'''Nitrifying bacteria''' is a term used to group species of bacteria that do useful work in an aquarium in turning toxic forms of [[nitrogen]] dissolved in water (typically [[ammonia]] (NH³/NH<sup>4</sup>) and [[nitrite]] (NO²)) into other forms of less toxic nitrogen (typically [[nitrate]] NO³).<br />
<br />
==Species==<br />
''[http://microbewiki.kenyon.edu/index.php/Nitrosomonas Nitrosomonas]'' Species: These are the ones that convert ammonia (released by rotting fish or plant waste) into [[Nitrite]].<br />
<br />
''[http://microbewiki.kenyon.edu/index.php/Nitrobacter_hamburgensis Nitrobacter]'' sp.<ref>[[Dr. Tim Hovanec]] claims that it is ''Nitrospira'' sp. and not ''Nitrobacter'' that is the primary species for converting nitrite into nitrate. See [http://www.drtimsaquatics.com/Library_Presentations/SciencePapers/assets/hovanecAEM_Jan98.pdf PDF Paper].</ref> and ''[http://microbewiki.kenyon.edu/index.php/Nitrospira Nitrospira]'' Species: They convert the nitrite into nitrate. Both of these are usually present in the filter.<br />
<br />
<br />
*''Nitrosococcus'' and ''Nitrococcus'' are the main nitrifying bacteria used in salt water aquariums.<br />
<br />
==Growth Needs==<br />
*A water temperature of around {{C|20|30}}<br />
*A water ph of 7.2-8<br />
*The water must have a [[KH]] and a [[GH]] of at least {{d|6}}.<br />
*A nitrogen food source. Preferably free Ammonia (NH3)<br />
*A good supply of oxygen in the water. At least 3ppm.<br />
<br />
==Growth suppressors==<br />
*Light. Nitrifying bacteria prefer to grow and operate in the dark.<br />
*Heavy metals and chemical metal chelators or binders slow growth.<br />
*High levels of [[NH3]] (above 3ppm) suppress the bacteria's growth.<br />
*Lack of suitable surfaces to grow on. Bacteria prefer rough, high surface area surfaces. See Seachem's [[Matrix]] product.<br />
<br />
*Denitrifying Bacteria: This is the term used for a range of [[anaerobic]] bacteria that feed off oxygen from nitrate and work in conditions where there is no free oxygen to use. (In cases, they can turn nitrate back into nitrite).<br />
<br />
