      Professional drop test kit for determining pH, KH, GH, NH4, NO2, NO3, and PO4 in pond water.

      Application and Dosage
      Application
      Check water parameters regularly, especially when introducing new fish, starting a new filter, or if any abnormalities occur.
      Dosage
      To analyze the water parameters, fill the test tube with a water sample and add the respective test solution according to the instructions. After the prescribed waiting time, compare the color of the sample with the enclosed color chart and read the corresponding value. Perform the tests regularly, especially after water changes or if there are issues with water quality. This allows imbalances to be detected at an early stage and measures to be taken to ensure the well-being of the fish.
