First of all, we love the pond... It is an asset and we'd like to get it healthy enough for fish... Right now it's just supporting about 12 turtles and about a hundred frogs...
It is not spring fed, however, so I am considering digging a well and pump up water to feed it...
I checked out your sire, maeve... It didn'e say anything about killing duck weed but it sounds like something I need to do anyway...
