Yes. One high-volume aerator will clean a pond deeper and wider than six 1-horsepower aerating fountains. This is because one aerator controls 6 subsurface diffusers. The pond is divided into large zones, each with a diffuser. Diffusers emit powerful columns of bubbles which mix your entire pond by hydrodynamic lift force. Kansas Department of Wildlife Parks & Tourism A neighborhood pond is a couldron filled with road chemicals, fertilizer, leaves, trash and runoff. As such, both the EPA and the Kansas Dept of Wildlife Parks & Tourism recommend subsurface aeration as the #1 way to improve pond water health. We have 25 years experience selling & installing aeration, with 3 disciplines: biological, chemical & mechanical filtration. While a fountain will freshen the pond surface, aerators scrub your whole pond from bottom to top. In short, aeration controls pond scum, algae, fecal coliform, decaying leaves and fishkills.
