The Velda Aqua Tests determines the quality of pond and aquarium water quickly and accurately, testing for pH, GH and KH.
Once you've tested your water, why not check out the Velda Pond Test App, where you can enter your values and get crystal clear pond diagnosis and tips for improvement from Velda, attuned to your pond situation. The test results are saved to build up a picture of how the pond is developing.
- pH Test measures the degree of acidity of fresh and salt water using a colour chart and comparator. A value above pH 8,5 will stagnate plant growth and a value less than pH 7 is harmful for your fish.
- GH Test measures the general hardness of fresh and salt water with an accuracy of 1 °GH. Values less than 8 °GH will slow down the growth of pond plants and may cause acidification, especially in winter.
- KH Test measures the carbonate hardness of fresh and salt water with an accuracy of 1 °GH. Values less than 6 °GH indicate acidification of the pond and stagnation of oxygen producing plants.
