Aqueon Mini Bow Filter Cartridge 3 Pack

These replacement filter cartridges are perfect for 2.5 and 5.0-gallon mini aquariums. Comes in a convenient 3-pack, small in size but big on performance!

Using these Aqueon filter cartridges is easy. Just remove the old cartridge from your 2.5 or 5.0-gallon mini aquarium and replace it with a new one. Make sure it fits snugly in the filter compartment. As for maintenance, it's a good idea to replace the cartridge every 2 - 4 weeks, depending on your aquarium's water quality. Keep an eye on the water clarity. If it starts to get cloudy, it might be time for a new cartridge. When handling the cartridges, try to keep them dry until you're ready to use them. Also, store the extra cartridges in a cool, dry place to maintain their effectiveness.
