Cheezy1963 - I found DB-100 & the PondDoctors web site via the internet & google - just searching. I found multiple products - like Ess-13 (really expensive. Candidly - the only reason I went w/ DB-100 is because the guys called me back & talked to me...couldn't get a call back from some of the other shops.
With regards to Dave Davidson1 - as I understand it (and I have seen it) - if you just take the liquid and drop it into the water it forms a gooey ball - that sinks. But I think because there is not much agitation of the water - the ball doesn't get very big - therefore the probability it hits the hole probably isn't good.
When I applied it we had a 300+gal brine tank on the back of a truck. You are supposed to mix it 500:1 - min. One half gallon of the stuff turned that entire brine tank into a jello like consistency. We took a 2" trash pump and sprayed it - on the bare banks - we drained the pond pretty much. Even in this jello form - it sinks - you can see it.
Good luck gentlemen - I am interested in what happens.
