Pond Boss Forums MANAGING AN EXISTING POND Evaluating and adjusting fish populations Draining a Hole on Creek?

After pumping it, you could spread a layer of hydrated lime to 'boil' the fish and the unwanted vegetation seeds, roots, etc. The lime will raise the ph quickly and kill the fish and vegetation. ph will drop back after a couple wks. I would first rotenone to kill the fish. I wouldnt save any fish for stocking. They are too cheap to buy known pure varieties.
