I built a pond out of landscape timbers and plywood and now need something to put under the 45mm liner. I have heard carpet, but would cardboard work? Lots easier to work with.
By the way, I found a 15 by 15 Firestone Pondgard liner 45mm at BestNest.com for the cheapest anywhere on the Internet, 104.00 including shipping and they got it to me in 2 days. Sweet.
