With the Aqua Tests from Velda, the quality of pond and aquarium water can be determined quickly and accurately.

  • pH Test measures the acidity of fresh and salt water using the color scale and comparator. A pH above 8.5 stagnates plant growth and a value below 7 is harmful to fish.
  • GH Test measures the joint hardness of freshwater with an accuracy of 1 °DH. A GH value less than 8 °DH stagnates plant growth and can cause acidification especially in winter.
  • KH Test measures the carbonate hardness of fresh and salt water with an accuracy of 1 °DH. A KH value less than 6 °DH indicates acidification and inhibits the growth of oxygen plants.
