For those that dug their own pond, which liner did you use?

I'm digging a 150g goldfish pond and I'm pricing out liners. The fancy 45mil rubber liners are significantly more than the liners you can get at lowes or Home Depot. What did you all use and is the extra money worth it?

I havent done it yet... but plan to. I wouldn't skimp out on the lining. Also look into laying some sort of padding, like old carpet, down first.

Yeah I'm definitely gonna do an underlay meant. I'll probably go with the more expensive liner. Might as well not cut any corners.

i'd rather spend more now, than spend double later.

that being said, I'm pretty poor at planning... so i make up in it for spending more multiple times before the project is done.

I went the cheap route and used a billboard tarp, 17 ml thick.

Put it in with old carpet as a liner last year and so far so good.

I would use EPDM 45 mil if it's not out of your budget. It would be more trouble in the future if you go with a cheap liner and end up with a hole punched in the bottom and have to replace it which would mean taking everything apart. I used 45 mil with underlayment when I put my pond in over 12 years ago and have not had any issues. I put a smaller pond in at my mother-in-laws and used the cheaper liner that you get from local hardware stores and needless to say it has been replaced twice now. So if you want it to last don't skimp on the liner.

Dropped the hammer and wound up getting the EPDM 45mil Firestone liner. 20x20 with underlayment set me back 400 bones with shipping.

Went cheap the first time, then replaced it.
The Xavan option is not worth it. While it is a bit thinner, it is not significantly better at getting into corners. I am not saying it is no good, it is holding up just fine. (10+ years) Just saying it is not worth extra money over the 45 mil EPDM.

We use 45 mil EPDM now. With padding. Easily available from 2 local suppliers in many widths so whatever size pond we create we can get the width we need.
The padding we use is a heavy duty filter fabric that is used behind retaining walls to keep dirt out of the gravel backfill. This is a thick felt-like material. I have carpet under my own pond.

The liner at HD & lowes work fine. Walmart has one too. Make sure to put down an under layer so rocks won't puncture the liner. Just in case there is a leak, don't put the pond near (10 feet) your house.
