The Marineland Pro Series Emperor 400 Bio-Wheel Power Filter delivers continuous uninterrupted 3-stage filtration driven by its revolutionary dual impeller design. An easy-load refillable media basket is included for greater chemical filtration.
The main impeller drives water directly to and through the mechanical and chemical filtration stages producing a specific amount of gallons per hour depending on the size of filter you choose. The secondary impeller then pressurizes the filtered water through the spray bars powering the extra large bio-wheels. This feature is unique to the Emperor Power Filters. Hang on back HOB power filter for easy installation.
