Should I Get an Aeration Device?

There’s a lot that goes into pond maintenance in Tucson, AZ. If you’re new to owning a pond, you might be wondering whether you need an aeration device. Although you don’t need one in general, if you’re going to stock your pond with fish or plants, it’s a good idea. Not only do fish need oxygen to survive, but it also helps sustain your tiny backyard ecosystem.

Here are the main reasons you should consider an aeration system:

  • Improves dissolved oxygen levels: Your pond has two different kinds of bacteria: “good” bacteria and “bad” bacteria. The good bacteria need oxygen to survive. If you don’t have an aeration system in your pond, your pond will fall into an anaerobic state. Anaerobic bacteria (meaning they don’t need oxygen to survive) are not efficient at breaking down organic matter in your pond. That means your pond may start to smell like rotten eggs, thanks to the excess carbon dioxide and hydrogen sulfide that anaerobic bacteria produce. Good bacteria break down organic material faster, and without the rotten egg smell—plus, it’s better for your fish and plants.
  • Upgrades your water quality: Murky ponds aren’t particularly attractive, but that’s what you’ll get when you lack an aerator. Organic matter and nutrients sink to the middle and bottom of the pond, which creates the murky look. An aerator will diminish the nutrients available, which keeps the pond water clear and discourages algae.
  • Reduces the possibility of “pond muck”: In addition to murky water, excess nutrients in the water create “pond muck.” This muck is not only gross when you step in it (if your pond is large enough for wading), but it can also be a breeding ground for leeches and other unwanted visitors. Get an aerator to reduce this risk and keep your pond looking (and feeling) great.
  • Decreases fish kill: Your fish need to get oxygen from the water, which you might know if you’ve ever owned an aquarium. It’s the same concept: an aerator helps deliver oxygen to your pond so your fish won’t suffocate. If you find that all your fish are dying at once, it’s likely due to a lack of oxygen.
  • Gets rid of the thermocline: Finally, using an aerator will get rid of the thermocline—the border between warmer surface water and colder deep water. Depending on how deep your pond is, this might not be a concern. The colder water at the bottom is oxygen starved, so an aerator helps move that to the top so it can receive oxygen. Meanwhile, the warmer oxygen-rich water sinks to the bottom, and the cycle continues.

As you can see, getting an aerator is in your best interest. Not only does it reduce unattractive murky water and pond muck, but if you have fish, it’s an absolute must. You can get aerators in a variety of types, including bubblers and fountains.
