Why are white ceramic rings used in aquarium biological filters? Whats the use and benefit of it?

Answer 1

Bioligical filters work because they're colonies of bacteria. The ceramic rings are porous with extremely high surface area, allowing these colonies to grow in abundance. The rings are bulky, packing loosely, allowing for water to flow easily over all the surface of the rings, which allows more of the chemicals to be treated by the filter. The rings are also inert so they won't kill your precious swimmers.

Answer 2

The ceramic cloth that those rings are produced from is actual very porous, whether they supply the effect of being stable, there are zillions of tiny holes in it, and that makes it an suited residing house for the cycle micro organism which you particularly choose in the clear out. Carbon serves a different purpose the place it bodily absorbs chemical components from the water. then you definitely regulate the carbon after some weeks, and throw out those pollutants. No reason you could not use the two sort of media on your clear out, however the organic and organic filtering that the ceramic rings do superb is the main serious. The chemical filtering action of the carbon is way less significant, until eventually you attempt to get rid of drugs or tannin from driftwood, so because it extremely is non-obligatory. Ian

Answer 3

There ceramic is a particular type which is very porous and has lots of surface area for bacteria to breed. These are the good bacteria which change your ammonia ( from fish waste and decay of plants etc) into nitrites, and then different bacteria which share the media, will change if from nitrites to nitrates.
Ammonia and nitrites are highly poisonous to fish, nitrate is also poisonous but the levels have to be very high to actually affect the fish.
This is the biological filter.
The mechanical filter merely catches particles of debris in its structure.
