Aqua One Impeller Set - 2250UV/2450UV Advance 405i

A brand new Aqua One 405i Impeller to fit the Aqua One Advance 2250 and Advance 2245 external canister filters with UV. It’s a simple thirty second job to change this 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 impeller for yor filter is one of the smartest things you can do to protect the health of your live stock.
