Swell Ceramic Media is a very porous biological filter media with an extremely large surface area which encourages bacteria to congregate.
Swell Ceramic Media is among the best ceramic media for ponds and is very low maintenance. It can also be used in aquariums.
It 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. Theporous 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 great for adding to existing filters and new filters to boost capacity allowing the filter to work at its maximum.
The pieces are around 2-5cm but are easily crushed up to fit even the smallest filters.
Application: Place in filter system, rinse thoroughly before use. Take care when handling as pieces can be sharp.
