Aqueon Replacement Filter Cartridges 6 pack Medium 4.9" x 2" x 5.7"

Keep your aquarium filter running at peak performance with Aqueon Replacement Filter Cartridges. These medium-size cartridges are uniquely designed to ensure even distribution of activated carbon throughout the cartridge for more thorough filtration and a longer cartridge life. High-quality activated carbon absorbs impurities, odors, and discoloration, keeping your aquarium water crystal clear between water changes. A bottom key slot ensures an accurate, secure fit inside compatible filters every time.

For best results, rinse the cartridge under water before installing to remove carbon dust, and replace every 4 to 6 weeks. When replacing, leave the Bioholster in place — it contains beneficial biological bacteria essential to a healthy aquarium ecosystem. Comes in a convenient 6-pack so you're always stocked up.
