Review on 🐠 Eheim AEH7633100 Impeller 2215: Enhancing Aquarium Water Pump Performance by Tamika Lawrence

Saved me! Our 15 year old Eheim pump would occasionally click and then vibrate loudly as if trying to get out from under our 100 liter tanks. I've resigned myself to buying another $200 unit or at least a new power head (above) which is probably 3/4 the price. This twenty dollar miracle has done it. It is a propeller mounted on the end of a rod, the other end of which is surrounded by a "big" and powerful magnet. Most of the device shown in the picture is just a protective plastic frame that should be thrown away. Replacing parts and bringing new life to your filter takes less than 5 minutes.
