Ceramic Bio Media for the Submersible Pond Filter.
Why use ceramic filtration rings? Biological Filtration!!
The most important part of an aquarium’s filtration system is the biological filtration. In many aquariums, this is made up chiefly by ceramic rings, and partly by the filter sponge. The ceramic rings and filter sponge provide a very large surface area on which friendly bacteria can live. This bacteria is required for the aquarium cycle, which converts harmful ammonia and nitrite in to the less harmful nitrate.
To maximise biological filtration, a generous stock of ceramic rings (or similar) should be kept in the aquarium at all times. When the ceramic rings become dirty it is better to clean them (using old water from the aquarium) rather than replace them, otherwise the good bacteria will have to grow all over again which can take many weeks. For the same reason, the filter sponge should only be replaced once every 3 months (but cleaned every month using old water from the aquarium).
