Aqua One Impeller Set – MSD-1 Protein Skimmer 45i

A brand new Aqua One 45i Impeller to fit the Aqua One MSD-1 protein skimmer. It’s a simple five 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 skimmer performance. Keeping a spare impeller for your skimmer is one of the smartest things you can do to protect the health of your live stock.
