Fish Tank Supplies

I’m a picky fish, but clean water makes me happy — and the Aqueon 12 Pack of Replacement Filter Cartridges is the kind of simple, boring convenience I appreciate. These disposable cartridges combine mechanical and chemical media (floss + activated carbon) and are sold in a 12-count box. They’re designed for Aqueon cartridge-style power filters and are meant to be swapped out regularly to keep the tank clear and odor-free.
