AQUAYER test pH+KH

AQUAYER test kit pH+KH for determination of pH (acidity) and KH (carbonate hardness, alkalinity) of aquarium water

pH (acidity) - the most important water parameter in the aquarium. The optimum pH for freshwater aquarium fish is 6.0-8.0, and for optimal growth of aquatic plants 6.0-7.0. It is recommended to measure the pH in the aquarium at least once a week. Also at fish transfer from one aquarium to another in order to avoid sudden pH change harmful to fishes.

KH (carbonate hardness, alkalinity) - is determined by the content of carbonates and bicarbonates in the water and affect the pH of water.

Advantages of AQUAYER test pH+KH

AQUAYER pH+KH set allows to determine not only the acidity and carbonate hardness (alkalinity) of aquarium water, but also to estimate the amount of CO2 using a special table enclosed to the test.

How to use

It is necessary to strictly follow the instructions to ensure the accuracy of the test declared by the manufacturer.

pH determination

  1. Pour 5 ml of aquarium water to the test tube
  2. Add 5 drops of pH reagent
  3. Swirl the test tube in a circular motion
  4. Compare colors in the test tube with the scale

KH determination

  1. Pour 5 ml of aquarium water to the test tube;
  2. Add KH reagent dropwise until the color changes from blue to yellow;
  3. 1 drop of KH reagent = 1 degree of carbonate hardness (alkalinity)

    (!) Swirl the test tube after each drop.

    Estimation of CO2 concentration

    Match the measured values of pH and KH of water using the enclosed table

    Recommended reading "Determination of the concentration of CO2 in the aquarium water"

    AQUAYER тест рН+КН

    (!) Over time pH of the aquarium water is reduced that causes the error in the estimation of CO2 concentration by comparison pH with KH as overestimation of the actual CO2 concentration in the aquarium water.
