do the rio nano, rated for the 20 gallons tank, make a lot of noise? Because mine is making a ton of vibrating noises?

thanks, i actually read on like some other forum that if you glue the impeller to the magnet, it stops being so noisy. i did that and its not as loud any more

but what do you know about the micro bubbles it puts out?
