I was surfing for ideas and came across this: http://www.evl.uic.edu/aej/pond/index.html. (56K beware)
If you scroll down a little you will see what they did for an indoor pond. I really like the shape but was wondering if those pond liners can handle being above ground like that. Supporting the bottom is easy enough but I would worry about the sides bowing out and eventually breaking. Any thoughts?
