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 as it spins at thousands of revolutions every minute of every day. Change once per year for constant quiet filter performance. Keeping a spare Aqua One 39i impeller for your filter is one of the smartest things you can do to protect the health of your live stock.
