An update...had a local professional come out. His take was that it's actually duckweed *and* watermeal and he recommended simply treating it all with Sonar. So that's what we've done, now just waiting on it to work. He recommended turning off my aerator for the first week, but said we could turn it back on after that. Not sure I need it, though. Things seemed to be doing just fine before the darned plants took over.
