Man made [tag-tec]aquarium filtration[/tag-tec] is a term I use when describing filtration devices which are not naturally occurring. This is equipment which is used to grow or culture the bacteria required to provide an efficient [tag-tec]aquarium filter[/tag-tec].
Good examples of man made filtration are but not limited to :
- External Canister Filters
- Internal Filters
- Fluidised Filters.
The majority of man made filters effectively follow the same principal and the majority of them utilise both mechanical filtration and biological filtration.
