Healthy aquarium/healthy pond with conditions close to natureThe right water values are dependent on the fish stock and the plants in the aquarium/pond. Even if the water looks clear it can be contaminated. With bad values, diseases or algae can appear in the aquarium/pond. To maintain a healthy aquarium/pond with conditions close to nature it is important to check and adapt the water values regularly. For each water analysis, JBL provides water tests in the form of quick tests or colour change tests. These determine a certain value or several values in one go. With these water tests, you can recognise algae problems and negative nitrate, nitrite, potassium, magnesium values etc. Why test?The well-being of aquarium and pond dwellers and the growth of aquatic plants depend to a large extent on the KH level being kept as constant as possible. The carbonate hardness is one of the most important water values since it keeps the pH level stable. The KH should never drop below 4 °dKH.
