If you have a lot of lily pads, you might be wise to spray only a portion of them at a time. Too many decaying all at once could deplete oxygen.
I'm doing them in strips but I have so many my current one only does 15-20 feet on a good day and that's just not enough on a lake that's over 1,000 feet wide and the lily pads are in some places up to 40-60 feet from the shore.
