Okay, I've looked all over, but can't figure this out. I like the idea of making a corner pond for drainage and aesthetic, but I do not understand how to go about constructing one. I've seen "slope the false bottom" but that's it. What do you do with your substrate, or substrate barrier? is there something to keep the water in the pond away from the substrate? should it be lined with anything? help, I am thoroughly confused! If anyone has photos of theirs, I would love to see. Thanks!
