The Emperor Filter Systems are advanced aquarium technology at its finest. Flow and filtration efficiencies unmatched by other filters in their class; as much as twice the filter cartridge capacity; additional chemical filtration capability; extra effective, spray bar-driven Bio-Wheel wet/dry biological filtration...that's 3-stage Emperor filtration.

The Emperors feature not one pump (as in ordinary power filters), but two separate water pumps. The Flow Pump directs water through the high-capacity Emperor Rite-Size Filter Cartridges and Media Containers. The BIO-Pump then pressurizes and sends streams of pre-filtered, oxygen-rich water through the adjustable spray bars to power each BIO-Wheel.
