About This Item


  • Keeps water crystal clear. The dense woven floss acts as a pre-filter 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. It is designed to efficiently remove harmful microorganisms and other impurities, and improve overall water equality for delicate aquatic ecosystems.
  • The Coralife filter cartridge can assist in eliminating unpleasant odors.
  • Designed to help remove discoloration, so your fish can see more clearly.
  • A great way to keep freshwater aquariums in good condition for your finned friends.
  • Comes with two filter cartridges and fits all sizes of the BioCube all-inclusive aquarium systems.
