The Sera NH₄/NH₃ Test Kit provides precise measurement of ammonium (NH₄) and ammonia (NH₃) levels in both freshwater and marine aquariums. These compounds are critical indicators of water quality, especially during tank cycling or in systems with high biological load. Elevated ammonia can be toxic to fish, making early detection essential for a stable aquatic environment.
