Fishes and other aquatic creatures thriving in an artificial man made pond requires significant oxygen content during certain months of the year. During the summer months, the scorching heat reduces the oxygen levels in the pond, thereby depriving the pond inhabitants of the much needed oxygen. The reduced oxygen levels result in the reduction of immunity strength of the aquatic creatures living inside the pond. When the immune levels get weakened, the aquatic creatures loose their disease resistance capabilities and die a slow death. Some aquatic creatures might not perish. Instead their growth would be considerably affected. Pond Aeration is a technique by which the oxygen levels are enhanced inside the pond atmosphere.
Different Pond Aeration Methodologies
There are two ways in which pond Aeration can be achieved within a domestic pond.
1. Bottom Pond Aeration
2. Surface Pond Aeration
Bottom Pond Aerators
In Bottom pond Aeration methodology, Diffusers are placed at a suitable depth level from the surface of the pond. Diffusers are used to circulate the water present deep inside the pond to the pond surface. The placement of diffusers play a vital role in effective dispersal of water to the pond surface. Diffusers should be installed in the pond, where the depth is the maximum. When placed at the deepest point in the pond, the diffusers would be able to push the maximum amount of water to the pond surface. This would ensure proper supply of oxygen to the water present at greater depths. The water then again goes back to its original depth after having absorbed the required oxygen content. The oxygenated water continues to enrich the lives of the fish and other aquatic creatures living deep inside the pond.
If the diffusers had been placed at shallower depths inside the point, the water at extreme depths would be deprived of the much needed oxygen. This would reduce the living space available for the aquatic creatures living in the pond, as they tend to avoid the deeper sections in the pond. In addition to increasing the oxygen levels, bottom pond aerators also help in maintaining the temperatures at optimum levels for the aquatic creatures to live a comfortable life . Paddle wheels are usually used to disperse the water to the pond surface. With advancement in manufacturing technologies, aerators are far more quiet and efficient, these days, when compared to the aerators that were in vogue some five years back. Bottom pond Aerators are ideally suited for ponds with uneven depths.
Garden Pond Aerators
For a pond with even and shallow depths, surface pond aerators are tailor made for increasing the oxygen levels. garden pond aerators work by pumping the pond water to greater heights and then allowing the water to fall into the pond. The water comes back to the pond in the form of a waterfall or a fountain.
Water fall based Surface Aerators
This is a popular form of surface aeration as it enhances the look and feel of the pond structure. In addition to improving the aesthetic aspects surrounding the pond, it also helps in regulating the temperature and increasing the oxygen levels inside the pond. The water from the depths of the pond is pumped to a particular height from where it gets dispersed in the form a waterfall.
Fountain Surface Aerators
Unlike the waterfall aeration, water at depths inside the pond are dispersed in the form a fountain and are allowed to fall back into the pond. The pressure applied to pump the water is slightly less than the pressure required to pump the water to reach the top of a waterfall. Similar to the waterfall aeration, Fountain surface aerators also improve the aesthetics of the region surrounding the pond.
1. Water in the depths of a pond are rich in bacteria that aid in maintaining the pond depths in a healthy condition. By implementing Pond Aeration, these beneficial bacteria get a new lease of life.
2. As mentioned in the earlier sections, Aeration increases the oxygen content at various depths inside the pond. This provides a greater living space for the fishes and other aquatic species, which would eventually enhance the life span of these species.
3. Aerators also help in preventing the growth of algae. When allowed to grow, algae affects the health of the aquatic species living in the pond.
There are a number of pond aerator installers available for selection. One has to look at the past credentials of the Aerator installer and go through the online reviews received by them, before choosing a particular aerator installation and maintenance service provider.
