I am renovating an old pond. I have got it cleaned and dried out. I have heard good things about bentonite, but dont know anything about it. Where can I buy it, how much should I use, how do I apply it, will it stay on a steep slope (2:1)??? Pond size is 1/4 acre, 14' deep, soil type is silty/small rock upper portion and the bottom is more of a bed rock/decomposed granite.
