Genuine Fluval activated carbon bags for compatible EVO, SPEC and original FLEX desktop aquarium filtration systems. The carbon adsorbs dissolved impurities and helps reduce odors and discoloration.

• Contains three replacement carbon bags.
• Provides chemical filtration alongside your existing mechanical and biological media.
• Check the aquarium manual and existing cartridge dimensions before ordering; not a universal fit or a FLEX 2.0 Poly-Carb cartridge.

Rinse before use and replace as directed by Fluval. Remove carbon when a medication’s instructions require it.
