I called and talked to Doug at Pond Doctors today and he did mention one thing that may help this product seal if you have a failed attempt. He said apply dusted clay or bentonite during the application of the DB-100 and the materials "clump" while in suspension and settle, then swell hopefully in a point of leakage. Also, he recommended placing an inlet barbed "y" fitting in the suction hose of your pump. The pump suction hose is placed in the pond and siphons the product, which could have the volume regulated by a valve in the hose between this fitting and the DB-100 container. Then just tug the discharge hose around to disperse the mixture. Good luck,please keep us posted and I plan to order mine soon to give it a try!
