The Marineland Emperor Power Filter with Bio-Wheel is available in two models: the Emperor 280 Aquarium Filter and the Emperor 400 Aquarium Filter. Both "Hang-On Back" (HOB) aquarium filter systems feature 2 separate water pumps. The Bio-pump pressurizes and sends streams of pre-filtered, oxygen rich water to each Bio-Wheel, while the Rite Size E 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 aquarium power filter for your aquarium. Requires 9.5" of space along the back of your aquarium. Both Emperor Bio Wheel filters come complete with Rite Size E filter cartridges, refillable media container, and Bio-Wheel assembly.
