Hello Jkross and welcome to the forum.

I've helped hundreds of guys on the forum with leaking ponds, and have sealed 7 of own, happy to help if possible.

Some wicking is natural for a new pond, but that would likely not be responsible for 12" loss. Measure your vertical water loss daily with a stake - this is critical data to establish.

Bentonite, in my experience and the pond builders I know, will not seal a hydrated pond. They use bentonite during the construction of liner phase. Sealing hydrated ponds can be achieved in other ways, however.

If you would like to chat I'm happy to spend some time learning about your pond and possible leak issue. My time is free to my Pond Boss family. Feel free to reach out anytime:
