The Finest Filters replacement activated carbon impregnated foam filter pads are compatible with the Fluval FX4, FX5 and FX6 range of external filters.

Please select the number of carbon impregnated filter foams you require from the drop down menu when ordering.

These carbon impregnated pads capture micro particles as the water passes through. The added carbon removes odour, discoloration, as well as heavy metals and organic contaminants, giving crystal clear water in your aquarium.

These carbon impregnated filter pads are suitable for both freshwater and marine aquariums.

Please Note: These are NOT original spare parts - these are compatible filters manufactured by Finest Filters.

We also sell a range of other filter foams for the Fluval FX4, FX5 and FX6 filters, including pre filter foams, bio-foams and Water Polishing Pads! Why not have a look at our other items in our eBay shop?
