API KH Test Kit  

    Carbonate hardness or (KH). Can be used to determine the proper dose of pH buffers which control your pH levels. Tap water rarely provides the water conditions necessary to maintain optimal aquarium or pond water chemistry.

    Low KH can contribute to wide pH swings in your aquarium or pond. Topping off your tank with tap water can add minerals to your fish’s home, resulting in a steady increase in GH.

    It is therefore necessary to test the GH and KH frequently to monitor water quality and prevent stressful conditions from occurring.,

    Maintaining a balanced level improves the health of fish and invertebrates, so aquarium and pond water should be tested weekly to make sure it does not reach undesirable levels.

    Each kit contains 1 bottle of liquid test reagent a glass test tube with snap-tight cap, step by step instructions and information on how to correct unsafe conditions.


        Quick Facts:

    • Measures KH levels quickly.
    • For use in freshwater & seawater aquariums.
    • Ideal for all fish species tank water testing.
    • Includes all equipment required to perform the test.
    • Includes a instruction booklet.
    • Fast, easy, and accurate for precise test results.


    Directions For Testing KH:

    • Rinse a clean test tube with water to be tested.
    • Fill the test tube with 5 ml of water to be tested (to the line on the tube).
    • Holding the bottle vertically, add KH Test Solution, one drop at a time. Be sure to count the number of drops being added.
    • Cap the test tube and invert several times after each drop.
    • The test is completed when the water in the test tube, after having been shaken, turns from blue to yellow. If you have difficulty discerning the color after the first drop of test solution is added, remove the cap from the test tube and, while holding it over a white background, look down through the tube.
    • The KH value is determined by the number of drops of test solution that must be added to turn the water in the test tube bright yellow.
