Marineland Emperor Power Filter replacement impeller. Impeller assembly for the 2 Bio-Wheel Emperor 400 Power Filter. Warped, cracked or dirty impellers can reduce the filter's effectiveness and efficiency.
Old, warped impellers can result in decreased water flow, poor circulation, and, in some cases, even an unpleasant grinding noise. Replace the impeller to reinvigorate your filter with strong, silent water pull and maximum circulation.
Clean your impeller assembly regularly to maintain the best possible water flow.
