Yeah the unit is a bit noisy and I find myself having to turn up the TV volume a bit to hear it over the remora pro. The noise is not much of an issue to me though, especially since this is a truly remarkable skimmer. I have the mag 3 pump on it and find myself emptying a full cup of murky skimmate a day. I can not believe the skimmate this thing produces, it is remarkable. Plus it keeps my tank water sparkly clean.
