Wish my update was as good as belkins456. We've had some good rain and my pond level is just about 'back' at the same level where I applied the 18 gallons of the DB-100. Now I'm starting to see seepage again at the toe of the dam. I've been skeptical since the application of the DB-100 because the water level continued to drop but the seepage at the toe disappeared. I've also had fixmypond's post in the back of my mind the whole time. Seems like maybe there is something to what the one post wonder said about the DB-100 not holding the seal once the water level recedes and then returns. Or... maybe my seepage was not fixed by the DB-100 and the reduced head pressure from the lowering water level did the job. In any case, I'm going to keep watching it to see what happens next so I can come up with another plan.
