GPH Too Strong For Tank [Sump Setup]

  • We are currently upgrading MFK. thanks! -neo
The gurgle came back again after I did the unplug of the 9.5 and replug in. Now it's there whenever I plug it in.

Anyone have any ideas? It WAS silent for a bit when I put the airline down the tubes. Are they maybe too far down in the tubes? Not far enough down?... I'm totally at a lose at this point.
