I want to add some bentonite powder to my pond to try and stop the leakage. The pond is about 12,ooo sq ft surface area and is loosing about 2-3" each day. I realize that some of the water is lost to evaporation but there is also water under the liner. I'm hoping that the bentonite will help slow or stop the leakage. Question is will the bentonite be harmful to the fish-LMB,BG,CF and any idea of how much bentonite may be needed? Any other remedies that may help??
