well maybe I was just seeing things... I dropped by the house on my way back from a delivery to find the tank just as full of bubbles as yesterday. I guess I should wipe the sleep out of my eyes before checking the tank.

Do you think a piece of screen (like on a window) would trap microbubbles? I'll be heading to the HD after work for the female thread and 90° while I'm there I might pick up a piece of plastic screen just to see if I can capture a few bubbles with it. If so I'll rig up a pvc frame
