Sera water tests help you reliably monitor the most important water parameters in your aquarium and detect changes early on. Regular water analysis is particularly important for keeping fish, shrimp, plants, and filter bacteria healthy in the long term. With sera tests, key parameters such as pH, carbonate hardness, total hardness, nitrite, nitrate, ammonium/ammonia, phosphate, iron, copper, or chlorine can be specifically checked depending on the test kit.

The product range includes practical single tests for specific water parameters as well as complete test kits and test cases for more comprehensive monitoring. Compact sets covering the most important basic parameters are ideal for beginners, while larger test kits enable a more detailed analysis for freshwater aquariums, saltwater aquariums, or garden ponds. Many sera water tests are characterized by a high number of tests per kit: Depending on the test, numerous measurements are possible, resulting in a favorable price-to-use ratio.

Sera water tests are a useful addition to regular aquarium maintenance—for new setups, after water changes, in case of algae problems, unusual fish behavior, or for ongoing monitoring of stable water conditions.
