Winter Operation Considerations
During any season, the EnhanceAir™ PRO Kit will provide the necessary oxygen to
your pond to promote happy and healthy fish as well as greatly enhance the biological
ecosystem that keeps it clean and clear. In the winter months, though, an aerator not
only provides oxygen but is 80% more energy efficient than typical floating heaters and
equally effective in keeping an area of the pond from freezing, allowing the necessary
transfer of harmful and beneficial gasses.
Following are precautions and recommendations when using your pond aeration
system in the winter months:
Diffuser Placement:
In warmer months, the best place for the diffuser is in the middle of the pond near the
deepest point to circulate highly oxygenated surface water down into the depths of the
pond (Figure 1). However, in winter the pond’s surface water is super-chilled from the
cold air and should not transfer to the bottom of the pond where the fish are. For this
reason, it is
extremely important
to move the aeration diffuser to an upper shelf level
near the pond surface in colder weather (Figure 2). Place the diffuser so that it is 6” to
8” below the water surface. This will keep the super-chilled water from circulating to the
bottom of the pond as well as create greater turbulence at the water surface to keep an
area from freezing. Note that the ice all around the opening is thinned and will not sup-
port weight, so never walk or step on the ice. When the pond is used for recreation in the
winter, clearly post signs at or mark the location of the diffuser and thin ice at the surface
to warn any individuals on the ice.
