My Return Pump Is Making This Extrenely Annoying Noise. How Can I Fix It? I Have A Mag 5

take it apart, their might be something in the impeller.
Water level high high enough in sump?
If its vibrating and the noise is annoying, try a mouse pad under the pump or something aquarium safe to reduce the vibration. It could also be an issue with the pump. Have you cleaned it at all?
You just open up the part where the impeller is. No screwdrivers or anything. Then you can take out the impeller, clean it, clean the spot where it goes back in and put it all back together. Should be good as new.
