Pond Boss Forums POND CONSTRUCTION Selecting a site Surface Aerator

Otterbine makes quality stuff, but if the pond is going to be deeper than 6-7 feet then the surface aerator needs to have a tube that pulls water from deep in the pond. Surface aerators put more O2 into the water than bottom diffusion aeration systems in shallow ponds but at a cost due to the electricity and motor horsepower that is required to operate them. In a pond that was 10' deep a customer had a surface aerator without a draft tube, so we installed a Vertex bottom diffusion aeration system. He ran both systems and the O2 levels in the pond were running 120-150 percent saturation level in the hottest part of the summer.
