Impeller Nanoskim 90 111I Kongs

A brand new Aqua One 111i Impeller to fit the Aqua One NanoSkim 90. It’s a simple two minute job to change this impeller and well worth doing as it’s the only moving part in the whole Skimmer 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 pump performance.Inspect the impeller and rinse it clean once per month as it will get coated with bacteria and silt. Change the diffuser at the same time to maintain good air throughput.
