BioCube Filter Cartridge
BioCube Aquariums include a sophisticated filtration system with a two-stage disposable cartridge that provides both mechanical and chemical filtration for clear, debris-free water. The poly-woven pre-filter traps free-floating materials and waste while the activated carbon removes odors and discoloration. Replace cartridges every 6 weeks for best results.
