Ammonia poisoning is a common fish disease in new aquariums, especially when immediately stocked to full capacity. Ideally, the level of ammonia (NH3) and ammonium compounds (i.e. those containing NH4+) in fish tanks should be zero. Although trace amounts are generally harmless, they can still lead to problems over time. Understanding the nitrogen cycle is essential for the keeping of any aquatic life. The source of ammonia in fish tanks is fish's excretion. Fish excrete ammonia as a nitrogenous waste product. A build-up of ammonia in the fish tank leads to ammonia poisoning. Species of ammonia-oxidizing bacteria (AOB) can break down the ammonia and convert it to other, less toxic, nitrogen products. Two examples of AOB are Nitrosospira and Nitrosomonas. The amount of ammonia present is usually accompanied by a rise in pH. As ammonia is a base, it is stabilized by acidic water. It can cause damage to the gills at a level as small as 0.25 mg/L.
