We are very satisfied with our Vortex Filter system. The morning after the first big storm the bottom of the pond was covered with leaves. Within two hours, the pond was clean! We love the clarity of the water and the very low-maintenance. I would recommend this system to anyone who is thinking about a pond. Terry, Napa CA
