This system breaks down any toxic compounds, usually Nitrogenous toxins. The Nitrogen Cycle
Biological filtration is always the primary filtration. Biological filtration converts highly toxic waste, which are produced by the animals in the aquarium system, into less toxic nutrients through the activity of nitrifying bacteria.
These filters make use of bacteria to break down wastes in the water into substances which are less toxic to the inhabitants, in a process known as the nitrogen cycle. Examples are under gravel filters, sponge filters, and trickle filters.
The process of passing water over colonies of beneficial bacteria which processes the ammonia secreted by fish and other living things to nitrate.
A loose term that describes the process of removing harmful compounds with bacteria. Actually, it is not filtration at all. Instead, it is the mixing of aquarium water with beneficial bacteria that transform wastes in the water into substances which are less toxic to the inhabitants, in a process known as the nitrogen cycle. This process is accomplished by trickle filters (ammonia towers), UGF (undergravel filters) sponge filters, and various other specialty filters.
The use of biomedia and beneficial bacteria to filter water.
One component of a total filtration system. A method of treating water that relies on the presence of beneficial bacteria to convert toxic substances into relatively harmless ones. This process is accomplished by trickle filters, undergravel filters, and in sections of compound filters.
A method of natural filtration that uses bacteria to break down waste substances by means of the nitrogen cycle. These include undergravel filters, trickle filters, and sponge filters.
