When considering an aeration system to use in your pond, you should always take into consideration the depth of the pond to be aerated. Shallow aeration systems are considered suitable or ponds with depths of no more than 6 feet whilst deeper ponds need a diffused aeration system. A diffused aeration system has three main parts and these pond aerator parts are a compressor, a diffuser and a length of air hose that will be used to link the other two parts. As it is the compressor that will be also connected to a power source, it has to remain on dry land next to the pond whilst the diffuser is placed at the bottom of the pond. The length of the air hose needed will therefore depend on the distance there is between the compressor and the diffuser. Air that has been pushed from the compressor to the diffuser is released into the bottom of the pond where it can oxygenate the water on its way to the surface, oxygenating all the water in the pond. As this type of system oxygenates the water from the bottom up, it is considered to be the best system to use on deeper ponds or even lakes. Two of the most popular shallow pond aeration systems are the fountain and the propeller systems. A fountain is more than just a show piece as, when it throws water into the air, that water has the opportunity to be aerated as it passes through the air. As the fountain also causes the water in the pond to circulate, all the water in the pond can be successfully oxygenated. The propeller system consists of propellers spinning at the surface of the water which agitates and moves around the water allowing all the water to come in contact with the air and be oxygenated.
It not only the diffused aeration system which needs a power source as the fountain and the propellers do also. For this reason and because sometimes ponds are located far away from the contemporary power sources, manufacturers include in some of their aeration systems, an independent power source, especially designed to provide sufficient power to operate that particular system effectively. One of these power sources is a windmill which of course has been providing power for many years and has just been adapted in order to provide sufficient power to an aeration system. The other source of independent power is solar energy. Only now becoming popular as a free, renewable energy source, solar power is perhaps the ideal answer for aeration systems that are located in somewhat remote places. Not only can all of these solar power systems provide sufficient energy to power the aeration systems they were built for but, some of them can even provide power for the aeration system for up to 3 days without being recharged by sunlight.
If a pond owner does not use one of these aeration systems, their ponds will soon become over run by algae which are unsightly and often smelly.
