Beespringky- Why didn't the Miracle gro sprayer work? I sprayed 12 gallons and had no problems with mine. You just have to turn it upside down occasionally go keep the sprayer unclogged. I hope you didnt try to use the green fan spray tip that comes with it. That will clog! You have to make a custom spray nozzle on end of miracle grow feeder. Good luck with your leak. I'm about to break down and try some db-200 as one last attempt to get my pond full.
