Micro bubbles

[outtafocus]

Micro bubbles seem to continue to flow through my bubbletrap and get pumped back up to my display tank.
I believe the speed the water is forced to move through my sump drags the bubbles through my trap.

I know this isnt a huge issue, but I would like to eliminate this distraction from my display.

I have heard that a 100 micron filter bag or sock should stop most of the bubbles. Has anyone one had any experience with using one for this purpose?

I have only been able to find 100 micron filter pads, but I have also only looked in two shops, any idea on where to find these socks?

Does any one know of another solution?
