DB100 report, I started pumping DB100 into the pond on friday afternoon. Doug from pond doctors suggested putting in half now by the Dam where I have the leak, and the other half in about a week.
The pump was a 1 1/2 HP 1 inch 2stroke pump and it was run at half throttle and the flow valve was only slightly open to keep a small amount of db100 mixing with the output.
It took 3 1/2 hours to pump 3 gal. cause I reasoned a slow mix would saturate the Dam area best. I also would alternately put the hose deep to stir up silt to combine with the product.
I feel it's too early to have a positive result yet, and it is too hard to tell anyway as starting Sat. night it rained hard, and also on Sun. & Mon., and the dam is wet from the precip.
I will be going back up to the pond in a week and pumping the rest of the DB100 into the pond, and in a few weeks I will report on the results.
