Aerating a Pond
The importance of properly aerating a pond or lake cannot be overstated as, without proper aeration a pond or lake will stagnate and become unsightly and smelly. Unlike a river or stream which is continuously moving and therefore the water comes into contact with the air at the surface, a pond’s water does not move meaning that only the water at its surface can receive oxygen via the air. As the pond ceases to get enough oxygen, the fish will start to die and algae will start to thrive. It is this algae that makes the pond unsightly and it also gives off an unpleasant smell. To keep a pond or lake aerated, an aeration system needs to be fitted and the type of aeration system that should be used will depend on the depth of the pond as there are different ones for shallow ponds from the ones needed for deeper ponds and lakes. Among one of the most popular aeration systems for the shallower ponds are fountains. Often people think that a fountain is only placed in a pond in order to beautify it but most fountains also serve a more practical purpose. As the fountain throws water into the air, that water can be oxygenated as it has contact with the air and as a circulation of the water is also formed by the fountain, all the water in the pond can be aerated properly. A pond aerator 2016 may even include a floating fountain. Often these floating fountains with come with a variety of decorative heads, allowing the user to display their own sense of style in decorating their pond. These are particularly useful if you have a large pond as you can buy several and by using different heads, make a pleasant scene and probably be the talk of the neighbourhood. Of course though, although fountains are popular there are other aeration systems available. For the shallower ponds there are propeller systems. With one of these systems power is used to rotate propellers which are placed at the surface of the water. As the propellers spin they agitate the water and cause a circulation within the water. As the water is churned up by the propellers it comes in contact with the surface and therefore receives oxygen. The deeper ponds and lakes need a diffused aeration system as although fountains and propellers are efficient, they do not create a circulation large enough to include any water at lower depths. A diffusion system comprises three components, a diffuser, an air hose and a compressor. The compressor pushes air through the hose to the diffuser which is placed at the bottom of the pond and as the diffuser releases that air, it travels to the surface, aerating the water as it goes. Of course though, as the compressor needs a source of power, it must stay on dry land by the side of the pond and so you must ensure that you have enough air hose to connect the compressor to the diffuser.
