Aqua One Impeller Set – Aqus 500/700 Canisters

A brand new Aqua One 37i Impeller to fit the Aqua One CF500 and Aqua One CF700 external canister filters.

It’s a simple thirty second job to change a 37i 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.
