Thanks....In the upper right of the picture you can see my neighbors small pond with an island. It is fed by a seasonal stream and that is where I pump from.
Hoping the DB does the job. I plan on using no more than 24 gallons which costs right at $1,000, plus may use bentonite with it. The quoted price for ESS-13 was $6,100 plus shipping and I cannot go for that at this time.
