Glad you mentioned my pond and WM and DW problem. It's right at 2 months by a couple days since I treated with Sonar, its looking great! I went ahead and had a second treatment of 6 oz. I think just to make sure,One week ago, I was seeing a few specks here and there of the WM and I didnt want to get it started again. This is a picture I took with my camera phone and it is low quality but I think you can still see what it has become, I love it!
