Product Information

Swell Ceramic Bio Media is a very porous biological filter media with an extremely large surface area which encourages bacteria to congregate.

It is among the best ceramic media for aquariums and is low maintenance. It can also be used in ponds.

Swell Ceramic Bio Media has a very porous surface which allows a much higher flow rate through the filter unlike some media which will slow it down as it becomes clogged very easily. The porous surface means it is ideal for large filter bacteria to colonise. Ceramic media is considered better than plastic filter media as it holds up to 10 times more bacteria.

The bio media is ideally placed in external filters as a replacement for foam media, it can also be used as a replacement media for Biorb Aquariums.

The bio media is great for adding to existing filters and new filters to boost capacity allowing the filter to work at its maximum. It can be used in any external aquarium filters or pond filters.

The pieces are around 2-5cm but it can easily be crushed up to fit even the smallest filters.

Weight: 750g


Place in filter system, rinse thoroughly before use. Take care when handling as pieces can be sharp.
