I think you are right with the seal. I had put the lid in a star san bucket while i was testing gravity, and when i put it back on wet. it began to bubble a lot out of the lock. But as it dried up, the bubbling slowed again. I hoping its because of this and not just shaking up the yeast from moving it onto the kitchen table.
another note...checked the gravity on it. It has def been at work... the reading was at 1.018. I was going to let it sit a couple weeks in the primary anyway. there was a nice layer of krausen at the top, so something must be working since that wasd happening and the gravity had dropped.
it smelled fine, not like anything was wrong. unfortunately, I couldnt see the top of the liquid to see if anything was infected.
i think i will be using my carboy as my primary from now on. I like to see the fermentation at work
