Impellers - from Aqua One Parts
Aqua One Impellers work extremely hard in your Filter Pump, spinning many thousands of times an hour. It's essential to check your filter pump impeller on a weekly basis, to ensure that it hasn't become blocked with aquarium debris. Most impellers are magnetic and are fairly easy to change. It's best to change your filter pump impeller every 12 months to help prolong the life of your filter pump. It's also smart to keep a spare. See all Aqua One Filtration.
