Water Tests & Analysis

Testing your aquarium water regularly helps you better understand its balance and quickly identify an unsuitable parameter. Clear water is not necessarily water suited to fish, shrimp or plants: certain invisible substances can reach problematic concentrations.

This category brings together aquarium water tests for measuring, in particular, pH, GH, KH, nitrite (NO₂), nitrate (NO₃), phosphate (PO₄) and iron (Fe). You will find various test kits here as well as refills to renew the reagents you need.

Tests are especially important when starting up an aquarium, after introducing new animals, in the event of unusual behaviour or before adding a product intended to modify the water.

Carry out the analyses in accordance with the manufacturer's instructions and always interpret the results according to the needs of the species you keep. Measuring before you act allows you to work more precisely and to avoid unnecessary corrections or overdoses.
