A pond is an attractive landscaping feature, but just like any other part of an intentional landscape, it needs care. If neglected, a pond can fill with algae, debris, and even garbage. Murky water and a bad odor can ruin the pond’s ambiance, not to mention the fact that stagnant water is a breeding ground for many insects. If cared for, though, a pond can be a thriving and balanced ecosystem. The key to caring for a pond is aeration.
Aerating a pond means increasing the level of oxygen in the water through one of several methods. In general, there are two main types of aeration systems, those that are below the surface of the pond and those that are above it. Below-surface aeration systems increase the oxygen saturation in the water by blowing out streams of air bubbles. The movement of the bubbles also helps to circulate and de-stratify layers of water in the pond. Aeration methods that work on or above the surface of the pond include floating aerators, which propel air downward; waterfalls; and pond fountains.
There are several reasons to consider pond fountain aeration. First of all, fountains aerate the pond as droplets of water from the fountain re-enter the pond. The tiny droplets have a large surface area for their size, which allows a large amount of oxygen transfer. In addition, a fountain helps to de-stratify the pond as it pulls water up into its pump. Keeping water circulating helps to cut down on excessive algae growth and insect populations. Mosquitoes in particular breed in stagnant ponds, and a fountain is one of the best ways to eliminate mosquitoes from a property. Finally, a pond fountain is beautiful to look at and listen to, and adding a fountain to a pond can increase the value of the property.
When choosing a pond fountain, it’s important to consider the surface area and depth of the pond. If the pond is small, a fountain may be able to provide sufficient aeration. However, a larger pond may need a sub-surface aeration system as well. In addition, the size of the pond determines the size of the motor required to pump the water into the fountain.
