My wife and I built our first stock tank pool today and used this liner to avoid rust issues down the road. We placed this liner in the sun for a couple of hours to make it more pliable, laid it in the pool and filled a couple of inches initially, working out any creases or uneven spots. We then filled to our first hole for the sand filter pump, cut the liner with an Xacto knife and continued until we were happy with the water level. The weight of the water displaced all of the air and the liner fits like a glove. We gently pulled the liner over the edge and downwards as it filled and it looks perfect. There is enough overlap/excess to cover the sides of the stock tank to the ground if you want to have it finished looking. We like the style of the steel sides so we got a 20 foot black ratchet cable and cinched it in place about four inches from the top. Trimmed the excess and couldn’t be happier with the final product. The liner looks and feels great. No rust from chlorinated water on galvanized steel and no breakdown of the stock tanks factory installed seam seals. Worth every penny! Also for stock tank users - be aware stock tanks ship in sets of three (sort of Russian dolled/nested inside each other). The outer tank is slightly larger than the other two, the middle is slightly larger than the innermost. We grabbed the middle tank because it measured a true 96 inches.

Used for 8ft round metal stock tank. Some minor wrinkles when put in. Has held up an entire season and still looks great. Looking for many more seasons of use

I purchased this liner for our 8 ft stock tank pool, which had started to rust. The liner fit perfectly and was easy to install. The sides were very long and I saw videos where people either cut it all the way around to shorten it or they left it long and folded it under at the bottom, I decided to do the latter as I wanted to make as few cuts to the material as possible!

We purchased this pool liner for our stock tank. Nice color, nice material. It could be our error, but after installing, tightening and filling with water, after 1 week - the liner stretched. Leaving with bottom with creases and air as well as the sides.

Why did you pick this product vs others?: Used to line a 8ft Stock Tank pool after epoxy liner failed. 1st season, but looks great. Has plenty of liner material to fit up to a 4ft deep pool. Seems relatively thick and sealed around the filter jets great. So far so good.

We used this liner for our 8 ft round stock tank “pool” it’s a perfect liner!! It was super easy to install. I highly recommend watching a video on how install as well as recommending to lay the cover out in the sun to warm it up and allow it to stretch
