To ensure optimum pH, GH and KH values in your pond or aquarium. The test set comprises three beakers for measuring pH, GH and KH values. It can help keep your fish healthy and discourage algae growth. With this set, you can accurately determine what adjustments are necessary to return your pond water to its optimum condition.
Usage instructions for pH testing:

• 1. Rinse out the test beaker several times with the water sample and then add 5 ml of pond water to the beaker.
• 2. Add five drops of the pH test liquid and shake gently to mix it with the water.
• 3. Place the test beaker against the colour chart and determine the value by comparing the colours.
• 4. Rinse the test beaker thoroughly after use.

Usage instructions for GH testing:
• 1. Rinse out the test beaker several times with the water sample and then add 5 ml of pond water to the beaker.
• 2. Hold the dropper vertically and add the contents to the test beaker a drop at a time while shaking the test beaker, until the colour changes from red to green. Count the number of drops; one drop corresponds to one degree of total hardness.
• 3. Rinse the test beaker thoroughly after use.

Usage instructions for KH testing:
• 1. Rinse out the test beaker several times with the water sample and then add 5 ml of pond water to the beaker.
• 2. Hold the dropper vertically and add the contents to the test beaker a drop at a time while shaking the test beaker, until the colour changes from blue to yellow. Count the number of drops; one drop corresponds to one degree of carbonate hardness.
• 3. Rinse the test beaker thoroughly after use.
