The crazy thing is that your photos look a lot like what I'm dealing with. Maybe I missed the answer, but the answers you got seem to be the same as I've gotten so far for what appears to be the same problem.
FnC -- did you ever find an answer? Did you find out what it was -- specifically, was it algae or a rooted plant?
I really would like to get any clues that someone might have.
Do to multiple budget cuts at nearly all levels, including elimination of our multi-state University Extension Aquaculture services, I'm not sure where to turn if my PB friends/experts don't have any good answers.
My experience with our largest local interstate aquaculture consulting company has been far less than professional.
Oh well.
Thanks all,
Ken
