Alright, i ahve my NEW cascade 1000 on my 75g running, no sand or anyhting just water and it is making noise. It is just a constant hum but it is not really load just none stop. Is there any way i can stop this? Because i would like too. The stand has no doors were it is in and my mom said she thinks i would not be able to hear with the doors on. Is there any way i can quite it?
