Hi, did you ever get an answer about winterizing your pond? I live in Dunnellon, FL and this is my first pond and wanted to know pretty much the same info that you asked about. I know in the north you need to get rid of your floating plants, but I got mine out of our local river so I'm wondering if they will survive the winter down here. If you got any answers or if you found out by going through winters down since your post in 2007 here, what we need to do? Will you please share the info with me too? Thanks, Misty
