Pumice stone Filter Media is now being used extensively as an alternative to traditional koi pond filter media in trickle filters and trickle towers. It 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. Pumice Stone Filter media has a massive surface area and is therefore ideal in this application. It can be used as a direct replacement to other ceramic based filter media.
