I was wondering if anyone has tried using this product in their swimming areas, and if so, how does it perform in keeping the weeds out? Here is the link: http://www.lakemat.com/

I have been trying to keep chemicals out of the pond as much as possible, so I am interested in this, but I also wonder if I could spot treat the swimming area with SonarQ and do a better job. Any ideas?
