    Hello, winobloggers. We've got news! There's an important change in the bottle: seaweeds have appeared! 
    As you can observe in the photographs, seaweeds have appeared in the surface. It's due to the energy from the sun, oxygen and watter.
    Then, the other change is that orange areas are becoming bigger, so that black spots are disappearing. It's due to sulphur has been almost finished.

    There isn't many changes in the dark side of the bottle.

  2. I think you have the most rapidly changing column. Lucky you and thank you for sharing.

    What are the "sea weeds"? I mean what type of organisms are they? What do you think changed so they appeared now?

  3. It seems we have some chlorophytes (from what I can see from the photo) growing growing at the sediment/water interface. This means that the water (and the top few mm of the sediment) is oxic; did the water turn out anoxic? Did it ever smell H2S?
