mike, i realize every pond is different, but last year i had alot of APweed too. i've been really impressed that routine aeration this summer has kept that, FA, and elodea in pretty good check. last year prob. 60% of pond was covered with weeds, this year about only 20% of pond covered with weeds with no mechanical or chemical harvesting. i believe the major factor in my pond is that the aeration has reduced the clarity, promoted plankton bloom, and thus kept light from penetrating deep.
