Mead | Vigorous Bubbling?

[froslie]

I have started two separate wild-ferments for mead; both started with a ginger bug. They seem to be very happy after a few days, so I'm trying to determine when they are 'vigorously bubbling'.

They have a thin foamy layer at the top, which is more prominent when I stir. Should I be watching for active bubbles popping, or this thin layer enough to move the to their respective carboys??

{IMG} the smaller batch has juniper berries - those are the dark spots in the image.

Thank you for any suggestions...
