Introduction |
If your hang-on-back (HOB) aquarium style filter is making a buzzing noise, has reduced flow, or has stopped working completely the impeller inside the motor has mostlymost likely been chipped or cracked from long-term wear. | | | Use this guide to remove the damaged impeller and replace it with a new one. This involves removing the filter motor to access the damaged impeller and cleaning the impeller shaft before installing the new impeller. | | | This guide demonstrates this process on an AZOO Mignon 60 (AZ13097), but the procedure is the same for all HOB filters with a detachable motor. This includes brands like Aqua Clear, Fluval, Marineland, and Cascade. If you are using this guide for a different brand of filter a larger impeller replacement may need to be purchased. | | | Working with water and electronics is a safety risk. When connecting and detaching your filter from a power source ensure that your hands and the external area of the motor are completely dry. | | | Before beginning this guide, disconnect your filter from its power source and remove it from your aquarium. |
