A number of medications and water treatments are used in this way. Salt is the most effective bath treatment, and is used to eliminate ciliated protozoan parasites (including ich in small fish); also used to curb the absorption of nitrite, and to reduce the osmotic pressure exerted by fresh-water on any hole in the skin or gill.
Some systems incorporate bacteria capable of converting nitrates into nitrogen gas. [6] Accumulation of toxic ammonia from decomposing wastes is the largest cause of fish mortality in new, poorly maintained, or overloaded aquariums. [7] In the artificial environment of the aquarium, the nitrogen cycle effectively ends with the production of ...
As a preservative and color fixative, with or without sodium nitrate, in smoked, cured sablefish, smoked, cured salmon, and smoked, cured shad so that the level of sodium nitrite does not exceed 200 parts per million and the level of sodium nitrate does not exceed 500 parts per million in the finished product."

Nitrates affect the nitrate‐nitrite‐nitric oxide pathway, in which nitrates are recycled in blood and tissue to produce nitric oxide — an important molecule for vascular health and blood flow.
That said, if you use nitrates for angina ... (four or more cups per day) and the lowest amount (zero cups per day). ... and includes protein sources such as fish, poultry, dairy products and eggs ...
As an added measure, a protein skimmer is used to remove some of the dissolved organic compounds before they break down into ammonia, although skimmers do not remove ammonia from fish urea. The typical rule of thumb is to use from 1-2 lb (0.45 to 0.9 kg) of live rock per gallon (US) (3.7 liters) of aquarium water depending on the density of the ...
All RAS relies on biofiltration to convert ammonia (NH 4 + and NH 3) excreted by the fish into nitrate. [4] Ammonia is a waste product of fish metabolism and high concentrations (>.02 mg/L) are toxic to most finfish. [5] Nitrifying bacteria are chemoautotrophs that convert ammonia into nitrite (NO 2 −) then nitrate (NO 3 −).
In freshwater or estuarine systems close to land, nitrate can reach concentrations that are lethal to fish. While nitrate is much less toxic than ammonia, [20] levels over 30 ppm of nitrate can inhibit growth, impair the immune system and cause stress in some aquatic species. [21] Nitrate toxicity remains a subject of debate. [22]
