My 55 gal tank has a emperoer 400 that is making a real loud noise. I have taken everything apart and the motor makes no noise when the impeller is out. There nothing in the way. I have the bio wheels in the tank floating. is that okay. Do I need a new impeller or a whole new unit? It is 10:17 pm and every thing is closed. There is a air bubble maker in there. Are the fish okay?
