Oh thats what I did wronge!!!!I have another question Greg. My pond is 3/4 of and acre at about 15foot deep. Thats at the deepest dept according to our neighbor. I know it drops about 6 ft after you get a couple ft from shore. How much white cap would I need and is it better than sonar? About how many times will I have to apply it? About how long will it last after I get the watermeal cleared out?
