Denitrification: Breakdown of nitrates by anaerobic bacteria into other forms.
Denitrification: The process by which nitrate is converted into nitrogen gas and released into the atmosphere. In the aquarium, denitrification is performed by anaerobic bacteria.
Denitrification - The conversion of Nitrate to nitrogen gas carried out by certain species of bacteria in Anoxic conditions.
Diatom - Microscopic organism with a hard shell that remains after the death of the organism.
Denitrification The removal of nitrate by anaerobic bacteria into nitrous oxide and then into free nitrogen gas. Used as a reliable method of keeping nitrates at a low level in the aquarium.
Encyclopedia 1.0 by Rebecca Smallwood ...
Denitrification must have occurred in all experimental treatments, because nitrate concentrations did not continue to climb throughout either the dosing (Fig. 6) or live animal (discussed in detail in Part 2 of this series) experiments.
The denitrification phase is the slowest and usually the phase that cannot be achieved by most of the filters mentioned above.
The reason for this is that in traditional filters, there's lots of water flowing thru' the filter media, ...
Denitrification: This is the process where nitrates are converted to nitrogen gas in the absence of oxygen (anaerobic conditions).
* Denitrification occurs under low aeration conditions, which is unhealthy for plant roots (they can't grow or take in nutrients without respiring). [This seems to indicate that some water flow through a substrate is good.
The opposite procedure is called denitrification and takes place in the absence of oxygen, by anaerobic bacteria (usually found in "live" rock and/or "live" sand).
Aquarists report good nitrate control in live rock systems, which, though not well understood, probably involves the denitrification of the nitrates within the interior of the rocks.
Live rock produces a more natural environment for the fish and also aids in nitrification and denitrification. This implies that the live rock is more that just a decoration, it is actually part of the filtration system.
There are a few products available which greatly speed up the denitrification process by providing the necessary bacteria in huge quantities in a bottle. All these product claim you can add fish from day one.
its quite dense and liiks alot like concrete, this rock is too dense to be useful for denitrification as the water cannot penetrate but its useful for building bases and saving cash if all live rock isn't wanted or if your stocking a very large ...
A deep sand bed is anything over 4 inches deep. You start to get anoxic (low oxygen) conditions and anearobic conditions that will aid in denitrification at around 4-5 inches.
They are also not real good for planted aquariums; the roots have a hard time thriving with the filter plants just below the gravel (although you add potted aquarium plants to aquariums with UGFs). UGF are also poor at denitrification, ...
A third group of bacteria continues the nitrification process by breaking down deadly nitrite ions into relatively harmless nitrate ions. Finally, denitrification finds a fourth group of bacteria breaking down that nitrate into free nitrogen or ...
