So i recently got a new syncra 3.0 silent. Well it turns out its not so silent and now im thinking of returning the pump cus the tank its in my room and i cant really tolerate it. I was wondering if there was way to fix this problem. Its operational noise and im wondering if i can add some type of lube or something. it is not touching anything and it has those robber knobs. im thinking of just pulling the trigger on an M! vectra and re plumb my tank but its to expensive so any advice with a 700GPH return pump with a 1/2" male/female outlet.
