I’m sure this has been answered many times so if you can send me to a “thread” that talks about this topic that would be great.
I have some koi that I have raised in a 3 foot deep, 4 foot circular lined pond for the past 3 years. Time to enlarge. I have researched several types of pond linings. I want a light one so I can see the fish. I was thinking concrete but that is a lot of work on my part so…having a back hole come in and digging out a nice size whole and sealing the “clay dirt” – that is what we have around here. Now…what do you seal a pond like that with so the water won’t leak out? I have heard of “lime” (? I think that is what she said) and then there was some kind of clay you can have brought in…it starts with a B – like betadine clay or something like that. Thanks for any suggestions???
