Review on 16X20 Ft 20 Mil Thick HDPE Rubber Pond Liner For Outdoor Ponds, Fountains, Waterfalls & Water Gardens by Jay Matlock

4/12/2020 Update to my original review- After CAREFULLY installing this liner for my 1500 gallon pond with 20 fish while making sure nothing was under, around or in the pond that could possibly cause a puncture, it still managed to spring a leak/crack somewhere and lose water. The water level goes down almost 1 inch per day and it's not hot here yet. I removed the waterfall to make sure it wasn't evaporation as well. I had to spend 125.00 for the liner plus 400.00 to have it professionally installed. NOW I have to purchase another liner and pay to have this one removed and a new one installed! It's in the ground so it's not like I can return it for a refund.ORIGINAL RATING: It’s very stiff and almost brittle. Easy to puncture.
