Adding aeration can be a necessary project and many golf managers and supers like to go through the process of learning how to build their own aeration system so they can reduce costs and maintain control over the system. Whether you want to have a do it yourself style aireator or prefer a pre-built, turnkey system is up to you. It depends on how much time you have to spare and what your budget is!
Simply put, adding aeration to a pond, water-garden or even a natural lake is one of the best methods to control algae and maintain clear waters and discourage the buildup of bottom sediments.. It is extremely important never to overlook aeration when building a new golf course pond or when trying to restore one that is undergoing eutrophication especially in small basins that have a large organic load and that are typically mucky at the bottom. The organic material can be grass clippings, so it is best to leave a perimeter of natural thick vegetation and even aquatic plants to help reduce erosion and prevent runoff laced with fertilizers from getting into the water.
Our experience has shown that in most cases that adding air diffusion into the bottom levels of the golf course pond is often the the best form of aeration. This manner of aerating is basically the injection of air bubbles into the water to supply oxygen as well to create water movement because as the small air bubbles rise to the surface they create a movement that pulls oxygen deprived waters from the depths up towards the surface where they can interact with the atmosphere and achieve a high level of efficient oxygen transfer.
The water of the golf course pond is continuously being turned over and circulated towards the the surface by air diffuser plates, airstones, disc diffusers, or coarse bubble homemade diffusers that some people build themselves. There are many ways to get the air into the golf course pond but the general rule is that the smaller the bubble the better the efficiency of the system will be. Aeration can be done with electric air compressors or linear pumps or by windmills or even solar aeration systems! There are many ways to achieve the goal and the location of your golf course pond will determine whether you want to use a windmill for aeration, an electrical system, or a solar pump.
Whatever way you do it, take the time to install the best system you can afford as seeing a golf course pond with clear water and happy fish and frogs is truly a joy and any fish lover knows that maintaining fish, either trout, ass or koi, is a passion and now to be taken lightly!
Aeration, depending on your longitude and latitude in the world can be effective all year round or only during certain seasons but it is undoubtedly the key ingredient in maintaining a healthy aquatic system. The benefits of using an aeration system, especially when combined with applications of natural golf course pond bacteria that feeds on organic materials like leaves and fish waste, will return your golf course pond to vibrant health in no time at all!.
Building an aeration system can be a snap especially if you have a golf course pond store in your town where experts can help choose the best system components for you, although looking on the Internet for golf course pond supplies is another fast way to get the information you need. But be careful, there are many people trying to get golf course pond owners to part with their hard earned money with new fangled technologies like ultrasonic algae killers or complicated bubbler systems, when the fact is it is not rocket science!
The heart of any lake-bed, or bottom-mounted aeration system is often the air compressor itself. There are a variety of compressors that are quiet, small, energy efficient compressors that will pump a steady and constant flow of oxygen to your bottom-mounted diffuser system. The depth of the golf course pond where the diffusers are located will determine the type of compressor you require. Shallow golf ponds less than 9 feet deep can often be aerated with a small linear or diaphragm type of pump that are usually fairly silent and real energy misers! If you have a deeper pond, from 8 to 15 feet deep you may need to use a rotary vane compressor, although the carbon vanes are known to require changing every 18 to 34 months. Piston compressors can delivery up to 35 psi or more and are excellent for deep water aeration. While piston compressors often do not have the high levels of CFM (cubic feet per minute) of airflow as a rotary vane or linear pump, they make up for it in reliable strong airflow.
Windmills can also be used and in North America there are a few choices of windmill aeration systems both in Canada and here in the United States and we have even seen some real go-getters build a windmill aerator out of old cars and tractor parts, but we wouldn't recommend it. The standard windmill like a Superior Windmill or Koenders Windmill or Beckermills Windmill or American Eagle Windmill or Outdoor Water Solutions Windmill works by having a diaphragm compressor in the head of the windmill. As wind turns the fans of the windmill compressed air is forced down the airline into the airstone in the pond. No electricity is required and the simple technology has worked extremely well for decades as farmers across the plains have attested to. Aerating dugouts with a windmill is a popular practice in areas where there is often no electrical source, plus there is only the initial cost and construction of the system to contend with and no ongoing maintenance fees.
