Marineland Replacement Impeller for Explorer, Eclipse System 3 gallon (PFES03), Hex 5, and Corner 5 integrated aquarium systems. Replacing an old impeller is essential to keep your filter running powerfully and efficiently.
This specific impeller is green.
Old 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.
