About This

• Our carbon filter pads are intended as an alternative to the poly/carbon cartridge, and offer excellent chemical carbon filtration in the aquarium.
• These filter pads are cut to fit the Fluval U3 range of internal filters.
• Please note: There is no poly side to these filters. They are just Activated Carbon impregnated foam.
• This is not a Fluval Product. This is a Finest-Filters alternative which serves the same purpose as the origional brand.
