Fluidized Bed Biological Filters

Fluidized Bed Biofilter with Re-Air Tower

Fluidized Bed Biological Filters have a long-established reputation as a small footprint/high surface area bio-filter. When space is limited, fluidized bed biofilters should be considered in your aquarium filtration system.

Emperor Aquatics, Inc.'s Fluidized Bed Filters use a 1mm silica sand or garnet that offers a tremendous amount of surface area for colonizing "aerobic" bacteria. The Fluidized Bed Biofilter is more efficient at TAN (total ammonia nitrogen) removal than packed column style biofilters.

  • Up-flow design allows solid particles to pass through the bed rather than become trapped and potentially damage the system
  • Exclusive Emperor Aquatics, Inc.'s "U" design, in combination with the inlet's swing check valve, prevents the sand media bed from packing down inside the filter during start-up
  • Inlet Gate Valve allows precise media bed level adjustments
  • Durable Heavy-Wall Plastic Construction
  • Optional Re-Air Tower
  • Optimal TAN removal rates
  • Easy to install and operate
