Thanks for your response guys. I have recently just sprayed the pond for the first time. I used 2 gallons of tsunami, 8oz of clipper, 3teaspoons of surfactant mixed with only 2 gallons of water. Like you, my dad was able to borrow a 15gallon battery powered sprayed and that baby sprayed a little to quickly imo.. We ran out of spray really quickly being that we only added 2 gallons of water, but that is what Andrea at Sanco industries suggested. After we ran out of spray so quickly, I started to get a little depressed. We barley made it around the pond once. I later called Andrea that day and she said we were moving to slowly, but we would still be surprised with the results. I can tell we did make a dent in the duckweed as there are parts all over the pond that are turning brown. We used a paddle boat to spray. I was moving us along while my dad was spraying from the back. I am going to spray again in 10 days with a similar mixture. I may add a few more gallons of water, but Andrea said I needed to come out with guns a blazing. I surely will be moving a lot quicker next time.
