I have two ducks currently habitating two walmart kiddie pools. As ducks, they dirty it rather quickly. I'm very small and unable to keep flipping it day by day. I have an area I was planning on using this summer for a new pond and butterfly bush and things. I'd like to have a homemade filter such as the one on the "my duck pond" thread. I've looked into duckponics and considered putting duckweed in the top of the barrel and putting some mesh over the top so the sweet ducks can only eat what overgrows it's container The problem is I have no electricity out there, and no safe way to supply it. I'd almost given up hope when I read something about a solar powered pump. Does anybody know anything else about this? I'm very limited as far as budget goes. Should I dig a pond or bury the pool? Any suggestions for my particular scenario?
