Hey guys. I just set up my sump today with a Gen-X PCX-40 as my return pump and I must say that this pump is LOUD! Its so loud that I can hear it throughout the entire downsairs of my house. Any thoughts as to how to reduce the noise without replacing the pump? Are your pumps loud at all for your returns? This is really bothering me because my tank is in my living room and i really did not expect it to be this loud at all. Thoughts? Thanks.:feedback:
