just got my tank filled and up and running . 2 brand new A.C 50s and both sound like they are vibrating . any clues ??
1. Is basket hitting lid
2. Motor dirty
3. Propeller damaged or not seated
Lube magnet on propeller
basket not hitting lid
motor is brand new and confirmed free of debris
propeller spins feely until it hits bump / keyway on shaft
lube with what that will not contaminate water ?
