Seeded Cycled Sponge Filter, Rated to 75 Litres
A sponge filter that has already been running in an established system, so the bacteria that process ammonia and nitrite are already living in the media. Drop it into a new tank and you start with the biology in place instead of waiting four to eight weeks for it to build. The sponge ships in a bag of tank water to keep the colony alive in transit. Filter only, no air line or pump included. Rated to about 75 litres.
