You are in the park walking past a pond when you notice the fountain in the center of the water. You admire the water being thrown into the sky in an appealing shape. But, little did you know, that fountain wasn’t just there for looks. Surface fountains are one form of water aeration that prevents algae and unhealthy water. This oxygenation process comes in many forms, so does the shape of the fountain really matter?
There are a few things you need to consider when finding the right shape fountain for a particular location and pond. Factors that must be determined are the, height, shape, position, and lighting.
Too Tall or Too Short?
Determining the height of a spray has several factors. The height of the spray should not be more than half the length of the pond. If a spray is too high, the water is more likely to be blown out of the pond on a windy day. This could cause drastic water level changes in a pond and threaten the environment.
Not only is pond size important, but also environment. Keeping in mind where the pond is located and what the surrounds are will give you a better understanding of the height needed.
For instance, if the pond is in the middle of a large business building complex will tall buildings, a taller fountain would be a good choice. Assuming the pond is large enough, the taller fountain would match the tall and powerful image of the larger buildings. On the other hand, a small pond in a homeowner’s backyard would call for a smaller or wider fountain.
Determining the height of the spray will then help you identify the needed motor and model. Once the necessary height is chosen, a shape to match must be found.
Shapes on Shapes on Shapes.
There are many shapes to pick from for surface aeration fountains. Knowing the height of the spray will help you narrow the shape options. Bends and curves add a dramatic look to ponds, but they also restrict circulation. The more aesthetically pleasing shapes are still operational for smaller, shallow ponds but not for larger, deeper ponds. Sunburst, Phoenix and Rocket are three common fountain shapes for ponds.
The Phoenix’s two tiered pattern combines aesthetics with aeration, and is popular in commercial and residential settings alike.
All three patterns operate in shallow waters of 30 inches or less. To view more fountain shapes click here. The position of the fountain needs to be considered to ensure proper aeration.
A Little to the Left, Now Back Some to the Right.
Positioning of a surface aerating fountain plays a role in the effectiveness of oxygenation. Oxygenated water created by the fountain may not reach isolated sections of a pond. In ponds with an island, cove, or irregular shorelines, multiple or larger fountains may be needed. Incorporating a surface fountain with several sub surface systems in hard to reach areas will create better aeration. You cannot over aerate a pond, but you can under aerate it. Keeping in mind the length of the power cord in relation to the power source will also play a role in the location of the fountain.
Light It Up!
Adding lights to fountains creates a great look. Although lights are not necessary, many parks and business add them for the aesthetic feel. Some studies have shown that colored lighting such as blue and pink have calming affects on people. Often times fountain colors are placed on a looped color change timer.

Now, next time you see a fountain you will not just see and pretty shape or color, but a whole story. Make these considerations in your next fountain installation or purchase.
