Good news, after about two weeks it just turned loose and floated out into the pond. I treated the deep area of the creek and it responded quicker. It has rained some in the last week and a lot tonight, so I will hold off treating the pond proper until the flow slows down. My pond flows over the damn into Lake Waxahachie so I try to be careful about run off. The pond look a lot better, but the rain usually "beats down" the problems and appears to clear up for a few days...
