If you have it too tightly closed, with too much H2S produced, the bottle could swell.<br /><br />Probably you will get some airborne microorganisms "contaminating" your column. But we never worked under aseptic conditions anyway. <br /><br />What does, in your opinion happen, in the natural environment? What is the fate of these airborne microorganisms?<br /><br />Always more questions than answers...<br /><br />Sokratis<br /><br /> Anonymoushttps://www.blogger.com/profile/16671538935478091986noreply@blogger.comtag:blogger.com,1999:blog-6673091514910383162.post-58823178276162029702015-03-15T13:15:55.902+02:002015-03-15T13:15:55.902+02:00I believe that we added around two spoonful of eac...I believe that we added around two spoonful of each compound.<br />If we keep the top open of the bottle, wouldn´t it get contaminated?diego mateoshttps://www.blogger.com/profile/12665764255968386954noreply@blogger.comtag:blogger.com,1999:blog-6673091514910383162.post-49189480586769360542015-03-15T00:29:48.527+02:002015-03-15T00:29:48.527+02:00I see you have gone all the way!

Do you remember how much you added of each? <br /><br />If you added too much of sulfates, you have made your SRB (sulfate reducing bacteria) very happy and your room mates unhappy. Just remember to keep the bottle top open.<br /><br />Let's see over the days if the ratio of orange to black zones change.<br /><br />Has anyone thought of making a photo every other day under the same light and add all the pictures together in the end? This would make a nice video of the evolution of the column. Something like a "1 sec everyday" video. I think I will make one column myself tomorrow.Anonymoushttps://www.blogger.com/profile/16671538935478091986noreply@blogger.com
