We started using Aero a little over 8 years ago on our 2000 cow Dairy Farm to help with odor management. Aero has helped to minimize odor very noticeably. An added bonus of using this product, we have seen a drastic difference in dissolving the suspended solids and not allowing for sediment buildup. Which has resulted in a considerable decrease in the cost of maintenance of cleaning out our lagoons. Because of Aero, we save many thousands of dollars per year. We recommend it to everyone in our business!
