The Cascade 1000 Impeller replaces the impeller for the Cascade 1000 canister filter. Replacing an old impeller is essential to keep your filter running powerfully and efficiently.
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.
Note: For the Cascade 1000 canister filter only. Cascade 1200 and 1500 models each require different impellers.
