Eric,
My present thoughts are that it is chara because it does not seem to be rooted. I unfortunatelydid not crush any of it to see what it smelled like.
When I first looked at it, I assumed it was slender pondweed. I'm fairly certain it is not naiad nor sago, but I've ruled out elodea either. It is like long slender green grass or hair. It is not slimy.
I can get more photos if that would help.
Presently the only noticeable wildlife in the pond are large unidentified turtles. They are pretty much all black, and the size and shape of WW-II German army helmets. There are also some pretty good size bull frogs and other smaller frogs.
My immediate concern is getting it cleaned out. Not knowing whether it is a weed or an algae has some bearing on this. If we take it out mechanically I'm afraid I'm going to leaving rhizomes, seeds, maybe roots, etc. If I use a chemical, dies, and all sinks to the bottom I'm afraid I'll create a stinky swamp.
Thanks,
Ken
