The Eheim Aquaball 60l may vibrate due to a few reasons. One possible reason is that the impeller inside the filter may be unbalanced or dirty, causing it to vibrate as it spins. Another reason could be that the filter is not sitting on a level surface, causing it to vibrate as it operates. Additionally, if the filter is clogged or the water flow is restricted, it may cause the motor to work harder and vibrate as a result. Regular maintenance and cleaning of the filter can help reduce vibration and ensure smooth operation. **
