"Thank you! The gate arrived yesterday. Please pass on my thanks and appreciation to the artists, welders , logistics team and all who contribute to fulfilling my order - the craftsmanship is exceptional and the materials used will last multiple generations. In a day when one can buy a product on Amazon, get it in two days and then watch the paper thin materials rust to disintegration in less than a year, it is great to know that there are still artists in America making high quality products by hand that will last past my lifetime. Well done!"
I purchased this little wading pool at the Dollar Store then lined it with 6 ply plastic that I found in the flooring department at Lowes. You can also use black plastic and it can also be found in 6 ply.
You can use heavier products which I would recommend for a longer fountain life. Fish Ponds stores carry heavy black liners that you can lay over cement blocks to build the reservoir.
