Liquid testing

9 products

Liquid aquarium tests offer maximum precision in controlling water parameters, essential for maintaining a stable and healthy environment.

Thanks to drop reagents, liquid tests allow for accurate measurement of fundamental values such as pH, KH, GH, ammonia (NH₃/NH₄⁺), nitrites (NO₂⁻), nitrates (NO₃⁻), phosphates (PO₄³⁻), calcium (Ca), and magnesium (Mg). They are essential tools for both freshwater aquariums and marine reef tanks.

Reagent kits are easy to use: simply add a few drops of reagent to the water sample and compare the color with the included scale. This allows for quick detection of any imbalances and timely intervention.

For details on measured parameters, precision, and the number of tests that can be performed, consult the product sheets.

Tip: perform liquid tests regularly, especially in the first few weeks after setting up the tank or when introducing new fish and corals.
