belkins456, are you measuring the vertical water loss? I never had much luck with really measuring the water as it recedes down the bank. You may get a better idea with a yard stick in the water or something. Did you notice if your water cleared any?

It has been 24 hours since my application of 4 gallons of the DB-100. The only change that I noticed is that my water is just a bit clearer. Went from 5 inches to 6 inches. Was pretty simple to apply with a 3 inch trash pump and mixed very well. One thing I would note, don't let the pump run out of gas. It is very hard to get primed with a pump full of DB-100. I will wait a few days and apply some more.
