Kelly thanks so much. Interestingly, it appears the next few weeks in the Richmond,VA area will be like April. Lets say I draw down in a week, mechanically remove, spray area, and after pond refills in the spring apply aqua shade to prevent sun light from reaching the bottom. Does this make sense. I swear it appears this stuff has gone nuts in the past 2 months. February 2011 hardly any, now its 30 plus percent taken over.
