I am very sure where this stuff started from and I would like for you to just think about it. Have you ever used Round-Up or a product that is similar to kill weeds on your driveway? I believe that is what started our Blue Green Algae problem. Something to think about!
I want to make a suggestion and I believe I am right, Have any of you use round-up on your drive to get rid of weeds? I believe that there is a direct correlation between the Round-Up and the Blue Green Algae.
