I feel like NOTHING has changed in both columns.
I can't even make any new observations because nothing has [seemed to have] changed.
Column #1:
Column #2:
I think MAYBE the mud level is a bit higher in column #2? If so, it's not by much:
This makes the layer of scum above the water easier to see:

Compared to the photos of this that I had taken previously, I guess the arrangement of gas bubbles may have changed, as some may have gone and some may have formed in a slightly different place.
I still think that the different patches of color on the scum is beautiful.
Browns and oranges and empty spaces inbetween...I think it's really pretty, and it's probably evidence that different bacteria a colonizing this scum layer. I'm sure that methanogens may still be present because the gas bubbles still exist (assuming the gas inside is methane).
