I am new to the forum and my pond developed a leak along the seam (I didn't seam it right the first time) so we have pulled the liner out and I am reseaming it. While we have the liner out I am thinking about making a couple of changes but I'd like advice about them first. The pond used to be lined with retaining wall bricks that I used to make a level surface and have something to lay the underlayment and liner on top. My husband wants to use the retaining wall bricks somewhere else and thinks we don't need them - that we can lay our big flat rocks right on the dirt to hold the liner down. Also I was thinking about putting in a fountain with a short little creek that flows into a bog type garden and then into the pond. I don't know if any of this makes sense but if not maybe you can ask me questions that I can answer to make it clearer. Thanks.
