Maintaining adequate dissolved oxygen (DO) levels in water is a critical component to sustaining healthy ecosystems in lakes and ponds. Low DO levels and the presence of excess nutrients such as nitrogen and phosphorus give rise to unhealthy water bodies. Low oxygen at the bottom of water bodies can cause additional releases of nutrients from the sediment, further degrading water quality. Sustaining DO levels across the entire water column increases ecosystem health and helps reduce the recycling rate of nutrients into the water from the sediment layer.


     We work with manufacturers of both types of systems. An oxygenator is ideal, however, not always feasible or affordable. Aerators, the name is a misnomer, is really a circulator, and while often sufficient to mix oxygen rich surface water to the lake or pond bottom, it also can have some negative or unintended consequences. Fountains, are not really aerators, though they do increase Dissolved oxygen in a localized are.

Oxygenation or Aeration?

What's the difference?

The term "limnology" is derived from the ancient greek word λίμνη (limne) meaning lake or pond.
