Tetra will continue to help aquatic life thrive through a range of products pioneering products. Tetra Pond 6in1 Water Test Strips Coldwater Temperate 25 Test Strip Pack enables you to quickly and reliably determine the six most important water values in ponds in one simple step: dip the test strips into the water, swirl them in the water for one or two seconds, shake off any excess water and read off the most important information about the water values just 60 seconds later. The colour chart can be used to determine whether these are within the safe range. The pH, general and carbonate hardness (GH + KH), nitrite (NO2), nitrate (NO3) and chlorine (Cl2) in the garden pond water are measured. Pond inhabitants such as fish react very sensitively to excessive changes in the pH value, which impacts their well-being. The general hardness affects the vital functions of fish, while the carbonate hardness has a direct influence on the stability of the pH value (pH buffer). The test strips also measure the nitrite and nitrate values of the pond water. Nitrite is extremely harmful, even in very low concentrations, and should not be detectable in the water.Tip: with the Tetra Aquatics app you can determine water values quickly, reliably and easily using your smartphone.
