Although nitrate is not as directly lethal as ammonia or nitrite, over time, high levels of nitrate negatively impact fish and the aquarium environment in general. Nitrites are the most common killers of aquarium fish so they are the compounds we must guard against in the Nitrogen Cycle. It is not used in pure isolated form since it is highly unstable and decomposes into water and nitrogen, even at room temperature. Nitrites (NO2) consist of one nitrogen atom and two oxygen atoms. With rich resource and convenient transportation, we covers an area of more than 8 thousand square meters. Plants can take up and store additional nitrogen to use later if nitrogen becomes limiting.

For home cooks, a product called "pink salt" or Prague powder that combines sodium nitrites and/or nitrates with sodium chloride (salt) makes it possible to safely preserve meat for flavor and extended storage. Nitrite may also be absorbed direct from fodder such as hay if it becomes wet or mouldy. They also include materials that react chemically to oxidize combustible (burnable) materials; this means that oxygen combines chemically with the other material in a way that increases the chance of a fire or explosion. The toxicity of nitrite is dependent on chloride concentration and the acutely toxic concentration varies from less than 1 mg/L to 10 or more, depending on chloride.

Oxidation of ammonium-nitrogen (NH 4-N) Bacteria carrying out ammonia oxidation to nitrate are autotrophs (chemolithotrophs) which use reduced nitrogen species for energy (electron donor): ammonia oxidizing bacteria (AOB) use ammonia, NH 3 /NH 4 + (oxidation state -3) and nitrite oxidizing bacteria (NOB) use nitrite, NO 2-(oxidation state +3). At a higher pH, the lack of hydroniums tends to produce un-ionized ammonia. Ammonium sulfate is used to maintain or slightly lower the pH of soils. Add sufficient ammonium hydrox-ide to raise the total ammonia level to between 3 and 5 mg/L. Ammonium nitrite forms naturally in the air and can be prepared by the absorption of equal parts nitrogen dioxide and nitric oxide in aqueous ammonia.
