Cheezy1963- I will put a yardstick in it and measure it that way. My water definately cleared quite a bit. I had some floating algae on it and it seemed to clump it together and force some of it the bottom. I'm just still unsure about the sealing principles of product but maybe I haven't give it enough time to dillute entire pond yet?

The trash pump definately seems like way to go. Did you get any product on your hands? Slick stuff huh!
