can stress fish. This kit comes with a KH test bottle, a GH test bottle, instructions and two capped glass test tubes. Now, you can help provide a safe, hospitable environment for your fish, so they can stay healthy and thriving.
