Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants Pond draw down when applying sonar

Fish Head
The best way to treat a pond that has flow through is to draw down as much as you can. I would take the amount you would be normally applying and only add 2/3 to the pond. I would then add the other 1/3 about 3 weeks after the original treatment. That way you are keeping your concentration in the pond for an extended period and will eventually starve the target vegetation.
