Pond Boss Forums POND CONSTRUCTION Selecting a site Surface Aerator

That depends. If you can send me a sketch of the pond with the depths roughly outlined and where the electric is, I can then figure it out for you. How many all depends on the shape and depth of the pond. For instance two rectangular ponds that are the same depth and same size, but one has an island in it? The one with the island will need more airstations than the one without.

Will your pond freeze for more than a few weeks at a time? If yes, then we need to plan on winter aeration.
