ok i finally finished the water movement in my 3g. but now i have a bigger problem. since its in my room i need it as quiet as possible.

i even took the rio 90 out of the return chamber to decrease the noise but its not helping. theres a somewhat of a loud rumbling. i can hear it 15 feet away...

does anyone know how to reduce the noise lvl?
