Surface fountains are a popular choice when decorative looks are desired. Golf courses, parks, office buildings and housing developments are all common places you see fountains used. Many different spray patterns are available creating aesthetically pleasing looks while creating circulation and aeration. Since the fountain float on the surface, the circulation does not reach all the way to the bottom in deep applications which reduces their effectiveness.
Since fountains do create good water movement at the pond's surface, they are helpful in keeping pollen, duckweed, watermeal and other surface debris under control.
