3.5 acre pond transformation took approximately 1 month...Algae cannot come back!

To whom it may concern,

We decided about three years ago to have a pond dug in our back yard. We had a man dig a pond 50' x 50' x 20' and from about a month after it filled, green algae. I did everything to clear the pond, but nothing worked. The type of algae we had was planktonic and the pond looked like a bowl of green pea soup. I had just about given up and thought of filling the pond back in, but my wife did some research on the internet and found ultrasonic. We contacted the people at LG Sonic and purchased an XL sonic unit from AlgaeControl.us in Charleston, South Carolina.

I tested the water every two days by taking a sample in a 1 gallon clear container and after about twenty days the green in the container turned brown. We have had the unit for one month now and my pond is very clear.

Thank you, LG Sonic
