Koi Filter Media

Our range of Pumice Koi Filter Media is now being used extensively as an alternative to traditional koi pond filter media in trickling filters and trickle towers. Our Koi Filter Media is inert and rapidly colonises with beneficial bacteria which help cleanse the pollutants. It is highly porous making it the ideal media for biological filters of all kinds.



Efficient biological filtration depends on the media of choice having an adequate specific surface area (SSA), adequate voiding and water retention time. Our Pumice Koi Filter media has a massive surface area and is therefore ideal in this application. Our Koi Filter Media can be used as a direct replacement to other ceramic based filter media.
