NO3, this is a product in the nitrogen cycle. It is not toxic, though at high levels can cause some distress. In a reef tank it should be kept as low as possible, under 10ppm. Fish only tanks can generally stand 30-40ppm.
is a positively charged ion with the chemical form of NO3-, it is one of the two forms of nitrogen that is taken up by plants.
The only form in which nitrogen can be used directly by plants; a component of chemical fertilizers.
The nitrogen ion, NO3-, is derived from nitric acid and is an important source of nitrogen in fertilizers. Nitrate pollution of drinking water, shallow wells being particularly vulnerable, is of concern because infants are especially sensitive. A nitrate drinking water standard has been set under the Safe Drinking Water Act. An Environmental Protection Agency national survey of drinking water wells conducted from 1988 to 1990 indicated that 2.4% of rural domestic wells contained nitrate at or above the 10 mg/L standard. Higher rates of contamination have been found in areas of high vulnerability; for example, surveys along the upper Des Moines river indicate that 20 to 30% of wells exceed the standard.
a compound (NO3) that contains nitrogen and oxygen that comes from decomposing organic materials like manure, plants and human waste.
Chemically speaking, it is the molecule NO3, which contains a nitrogen atom, three oxygen atoms and a lone pair of electrons. It is the last stage of the aquarium nitrogen cycle and is converted from nitrites. It is harmful to aquatic animals in high concentrations.
An ion consisting of a nitrogen (N) atom and three oxygen (O) atoms. Nitrate (NO3) is an important plant nutrient (chemical needed for plant growth).

Sodium nitrate or potasium nitrate compounds used as fertilizer
Produced by Eastman Kodak starting in 1889, nitrate film was the first practical flexible-base film. Nitrate film is very flammable, becoming highly acidic (nitric acid) and increasingly flammable as it degrades. Nitrate film should be segregated from other collection materials, placed into a special explosion-proof freezer, and plans made to have it reformatted onto polyester.
This is a non-toxic compound in the nitrogen cycle. Although not a critical problem in freshwater tanks, marine tanks should be kept well below 10 ppm.
A form of nitrogen which is readily available to both aquatic and terrestrial plants as a nutrient.
Nitrogen is one of the most abundant elements. About 80 percent of the air we breath is nitrogen. It is found in the cells of all living things and is a major component of proteins. Inorganic nitrogen may exist in the free state as a gas N2, or as nitrate NO3-, nitrite NO2-, or ammonia NH3+. Organic nitrogen is found in proteins and is continually recycled by plants and animals.

Plant nutrient and inorganic fertilizer that enters water supply sources from septic systems, animal feed lots, agricultural fertilizers, manure, industrial waste waters, sanitary landfills and garbage dumps.
A corrosion inhibitor often found in traditional coolants. Nitrate imparts corrosion protection for aluminum components. Nitrate is also a decomposition product formed in the routing aging of coolants that contain nitrite inhibitors
Fertiliser consisting of sodium or potassium
(NO3_2)An important nutrient in the ocean.
Mildly toxic end product of biological filtration or the aquarium nitrogen cycle. At high levels nitrate can be stressful to fish and other aquatic organisms. In aquariums, it should be kept as low as possible. In reef tanks it should always be below 10ppm, while fish only tanks can withstand 30-40ppm. Nitrate levels can be used as a gauge to tell when a partial water change is needed.
NO3Ã, a compound that is formed when bacteria in the soil combine nitrogen with oxygen. These bacteria are different from those responsible for forming nitrites. Nitrogen in this form is very easily washed out of the soil.
a form of nitric oxide that dilates the blood vessels to the heart.
Type of drug which contains nitric acid
NO2, nitrogenous waste practically harmless to turtles but toxic to fish.
A final decomposition product of organic nitrogen compounds. A nitrogen-oxygen ion (NO3-) available as a plant nutrient and soluble in water.
Nitrate is a class of compounds called nutrients. Nutrients are needed by plants to survive and are often added to lawns and soil as fertilizer. Nitrate also occurs as a by-product from animal waste. Nitrate is a problem for water quality when levels get too high, Nitrate is the end product of the break-down of ammonia.
An ion that, while harmless in itself, can be reduced to nitrite by certain "wort spoiler" bacteria.
An important plant nutrient and type of inorganic fertilizer (most highly oxidized phase in the nitrogen cycle). In water, the major sources of nitrates are septic tanks, feed lots and fertilizers.
Present naturally in all source waters, although higher concentrations can be caused by use of fertilisers. Where necessary, nitrate levels are reduced during water treatment (ion exchange or blending with low nitrate water). See the DWI web site for information on health implications and control measures. 50 mg/l
An ion consisting of nitrogen and oxygen (NO3-). Nitrate is a plant nutrient and is very mobile in soils.
Less toxic by-product of nitrification, provides nutrients to plants.
(NO3) This is a non-toxic product of the nitrogen cycle. Although not a critical problem in freshwater tanks, reef tanks should be kept below 10 ppm.
an important nutrient for building protein in plants and animals.
An oxidized ion of nitrogen. Nitrifying bacteria can convert nitrite (NO2â€“) to nitrate in the nitrogen cycle. Sodium nitrate (NaNO3) and potassium nitrate (KNO3) are used as fertilizer. The nitrate ion is regulated by the US Environmental Protection Agency.

NO 3 - - Nitrate is the molecule which contains, one nitrogen atom, three oxygen atoms and a lone pair of electrons. It is the final stage of the nitrification process, and is oxidized from nitrites by Nitrobacter. Nitrate levels will continue to slowly climb in systems without adequate water changes, or a denitrification system. It is considered potentially harmful to aquatic animals in high concentrations.

NO3 the final product in the nitrogen cycle. It is not toxic, but can be dangerous at high levels. Nitrate is created by the oxidation of nitrite by nitrobacter bacteria. In a reef tank, nitrate levels should be kept below 10 ppm.
A nitrogen-containing compound that can exist in the atmosphere or as a dissolved gas in water. Nitrates are found in fertilizers, and human and animal wastes.
A form of nitrogen that can be absorbed by plants and contribute to growth. Nitrate may come from organic or inorganic sources. Because nitrate is not attracted to soil particles, it can readily move past the root zone of most plants and into groundwater.
An inorganic form of nitrogen important for plant growth. Nitrogen is in this stable form when oxygen is present. Nitrate often contaminates groundwater when water originates from manure pits, fertilized fields, lawns or septic systems. High levels of nitrate-nitrogen (over 10 mg/1) are dangerous to infants and expectant mothers. A concentration of nitrate-nitrogen (NO3-N) plus ammonium-nitrogen (NH4-N) of 0.3 mg/l in spring win support summer algae blooms if enough phosphorus is present.
Any chemical compound containing ONO2. These can be either organic nitrates (e.g., CH3ONO2) or inorganic nitrates (eg., ClONO2). See also nitrate ion, nitrate radical.
