Self-diagnostic and error messages
Ammonia is often an excellent indication of the presence of animal or plant microbiological decay. It is tested in fish farms both in fresh as well as salt water tanks due to the damaging effects of its toxic nature. Its presence in rivers and reservoirs normally points to agriculture and/or civil pollutants. Ammonia is tested among others in lakes, rivers, potable water, boiler feed water, sewage, industrial and waste water.
