Well something certainly went wrong...partial kill in both puddles but not complete in either one. I set traps in both overnight and caught fish in both.
So back to Menards I go, and I'm going to double apply. At this rate I'll have more $$ in Lime than I do in fuel to run the pump to drain the pond in the first place.
I'm guessing my volume calc was off, although I can't figure out how. I'm also trying to kill GSF fry, which are notoriously hardy.
