Ensuring Sufficient Pond Aeration – Pond & Lake Q & A

Pond & Lake Q & A

Q: How do I ensure my lake or pond gets sufficient aeration? – Jack of Maine

A: Take a deep breath. Living things, whether they’re above water or below, require oxygen to thrive. If your pond or lake houses fish, then the aquatic environment needs to be rich with oxygen, and the best way to do that is by aerating the water. Pond aeration is simply diffusing life-giving oxygen into water evenly throughout the water column using surface aerators or bottom-mounted diffusers.

To determine whether your pond or lake requires aeration, take your pond’s temperature. Measure the temperature of the water 1 foot below the pond’s surface, and do the same at the bottom of the pond. If the results differ more than 3 degrees Fahrenheit, then your pond is not sufficiently aerated and it may need a little help. For a simpler test, JUMP IN! If you’re warm above the waste and freezing at your toes, it’s a good sign your pond is not being circulated or aerated enough. Here are the most common ways to churn up the water:

Bottom Bubblers: Bottom-mounted air diffusers, like the Airmax Aeration System, are ideal for ponds and lakes deeper than 6 feet. They aerate ponds from bottom up, pushing air into the water via air stones or diffusers. These systems generally feature a shore-side cabinet that houses an air compressor, which is connected to diffusers at the bottom of the pond. The air is forced through the diffusers, which create medium-size bubbles that expand as they surface, releasing oxygen into the water and circulating the water column. These bottom bubblers are by far the most efficient at circulation and aeration.

Surface Aerators: Surface aerators, like fountains, provide pond aeration from the surface down. They agitate the surface of the pond, pulling water up from below and releasing into the air, where the droplets explode into a decorative spray pattern. The surface area on each droplet of water is saturated with oxygen, which it delivers back into the pond. Fountains pull water from about 6 feet down. For ponds and lakes 6 feet deep or less, a fountain can act as both a pond aerator and a decorative feature. Depending on your pond’s size, you may need more than one fountain to properly aerate. When ponds are deeper than 6 feet, fountains become more for decoration and you need to think about a bottom bubbler.

Alternative Aeration – Wind Power: If power isn’t available near your lake or pond, you can go with a wind aeration system to keep the air flowing. Windmills are primarily designed for decoration and they  come with one air stones to aerate up to 1 acre. You’ll need constant  wind blowing at least 3 to 5 miles per hour for continuous aeration, but they are a great backup system to an electric air compressor or in a remote location. Windmills are available in 12-foot, 16-foot and 20-foot towers. Remember: Windmills do not provide continuous aeration and should not be used as a direct substitute for electrical powered continuous aeration systems.

Alternative Aeration – Solar Power: Solar powered aeration systems are another great alternative to aerating your pond without having to pay for electricity. Solar aeration systems are great for both remote
installation and environmental conscience applications. They are for aquatic environments ranging in size from small decorative water gardens up to ponds or lake up to 5 acres. These fully automatic systems are designed to run up to 20 hours per day under standard operating conditions. The battery backup system allows them to run like normal under less than optimal conditions. One of the biggest downfalls of solar powered aeration systems are their high price tag.

POND TALK: What do you do to aerate your pond?

What Type of Aeration System Do I Need? – Pond & Lake Q & A

Q: I know I need aeration in my pond, but I’m not sure what type of aerator is right for me? - Several Customers

A: We all know why ponds need some type of aeration system (If your not sure why ponds need aeration, read the article Aeration in the Summer Heat), but there are many types of aerators on the market from Bottom Bubblers to Fountains to Windmills. The type of aerator needed for a pond depends on a few factors.

Picture of the Airmax Aeration System

Airmax Bottom Bubblers: An overwhelming majority of ponds fit into the category of Bottom Bubbler aeration. This system comes with a cabinet that sits on the shore. The cabinet houses an energy efficient air compressor. This compressor is then connected to a 4-stone diffuser plate(s) that sits on the bottom of the pond. This 4-stone diffuser creates medium sized bubbles that not only allow for adequate aeration, but also circulation. Many pond owners assume that since power is not located by the shore of their pond, that a Bottom Bubbler will not work. Just to clarify, a Bottom Bubbler can be placed up to 1,000 feet from the pond using direct burial airline.

designed, they will only pull water from about 6 feet down. When a pond is deeper than 6 feet it’s best to go with both a Fountain as well as a Bottom Bubbler to have adequate aeration. When the pond has a

depth of 6 feet or less then a fountain will act as both an aerator as well as a decorative piece. Please note: Depending on your pond’s size, you may need more than one Fountain to properly aerate.

Windmill: Windmills are primarily designed for decoration. If a pond is located where no power is available, then a windmill is really the only option to allow for some aeration. It is important to keep in mind that windmills only come with one stone and do not cover a large area. Also, they need constant wind

to have constant aeration. Windmills are available in 12′, 16′ and 20′ towers. Windmills do not provide continuous aeration and should not be used as a direct substitute for electrical powered continuous aeration systems.
