Lifeguard 10 ft. x 20 ft. EPDM Pond Liner – 45-Mil Rubber Liner for Outdoor Ponds, Waterfalls, Aquaponics, Retention Basins – Durable & Fish Safe

I purchased this liner for my Koi pond. It seemed nice and thick out of the box but was covered in some sort of dust that I assume is from the manufacturing process. I rinsed the liner off prior to installing but the dust did not come off until it was installed and the pond was filled with water. Long story short the dust became suspended in the water and and even after filtering it ended up killing 2 of my Koi and the others are very sick and could still possibly die. Very disappointed in this product, especially since it specifically says that it's safe for wildlife. I would use caution if you are considering using this product for a fish pond.Update since I posted this review 4 more of my fish have passed away. Would give 0 stars if I could.

I didn’t read the reviews concerning dust on this product - it probably is used to prevent material sticking together. It must be scrubbed off prior to use. I didn’t, and I am on my third water replacement trying to eliminate the contamination. Product itself is as described, and is very strong - just this inconvenience of preparation prior to use.

Extremely happy with my pond liner. I bought the 10x15. I’m happy with how easy it was to install. I’m impressed by how durable it is. I’ve used large rocks on it and no sign of wear. My pond is not complete yet, but I couldn’t be more completely happy with my liner. Thanks so much!!

After researching, i decided on an EPDM liner, then eventually chose this one. My pond is about 7'x10' (kidney shaped) so I chose the 10'x15' liner - thinking it was going to be much too large, but it turned out to be just the right size. The material is thick and heavy, and seems like it will last a long time. As with other reviews, I noticed the liner was covered with dust - maybe from manufacturing? maybe for shipping so it doesn't stick to itself? Whatever it was, there was a lot of it, and it's not easy to remove. I laid mine out on the yard and hosed it off, then mopped it, then hosed it again, then mopped again - and did that for both sides. Because I was replacing an old liner, I already had fish and wanted to get them back in the pond ASAP, so the liner went in on Sunday and the fish back in on Monday - no issues so far (it's been about a week).My last EPDM liner lasted almost 20 years, and would have lasted longer had I not punctured it. This liner seems of similar quality.

I bought the 8'x10' version and was hoping that it was exactly 8'x10'. Unfortunately, the actual dimensions were 7 ft 8 inches x 10 ft 4 inches which didn't work for me since the raised pond I built needed it to be much closer to the 8'x10' dimensions. This was an error on my part for building a pond to fit the pond liner exactly. I contacted the seller and received a response the following day. I was given the option of either getting a full refund and returning the item or getting a 50% refund and modifying my pond. I did not expect the seller to immediately offer both a full and 50% refund so quickly with no questions asked.My advice is to not follow in my footsteps and buy a pond liner to exactly fit your pond, but instead, buy one that will have more and enough overlap. The pond liner was extremely well made and I am more than happy with the product. I am especially happy and appreciative of the customer service.Highly recommend!

Perfect for adding on to my existing pond with waterfall.

I clean koi ponds and this is about as tough a liner as they make. Ive taken sharp edged 1 man boulders and dropped on scrap pieces to show its durability to customers. Ive bought 3 liners for installation and not an issue nor defect.

The pond liner arrived both shorter and narrower than advertised. It was obviously cut from a larger bulk roll and the cuts were not straight. It also arrived with a slit in it.

I honestly haven't installed this yet as my project has been delayed. However, having purchased and installed similar liners in the past, I was impressed with the flexibility and quality of this one. I'm sure it will install easily, and hopefully last a long time
