200g Ceramic Bio Rings

Pond or Aquarium Filter Media

 

You would be buying 200 grams (minimum) of brand new Ceramic Rings

in a resealable polythene bag.

 

These Ceramic Rings are an excellent biological filter media for both Freshwater and Saltwater.

 

The rings are made of highly porous, non-toxic, inert materials which promote the growth of nitrifying bacteria.

 

The hollow design aids water flow and also maximises the surface area on which the nitrifying bacteria colonies grow.

 

These strong ceramic rings act as an efficient long term, reusable filter media.

 

Each ceramic ring is approximately 13mm high with an approximate 13mm diameter.

 

There are approximately 41-43 ceramic rings in 100 grams.

 

Rinse before use.
