The API® AMMONIA test kit measures ammonia to help prevent fish loss, as ammonia is the number one stressor and killer for tropical fish. Ammonia is released into the aquarium in the form of uneaten food, decaying organic matter, and when fish release it through their gills, urine, and waste Solid.
