Q: How do I know which aeration system is right for my pond?

Tim – Warren, OH

A: Yes, aeration systems can be confusing. If you’re not used to working with calculations that involve a lake’s surface area, depth and shape, deciding which system fits your fish pond can be a complicated matter.

Well get out your tape measure and calculator, because we’ve made the process easy. Here’s what you need to know to pick the right aeration system for your needs.

Pond Size

First, you’ll need to determine the size of your pond or lake so you can select a powerful enough aeration system to handle it. To calculate its surface area, measure the length and the width, multiply them, and then divide that number by 43,560. Each aeration system lists the pond surface area that it can handle on the package for easy selection.

Pond Depth

Once you know your pond or lake’s surface area, you then need to figure in its depth. It plays an important role in the system compressor’s efficiency and aeration area—the deeper the pond, the more area one diffuser can handle; the shallower the pond, the less area it can handle.

Look for the system that will handle the surface area at the depth of your pond. Ponds less than 6 feet deep will benefit from an efficient shallow water system, like the Airmax® Shallow Water Aeration System. It allows for multiple aeration plates that can be spread across the pond for more efficient aeration where the lack of depth reduces the area a diffuser can handle.

Pond Shape

Finally, take a look at your pond’s shape. If you have a round pond, it’s relatively easy to fit an aeration system, like the Airmax® Deep Water Aeration System, based simply on its size and depth. If you have a long, narrow pond or one with odd shapes or coves, however, you may require additional diffusers for optimum circulation.

Still having a problem figuring out the aeration puzzle? Let us help! We can look up your pond via satellite and size the aeration system for you along with a layout for diffuser placement. Just give us a call or shoot us an email!

1. my pond is approximately 1 and 3/4 acres. I want a fountain aerator
I need to know how much air line I need and what I need to hold it in
place as well as what size aerator I need to order

• Hi Gena – We would need a little more information from you to properly size and aeration system and/or fountain for your pond such as the pond depth and the shape. If you could please give us a call or send us an e-mail at Pondhelp@thepondguy.com we would be happy to assist you with an aeration layout.

2. Divide by 43,560??? Where does this come from?

• Hi Ranger Bill – This is to get the acreage of the pond. There are 43,560 square feet in an acre. So, a 3/4 acre pond has 32,760 square feet.
