Setter, I know what you mean...I tell people my pond is "going dry" and they think I'm crazy. But when you stare at that thing EVERYDAY, and know what you are seeing, its a little aggravating. I'm at about .5" a day...little less when cool. I'm not happy there...would love to slow it down...but like John says...maybe it will slowly seal a little more over time. Its not but a couple years since we worked it and its not gone dry since then. It did the couple years before we worked it. Its young...but isn't it great to see it full!
