Water test

A healthy aquarium starts with stable, clean water. With the right water tests, you can keep track of the most important water parameters at all times and react quickly before problems arise. In this category, you'll find a wide selection of test strips, drop tests, and digital meters for reliable water analysis in your aquarium.

Whether it's pH value, nitrite (NO₂), nitrate (NO₃), ammonium (NH₄), phosphate (PO₄) or total hardness (GH/KH) – our tests help you monitor the biological balance in the tank and create optimal living conditions for fish, shrimp and plants.
