Aqua One 39i Impeller Set for the CF1000 and CF12000 canister filters

A brand new Aqua One 39i Impeller to fit the Aqua One CF 1000 and Aqua One CF 1200 external canister filters. It’s a simple thirty second job to change a 39i impeller and well worth doing as it’s the only moving part in the whole filter and subject to a fair bit of wear and tear
