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.
