The Tropic Marin NH4+/NH3 Test is a high-precision water testing kit designed to determine the concentration of ammonium (NH4+) and ammonia (NH3) in freshwater and marine aquariums.
Ammonia is one of the most toxic compounds in aquatic systems and can quickly become dangerous to fish, corals, and other aquarium inhabitants. Regular testing helps identify filtration issues, monitor the nitrogen cycle, and prevent harmful ammonia spikes before they affect livestock.
The test kit offers reliable results and is particularly useful during aquarium start-up, after introducing new livestock, or whenever biological filtration performance needs to be assessed.
Suitable for reef aquariums, fish-only marine systems, freshwater aquariums, and quarantine tanks.
