Betta Filter Replacement Cartridge, 2-Pack
Aqueon Betta Filters are air-operated filters that improve water quality by filtering water in small betta habitats, such as bowls and aquariums up to 3 gallons. Replaceable carbon and sponge cartridge keeps water cleaner and clearer. Each filter comes with a decoration (natural plant or volcano) to hide the filter, along with the accessories for its operation (air line tube, air line tube suction cups, air adjustment valve and check valve). An air pump (not included) is required to operate the betta filters, the Aqueon QuietFlow 10 air pump (sold separately) is suggested.
