Aquarium & Fish Tank Pumps Spare Parts

Keeping your existing pump running rather than replacing it outright is usually the cheaper and more sustainable option, and it's often a quick fix once you have the correct impeller or shaft in hand. Before ordering, double check the exact model and wattage printed on your pump housing, as impellers are rarely interchangeable between different ranges even when pumps look similar in size. It's also a good opportunity to review whether your pump's flow rate still suits your tank, especially if you've added more fish or plants since it was first installed; our Fish Tank Volume Calculator can help you work out what output you actually need. A well-matched, properly maintained pump keeps water moving efficiently without unnecessary running costs.
