    Thanks everybody for your input.

    I think I'm gonna stick to my guns on cyanobacteria (Blue-Green Algae). It's slimey and jelly-like but is a translucent green color indicating chlorophyll (kind of like mucus). This seems to contradict the "dog vomit" discription of slime mold. [img]http://www.**********.com/iB_html/non-cgi/emoticons/biggrin.gif[/img]

    I suspect that it's growth has something to do with nitrogen and phosphate levels.
    DOH!

    I don't think that i said that slime mold was an algae. I was trying to make the point that it was probably an algae and NOT a slime mold.[/QUOTE]
    Dodec,

    You didn't say that one was the other. I was agreeing with you that it is algae [img]http://www.**********.com/iB_html/non-cgi/emoticons/smile.gif[/img]

    like Dodec I believe that the green goo growing in most of your pots is a form of algae.[/QUOTE]

    As for the cyanobacteria, it has been forever and a day since I actually read anything about them so I am very likely mistaken. I was just thinking of those mounds in tidal regions that they speculate are probably similar to the first oxygen producing lifeforms

    Hi guys,
    After rereading the above I think I'm now on the same 'wavelength' as you [img]http://www.**********.com/iB_html/non-cgi/emoticons/wink.gif[/img] [img]http://www.**********.com/iB_html/non-cgi/emoticons/biggrin.gif[/img] . I agree that the green slime is probably a type of algae. However he made reference to slime mold and slime fungus. My first thought was of the picture someone posted a while back with slime mold growing on their VFT (I think it was a VFT). A clear/white growth that 'rapidly' move up the leave stalk.

    Pyro, I'd forgotten about the biofilm aspect of slime bacteria. I am more familiar with it in the extended aeration process of wastewater treatment where it forms in clumps (flocks) as apposed to other methods such as trickle filters and RBC (rotating biological contact) units. DUH! Looks like I better hit the books hard for my class 'B' certification test this Fall.

    A clear/white mold like growth is probably just a really nasty mold like Botrytis.

    Slime molds are pretty distinct:



    or



    And as for your wastewater biofilms, I think the only thing I can say to that is: Eewwww!

    Mine looks absolutely nothing like the two pictures above...
    Times like these I wish I had my own digital camera.
    DOH!

    Well since I haven't been around trickle filters or RBC's I can't speek for them but the smell from an extended aeration basin smells like freshly turned loamy earth. Drying beds are another story [img]http://www.**********.com/iB_html/non-cgi/emoticons/wink.gif[/img] [img]http://www.**********.com/iB_html/non-cgi/emoticons/biggrin.gif[/img] .

    Cchang,

    I still vote algae for the stuff most of os are growing in our pots.

    BCK,

    I was more thinking of the nasty stuff in wastewater (i.e. what is brown and sounds like a bell? LOL)

    If that is the same as my green slime it isn't true blue-green algea, I scoped it out and it's a photosynthetic bacteria colony. Basically blue green algea without the cell wall (yes I know it's genetically different, I'm trying to keep things symple).
    There is no item greater in value than life, for without life value would cease to exist.
