bubble trap

Trying to just get everything figured out before I start putting together my sump. I have a 29 gallon and am planning on getting a kit for it similar to the Fiji Cube kit. It will have 4 chambers, one for the filter socks, one for the skimmer, one for biomedia/Chaeto, and one for a return pump...

I've seen 2 different designs of bubble traps. Which of the 2 do you think is better in terms of eliminating microbubbles? I was thinking that maybe #1 would be more effective, since water runs through a certain length without contact with the air and then goes directly to the return pump...
