Aerobic is an adjective term meaning "requires oxygen". Many organisms use aerobic processes to produce energy on the cellular level.
Aerobic A term used to describe an organism that needs oxygen to survive.
Airstone A device that attaches to the air pump to create various bubble effects.
Aerobic - Existing or active in the presence of free oxygen.
Air Pump - A small electric pump, usually of the diaphragm type, used to deliver air to an aquarium.
Aerobic: Living with oxygen.
Aragonite: This composes the calcium carbonate skeletons of reef coral and some shells.
Aerobic: A term used to describe an organism that needs oxygen to survive.
Africans: Refers to freshwater cichlids from Africa. These fish come from the very hard, slightly salty water of the rift lakes.
aerobic
Describes an organism or process that consumes oxygen to function.
Anaerobic: A lack of oxygen. Anaerobic zones in an aquarium are areas where no oxygen is present such as inside live rock or under sand or gravel. Anaerobic bacteria live in these areas where they transform nitrate into nitrogen gas.
Anaerobic Bacteria
This is bacteria that can live without the presence of oxygen, or bacteria that does not require oxygen.
Anaerobic
Basically, a lack of oxygen. Anaerobic zones in an aquarium are areas where no oxygen is present such as inside live rock or under gravel.
Anaerobic
The term used to describe a biological process which occurs without the need for oxygen. Often used to describe types of bacteria and bacteriological processes such as denitrification.
Aerobic Living with oxygen.

· Aerobic = the ones that need atmospheric air to live, reproduce, function and thrive
· Akaryotic = cells without nuclei
· Algae (sin. alga) = Gk word for plants that occur in aquatic environments ...
*Good anaerobic filtration via live rock, live sand, or mud filtration.
*Plant refugiums and or good plant and green algae growth in the aquarium.
So, whilst anaerobic areas and the bacterial strains therein are beneficial to nitrogenous waste levels, there is a degree of risk in their overabundance.
The fourth question is "Which nutrients can be supplied exclusively from the water column." As far as I know this remains unanswered as it is extremely difficult to manipulate the nutrient content of saturated soils. dave huebert

anaerobic Literally without air, refers to an area where there is no dissolved oxygen in the water.
Filtration All good filters provide ample filter media surface areas for the colonization of aerobic (oxygen breathing) denitrifying bacteria which break down fish waste.
Aerobic
Requiring oxygen to survive. Many bacteria must have a suitable supply of oxygen to be able to survive and thrive.
Anaerobic - An area of water without dissolved oxygen.
Artemia - brine shrimp.
Biological Filter - A filter which uses bacteria to breakdown waste in the water into substances which are less or not at all toxic.
Dissolved oxygen (DO) is critical for the successful maintenance of oxygen-loving (aerobic) organisms.
As you might suspect, these anaerobic pockets can form in the gravel of tanks with other types of filtration, and, in fact, they are more likely to because the filtration system is not going to be pulling oxygenated water through the gravel.
about 2 weeks until aerobic bacteria called "nitrosomonas" grow to sufficient quantities
in the filter to convert the ammonia to toxic nitrite. (Nitrite destroys the hemoglobin in ...
In the outside of the hole, aerobic bacteria perform the familiar nitrification process (which is the same in saltwater as it is in fresh, though with different bacteria species) of converting ammonia into nitrites, then nitrites into nitrates.
Aerobic bacteria can't survive indefinately in a sealed bottle on a pet store shelf, so I don't trust those products.
While the filter is running properly, these degrade aerobically into compounds like nitrates and phosphates which may be algae stimulants and fish growth inhibitors, but at least are not generally toxic.
The water at the bottom of the filter is fresh and high in dissolved oxygen, so aerobic bacteria cultivate in the bottom half of the sand bed, and remove ammonia and nitrite, using up oxygen in the process.
In nature, when animals expel their wastes and plants decay, anaerobic bacteria in the environment break down waste to harmless nitrogen that is released into the air through the ground and water.
The results of this no-oxygen ( called anoxic [ see Jaubert System ] or anaerobic, meaning low or without oxygen ) environment would be hydrogen sulfate ( that rotten egg smell ), and the bed would eventually 'clump' together and become solid.
Chemoautotrophic bacterial growth will occur in the absense of oygen, so a thick layer (2"-4") is often necessary in separating the high oxygen environment of the reef to the completely anaerobic environment for bacterial growth of the plenum.
If detritus, especially of organic nature remains hidden within the tentacles it will decay and give rise to anaerobic activity and often leads to bacterial infection ...
The fermentation is an anaerobic process and opening the bottle will admit oxygen and stall the fermentation. The yeast will have to use up all the oxygen and then begin fermentation again.
And don't forget that oxygen is essential for the conversion of ammonia into nitrities and then to nitrates by aerobic bacteria. For this reason, bioballs are best when used in a wet-dry deployment.
Collectively the process of turning ammonia to nitrate is called nitrification and is carried out in the presence of oxygen (aerobic conditions).
After a very few hours (less than a day) without a flow of oxygen-laden water, aerobic bacteria start to die.
Removal of your undergravel (or extra thick gravel) will omit the chance of anaerobic bacteria bloom that could cause a complete wipe out of the tank.
Secondly, this compacting can lead to reduced circulation and pockets of anaerobic (not requiring oxygen) bacteria thriving, creating toxic gas bubbles.
For the time being, simply stir the sand that you can reach without dismantling the tank. There shouldn’t be a problem with anaerobic bacteria if you perform that simple task regularly, ...
Denitrification: Breakdown of nitrates by anaerobic bacteria into other forms.
Allows improved oxygenated water flow and increased aerobic bacterial action in the gravel. Can also be used for periodic water changes to maintain a sparkling clean aquarium, free of ammonia and nitrites. Several sizes; all feature 6′ of hose.
If your sand layer is too deep it is likely that you will develop pockets of anaerobic bacteria that can pose problems.
The sand eventually developed sizable anaerobic pockets, which led to water suffused with a sizable amount of hydrogen sulfide.
Scientists solved this problem by allowing these nitrates to turn into nitrogen gas (N2), thanks to the anaerobic bacteria which survive at the bottom of the tank, where the oxygen levels are low.
scales have little or no proection from sharp edges. I have personally had a kuhli slit itself open gills to gizzard on a too sharp rock. Given a sand substrate, kuhlis will burrow, and can be relied upon to keep the sand free of anaerobic pockets.
