So I would like to know what return pump is quite. I would rather like for someone that has the pump up and running to give there actual experience for all of us to know. Right now I'm using a Rio 3100 for a 60 gal cube. It's a good pump and does its job but there's that vibrating/humming noise, and to top it all off I have laminate flooring so there's no rug absorbing that humming. So the more quiet it gets in my house the louder that pump gets. So let me know whats recommended in your experience since I'll be swapping out pumps..thanks
