Do you happen to have sand in the tank? If so, make sure you clean the sand out, and install a foam accessory over the bottom strainer. If not, but you have a bubbler in the tank, shut the bubbler off for a few hours and see if that helps remove the noise. Make sure you check for anything caught in the motor area as well. If you are unable to resolve the issue, there is a 5 year warranty on this filter, with receipt. We also sell the impeller separately. For warranty, call 1-800-322-1266.
