The Emperor Power Filter is available in two models: the Emperor 280 Filter and the Emperor 400 filter. Both models feature 2 separate water pumps. The Bio-pump pressurizes and sends streams of pre-filtered, oxygen rich water to each Bio-Wheel while the filter cartridges trap debris and remove dissolved contaminants. Refillable media containers hold an additional 4 oz. of chemical filtration media for maximum pollution removal. The Marineland Emperor 400 or 280 is the ideal power filter for your aquarium. Requires 9.5" of space along the back of your aquarium. Comes complete with filter cartridges, refillable media container, and Bio-Wheel assembly.

Emperor 280 for aquariums up to 50 gallons.

Emperor 400 for aquariums up to 90 gallons.
