About Fritz Ammonia Test Strips
Fritz Ammonia Test Strips are a fast and efficient way to accurately measure the total ammonia (NH3 and NH4+) levels from 0 to 8 ppm in both fresh and saltwater systems, making it useful for any aquarium environment.
Ammonia is one of the most important parameters to monitor in aquariums because any amount can be toxic to livestock if it is not addressed right away. Ammonia is commonly elevated in new tanks while establishing the beneficial biological filter. High ammonia can also be present in established aquariums from lack of maintenance, overstocking, or when the bio filter has been interrupted by medication. Ammonia can reach lethal levels very rapidly, and should be tested immediately in the case of fish illness.
