I tried fixing the motor by putting some Vaseline in the impeller but it still makes the grinding sound.
Aquaclears overflow when the media is too tall or too dense in the basket. What did you put in there? Did you try turning the flow-rate on the filter down?
Once in a while you get a really loud aquaclear, or a little piece of the impeller's magnetic base snaps off and grinds against the impeller causing more damage and lots of noise.
Don't go with another brand, stick with Aquaclear, just hope you get a quieter one.
