Vibration in Nano-cube

[dendro982]

I have Nano-Cube 6 g, everything was removed from the back chambers, now the LR rubble is in the 1st chamber, heater in the 2nd chamber, Mini-Jet 606 in the 3rd chamber, hanging on the 90 degree elbow with original flexible tubing.
It replaced Maxi-Jet 600 (same gph), that was too big and vibrated too much.

Now much better, still, if place the ear on the glass wall, vibration continue to be, should be maddening for a fish.

Your experience and solutions?
Is there even more quiet small pump? Or different way of attaching?

I installed the bracket on the pump along with the suction cups. The suction cups seem to cut down on the vibrations, did you try that?

Found the reason of the recent vibration rise - the pump was not at the right angle to the outflow elbow - was kicking both walls, corrected.
But humm was left.

About use of the suction cups: did that - was very difficult to remove the small pump from the bottom of the narrow chamber, these small suction cups are surprisingly strong, then followed another variant - just hanged pump on the elbow, no pump's side touches walls at all, only vibration, going through the elbow.
