Choosing the right lake fountain pump and aeration system is essential for your property. You will want to find the best combination of cost, energy efficiency, and flow rate for your property.

Fountains typically have a large pump that floats on top of the water. They spray water streams into the air, creating surface agitation and folding oxygen into the water.

Cost

A Fountain can be a very attractive addition to a pond or lake, providing a dramatic display and a soothing sound. However, they are only the optimal choice for some water features.

A sub-surface aeration system is much quieter and less conspicuous than a fountain. These systems work best in ponds and lakes that are 6 feet deep or smaller and are designed to release oxygen into the water column at precise locations.

They also can be used in deeper ponds to increase oxygen levels in those areas that do not have good oxygen availability. Increasing oxygen in these areas can greatly benefit aerobic bacteria, which helps to clean up organic matter from the pond.

The cost of a properly sized fountain pump can make the difference between having an excellent aeration system and not having one. The chart below will help you choose the right pump size for your pond or lake. The higher the horsepower, the better the aeration you will get.

Energy Efficiency

Choosing the right lake fountain pump and aeration system for your property is essential to maintaining healthy ponds and lakes. These systems will help keep your pond clear and odorless while helping to aerate the water for optimal oxygenation levels.

The energy your lake fountain pump and aeration system will consume depends on a few things. First, what is the static head height of your pond?

A pond that is a few feet high and wide will only require a low to medium-head pump. On the other hand, a waterfall 10 ft high or more will need a medium to high head pond pump to move that much water.

Most ponds need a sub-surface aeration system to aerate the entire pond properly. These systems use a compressor onshore and deliver air through an air hose to a diffuser at the pond’s bottom. The air bubbles rise to the surface, aerate and mix with the pond water.

Flow Rate

The flow rate is one of the most important aspects when choosing a lake fountain pump and aeration system. The flow of water in your pond or lake will impact some things, from how fast it cleans the water to how much time biological filters and UV clarifiers have to work.

Flow rate can be calculated in many ways. The most common is to measure how long it takes to fill a container and divide that number by six (or gallons per minute).

Once you know your desired flow rate, determine a pump’s head height. Manufacturers often list their flow rates at several head heights, so you can compare how strong a pump is.

Maintenance

One of the most important and effective ways to keep your pond or lake water clean and healthy is by circulating it. Floating fountains and aerators are excellent options for adding oxygen to your water while also helping to reduce the amount of algae and muck in your pond.

In addition to the aeration benefits, these systems can add an aesthetic element to your property. Aerators are often paired with fountains to create a dynamic display in your lake or pond.

To ensure your aerator performs at its peak, it should be serviced regularly. Depending on the intensity of use, this can include replacing seals and piston rings.
