To ensure the success of a large lake or pond, the most important consideration is, arguably, proper aeration. In a pond’s ecology, dissolved oxygen is critical. Not only is it what makes a pond go, it is also what contributes to clean water and healthy inhabitants. The most immediate problem that is attributed to low oxygen levels in a pond is fish kill. And since fish require a certain amount of dissolved oxygen in water to thrive, without it, well, they eventually die. Diminished levels of oxygen also lead to noxious odors emanating from the pond. This is because the aerobic process of breaking down organic waste shifts to the slower anaerobic process whose end product is hydrogen sulfide. In deeper ponds, lack of oxygen leads to stratification meaning that the lowest layer in the pond is likely to be un-usable due to extreme oxygen deficiency. This also has the effect of reducing available pond space within which fish live and further straining the remaining oxygenated water. A proper pond aeration system thus provides numerous benefits.
Fish kills as a result of low levels of oxygen are reduced and can even be prevented. To break down wastes efficiently and reduce the murky bottom layer, beneficial pond bacteria are stimulated to facilitate the process. Further, problematic anaerobic bacteria are out proliferated by aerobic bacteria resulting in odors being controlled. Metals such as iron precipitate out and key nutrients such as phosphates become unavailable. Algae blooms ultimately become less problematic and less severe owing to the lack of available nutrients.Hydrogen sulfide and carbon dioxide gases can be vented.Pond water de-stratification leads to improved water quality and prevention of turnovers. The pond’s natural regulatory ability to regulate diminishes the use of maintenance products. As for ponds in areas that experience heavy winters, pond aeration systems prevent their surfaces from freezing over thereby allowing gaseous venting and preventing fish kills as well. With all the benefits pond owners should look into getting and aerator or pond fountains for a healthy pond eco-system.
