YITAHOME LLDPE Pond Liner 20x20 ft, 20 Mil Pond Liners for Outdoor Ponds, A Liner for Fish or KOI Pond, Waterfall, Fountain, Bed Planter, Pliable & Durable

Strong and heavy

Superb quality found in buying this pond liner. Our previous one had a hole in it and began to leak. Upon unboxing it was easy to see this is made from top notch materials. We've actually had it installed for awhile now. It was moldable enough we could use it on the waterfall effects also.

This liner was incredible. Very well built no weird, oily residues on it didn’t have to clean it before I use it very thick and durable. I can see several years of use no leaks even with rock on it. This is the right product for you if you want a heavy duty durable liner, you found it now you order it, you’re welcome. Have a good day.

I bought this liner for my Koi Pond. Installed it and has a leak in it. Did not last 2 months.

Order for my pound one solid sheet came with tape Incase needed for modifications or repair was folded in a way that made It easy to unfold did by myself this is a very stiff plastic and definitely recommend doing this when hot or in the sun so it flexes easier was advertised as good and meet all I expected I’ve never used a pound liner before and was fine useing it

Very thick and long lasting safe for my fish and don't have any more leaks to deal with. Highly recommend using this for your koi pond. Also works great for a slip and slide game for the kids. We cut off the access and use it for water slides in our yard!

2 years ago, I ordered an HDPE type liner...not expensive, but the irregularities of my pond had me about 18" short. It was OK to work with, but a bit brittle....after 2 years, it seemed to get some leaks....SO< I took it completely out, cleaned the pond, redug some areas (btw, my pond is 1600g). I lined the entire area with carpeting again as underlayment and put the old patched liner back. But, I bought a bigger LDPE liner, this one. The reviews are OK, I would say this one was easier to work with than the HDPE...so, I would say, between the two, buy the LDPE for the same funds. It went down ok in 70* weather, wish it was warmer. I am filling it now, looks OK,....less seam overlap than the HDPE type. (I decided against the PE, as everyone kept saying they were tarps, but some of them are rated better). If you have the money, get EPDM/Rubber....if not, LDPE is good. PVC is very difficult to work with if your pond is not regular shaped. ..>>>>>>>>>>>>>>>>>> I will update if any problems after full installation, but it is filling now and seems ok all around. UPDATE// WARNING: Every fish, every tadpole, every frog died when put into the finished pond!!! The installation was as posted earlier...fine. I kept the liner out in the sun, spread out, for 3+ days....it took me about a bit to get it all installed. I filled it while I was finishing the rock border. Let the water stand 4 days (most of it was rain water, as I have two house gutter spouts directed to the pond). When I put the fish/frogs/tadpoles in last night, ALL OF THEM are dead this morning. I had them in a 130g stock watering trough. They were all alive. EVERY fish is dead. I will wait another week, and then introduce some small goldfish....... BE WARNED.

Great pond liner will definitely buy again
