Aqueon Replacement Betta Filter 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. The replaceable carbon and sponge cartridge keeps water cleaner and clearer. Each filter comes with a decoration (natural plant or volcano) to conceal the filter, along with accessories for operation (airline tubing, airline tubing suction cups, air adjustment valve and check valve). An air pump (not included) is required to operate the betta filters, Aqueon QuietFlow Air Pump 10 (sold separately) is suggested.
The patented dual-sided replacement dense-floss cartridges contain over 25% more activated carbon than the leading brands, and have been designed to ensure even distribution of carbon throughout. The dense floss removes particles and debris, and the activated carbon removes toxins, odors, and discoloration.
