When it comes to buying an aeration system for using in your pond, today there are several different types you can choose from, including even floating fountains. If they sound complicated, most aeration system providers will willingly also offer pond aeration support for whichever system you choose. A fountain is a popular choice of aeration system as it can also provide some character to your pond as well as being an effective aerator. As the fountain sucks up water to throw in the air where it can be aerated, it causes a circulation in the water ensuring that all the water is aerated regularly. If the water in a pond is not aerated it will become lifeless, unable to support fish life and encourage the growth of algae. As the algae will then start to take over the whole pond, the pond will become unsightly and smelly. Another popular aeration system is the propeller system which agitates the water allowing it to be aerated instead of throwing it into the air. Although, like the fountain, the propeller system also creates a circulation in the water, neither of the circulations created by either of these systems will have any effect on the water below a depth of 6 feet and so for ponds which are deeper than 6 feet, other aeration systems have to be used. The usual aeration system used for the deeper ponds is the diffused aeration system as this aerates the water from the bottom of the pond up.
The diffusion aeration system consists of 3 components, a compressor, a diffusion unit and an air hose. As the compressor is connected to a power source, it must stay out of the water at the pond’s edge but it is also connected to the diffusion unit which is located at the bottom of the pond, by the air hose. Once the compressor is switched on it will pump air through the hose to the diffusion unit and that then releases the air into the bottom of the pond. As the air released by the diffusion unit leaves the unit it starts to make contact with the deeper water allowing that to become aerated. As the air continues to rise to the surface it also aerates the water at shallower depths and so all the water, at all depths, is effectively aerated and remains healthy. Not all ponds of course are conveniently located next to a power source such as a mains supply but to combat that, some aeration systems now come with their own power source. Some of the aeration systems are provided with a windmill kit which, once set up, can provide sufficient power for the aeration system it came with. Other systems employ solar energy and so come with a solar energy kit which can be very efficient, some able to provide power for up to 3 days without seeing sunlight. Not only are these power sources convenient for ponds that are remote but, they can also be used by people that want to keep their electricity bills low.
