Choosing the Right Fountain Aerator for your Lake

Choosing the Right Fountain Aerator for your Lake
If you wish to have a healthy lake or pond, a good aeration system is a must. Whether it be a fountain or sub-surface aerator, it’s important to maintain a system that is big enough to handle your lake or pond.

Types of Fountain Styles
No two fountains are the same and different manufacturers have different names for the fountains they make. Here are the top 4:

Geyser: A simple vertical pattern that shoots water straight into the air, the geyser is a common fountain style that helps with aeration.
Crown and Geyser: This pattern is a bit more complex. Several small geysers shoot from around a larger one to resemble a crown.

Cone: The water is forced to the edges of a disk like object in the nozzle and allows the water to create a cone like effect. Most effective fountain shape.  
Bubbler: The water in this design doesn't exactly shoot, but bubbles overs, to resemble an erupting volcano.
Once you select a pattern that works for you, you need to make sure you determine the water quality or other key features that need to be addressed. You can always contact our specialists to help determine the needs you have and how to solve them.


The 6’ Rule
If you have a pond or lake that is more than 6 feet deep, you’ll want to consider a sub-surface aeration system. A fountain aerator is only capable of aerating the water column, so anything under 6 feet deep will not receive proper aeration. You can still use a fountain feature, but we highly recommend you add a sub-surface aerator to subsidize the lack of aeration. 

Shape and Size Matter
Curves and bends can add dramatic features to your lake or pond, however, they can also restrict aeration. Ponds or lakes with irregular coastlines, islands, or coves can limit the reach of the oxygenated water and can be harmful to your pond or lake. We recommend that you aerate as much as possible to ensure algae and weed growth are kept at a minimum. Remember, you can’t over aerate a pond, but you can definitely under aerate. 

Other Considerations
The most effective fountain shape is the classic v-pattern (cone pattern). It does the job simply and effectively. Remember, the more decorative the spray pattern, the less effective it is at aerating because it uses more energy to create the pattern than to aerate your pond. Secondly, horsepower is very important. A good rule of thumb is to go with 1.5 HP per acre when using the v-pattern, if you plan to choose a more decorative  . If the fountain is for decoration more than aeration, 1 HP would be enough. Lastly, winterization is very important and is imperative if you live in an area that is prone to freezing. In order to save your equipment, you must remove any surface fountains, as the ice will freeze and can break your equipment. The exception would be out Scott Aerator Fountains; they can be left in during the winter but they shouldn’t be active. Here is a link to our Scott Aerator Fountains,  An active fountain in the winter can have a super cooling effect and can have a negative impact on the wildlife and equipment.
