12.11.14: Why is nothing else happening?

I feel like the most exciting days of this Winogradsky column were near the beginning.
For the past week, my column has literally looked the same.

Column #1:

The mud didn't rise any higher.
The mud is still slightly orange-tinged below the red rubber band (which was speculated to be bacteria).
There is still a water layer/gab between two mud layers, more near the top of the column
There are still black-tinged spots near the bottom of the column by the gas bubbles.






Column #2:

The mud levels in column #2 never rose quite as high as they did in column #1. 
This may be due to the presence of oxygen, making it an aerobic process. I see a noticeable difference in number of gas bubbles as well, which are lesser in column #2
As a general note, there is a noticeable scum layer in column #2, but not in column #1.

Why did my water in column #2 get so turbid?



That's funny: there is still a lot of twigs and earthy plant matter in column #2. Here it is sticking out:


Ugh! Look at that scum layer resting on top of the water:
