API Carbonate Hardness Test Kit Aquarium Water Test Kit

API KH Carbonate Hardness Fresh & Salt Water Aquarium Test Kit. Water hardness is the amount of dissolved mineral content in water and it comes in two types: general hardness (GH) and carbonate hardness (KH). Low KH levels can cause rapid and wide shifts in pH levels which can stress fish and cause illness or death. Test measures KH levels in tap, fresh and saltwater. Just fill a test tube with tank water, add a few drops of the test solution and wait until the water turns from orange to green. Compare results with the color chart and follow the recommendations if action needs to.
