I have one like it, and even if i concentrate i can't hear it, so i have to open the lid to my tank to make sure it's actually running :/CODzilla;3656971; said:I use a Tetra EX 2400 and it's like having a running motor bike parked in the living room and that's with the new motorhead they sent me!!
It does a good job on the filtration side I just wish it wasn't so noisey! Tetra have great customer service, it's just a shame their products aren't as great.
