If you have a pond on your land and you want to keep that pond healthy, capable of sustaining fish and not becoming a smelly eyesore, you will have to use an aeration system. Fortunately pond aeration2015 is not difficult as there is now a wide variety of different aeration systems from which you can chose but be careful to use one that is appropriate for the depth of your pond.
The use of fountains as an aeration system are a popular choice as, as well as serving to aerate the water, they can also add character and beauty to a pond, enhancing the overall look of any garden. Unfortunately though, fountains are only effective aerators for shallower ponds. Another popular aeration system for shallower ponds is the propeller system. This system has a propeller turning in the water agitating that water allowing more of it to interact with the surface where is can absorb oxygen from the air. Regardless of the size of the fountain or propeller, neither of these systems though is effective for ponds with a depth which is more than 7 feet as their actions will not unsettle the deeper water which is most in need of oxygenating. For these deeper ponds, a diffusion system of aeration is required.
A diffusion aeration system contains three main items, a compressor that can pump air, a diffuser which can allow the air to be released and an air hose to join the two. The diffuser will be located at the bottom of the pond where it can release the air pumped to it by the compressor which is located on land close to the pond. As the air is released by the diffuser, not only does it aerate water on its way to the surface but it also creates circulation within the water, bringing the deeper water to the top and the shallower water to the bottom and this continuous circulation ensures that all the water in the pond is fully oxygenated and healthy enough to sustain fish life and deter the growth of smelly algae. Obviously with a diffusion system of aeration, the compressor will need a source of power and although many of them generally are powered by electric current provided by an outlet to the house’s mains, for those ponds that are more remote, there are today alternatives that can be used. One alternative is to use the age old power of a windmill, the windmill, as the blades turn, allows the diaphragm of the compressor to move up and down pushing air through the hose to the diffuser. Another alternative is more modern as it requires the use of solar power.
Some of the compressors available in diffusion kits today, are specifically designed for use with solar power and this can in the long term, also be cost effective as there is no current to be paid for on your electricity bill however, they will need extra attention for installation which could mean an extra initial cost.
