Hey, I just bought a 175 gallon tank wit the FX5. I heard that it's suppose to be very quiet but mine makes a lot of noise. I exchanged it to be sure and I still have the same problem with the new one. Ppl told me to shake it, but it doesn't do anything. The bubble noises stopped but it still makes noise. Is it normal? Anything I can do?!
Thanx
Thanx
