I do have a sump and return set up with a seaclone 100 skimmer. I have been watching these items as well as everything else but haven't seen any evidence of them producing any bubbles or micro bubbles. When you look at the water with just the moon lights on there is a few bubbles in the water. The only time/place that we see these bubbles is on our live rock and on the gravel base. We get rid of as much of these water bubbles as we can during the water change stage but they start showing up within a week.
We have been running this tank set up for 9 months and this problems starting showing up a couple of months ago
