Eric, could this �stuff� be �dead plankton cytoplasm ooze� that you described?
I observed and photographed this at a central Kansas pond the past weekend.
Pond is ~1/2 acre, surrounded by cottonwood and willow trees with decaying leaves around shore, supposedly 12 ft deep at dam, and obviously shallow upper end.
� hp Gast, 2 diffuser aeration system � runs 24/7.
