I agree to use a recycled or used billboard tarps as pond liners. As I saw the great review on used billboard tarps here - http://tarpsworld.blogspot.com/2010/03/building-fish-pond-using-used-billboard.html, I realized that the used billboard tarps can be the best alternative use as pond liner. Thanks to this thread.
