Coralife Biocube Filter Cartridge – 2 Pack

BioCube® premium filter cartridges feature dual-action filtration. The dense woven floss acts as a prefilter to clear detritus and debris while the activated carbon removes odor, organics and discoloration. The rigid frame ensures that water passes through the cartridge and not around it for optimal water filtration. When aquarium systems require more than just the basics — Coralife steps in. From the all-inclusive BioCube aquariums to a complete range of lighting and equipment, the Coralife brand is designed to meet the needs of the more advanced aquatic hobbyist.
