15 x 20 Feet Pond Liner, 20 Mil Pond Liners Black HDPE Pond Skin, for Outdoor Ponds, Water Gardens, Waterfall, Fountain, Fish Koi Ponds

Durable, and sturdy pond liner. It will get algae growing if you have it in heavy sunlight. Good price, and won't leak.

It is exactly as described. It is a 20 mil waterproof tarp. I used it for an outdoor pond for goldfish. Worked nicely.

Perfect for my outdoor fish pond

The media could not be loaded.  I had plans for 2 ponds, one flowing into the other. I installed the first pond and the next morning the water was gone. I decided to go with one pond instead and installed the 2nd liner. Again, water level kept dropping. I tried again with the first liner thinking I might have missed something, and you can see by my video I have at least 2 leaks. I was very careful with installation and I had foam between the rocks and the liner, so the rocks didn't cause it - not that it should matter anyway. It was exhausting and a waste of time and money having to rip out and reinstall these liners, which just seem to be coated tarps.I would like my money back, but I did cut these liners to fit my pond, as most would. I'm hoping they are still returnable.

I've ordered several different 20 mil thick HDPE pond liners as I've been troubleshooting my dam, and this one is notably thinner than all the others. It would be easier to conform to shapes if that is what I needed to do, but that is not critical for my use.The thinner material seems to hold sufficient water back, however I question its longterm durability.

Very nice tarp heavy duty for pond thick but i had no need for it so i returned it

After it was installed in my pond and water added. There were daily dead frogs in the water. Glad I didn't put any Koi in yet. Will have to reline.

Super thick and is what is stated.Would buy again.
