Question

How does the nitrogen cycle control the quality of water within a aquarium and what could cause an imbalance (build of toxic chemicals such as ammonium).​

Answer 1

Step-by-step explanation:

Ammonia is removed from an aquarium system through the use of a biofilter. The biofilter provides a substrate on which nitrifying bacteria grow. These nitrifying bacteria consume ammonia and produce nitrite, which is also toxic to fish. Other nitrifying bacteria in the biofilter consume nitrite and produce nitrate.
