12 x Fluval U2 Compatible Plain Foam and 12 x Compatible Polycarbon Filter Cartridges

You are buying a set of 12 compatible plain filter foams and 12 x compatible polycarbon filter cartridges to fit the Fluval U2 internal filter.

The plain foams are responsible for mechanically filtering the water by removing large particulate waste.

The polycarbon filter cartridges have a polyester side for mechanical filtration of finer particles, and a carbon impregnated side for chemical filtration of the aquarium water.

Regular replacement of the filter foams and cartridges in your filter will ensure that your filter is running at its best.
