NH3/NH4 TEST – Reagent for Measuring Ammonia and Ammonium in Freshwater and Marine Aquariums
The NH3/NH4 TEST is a specialized reagent for accurately measuring ammonia (NH3) and ammonium (NH4) levels in both freshwater and saltwater aquariums. Ammonia is a highly toxic waste product excreted by fish through gills and urine, and is a critical parameter for monitoring water quality—especially during aquarium setup or biological filter stress.
At pH values below 7, ammonia converts to ammonium (NH4), which is less toxic but still dangerous in high concentrations. This test allows precise detection of both compounds and is essential for evaluating the efficiency of the aquarium’s nitrogen cycle and the overall health of aquatic life.
Main features:
Measures both ammonia and ammonium levels
Suitable for freshwater and marine environments
Quick and reliable testing method
Critical for monitoring new tanks or overloaded systems
Prevents ammonia poisoning in fish and invertebrates
Why choose the NH3/NH4 TEST:
Detects imbalances in the biological filtration cycle
Crucial for startup and troubleshooting aquarium health
Reduces fish stress and mortality risks
Enables prompt corrective actions with bacterial additives or water changes
