2 Types of Best Pond Aerators

There are two types of aerators, the bottom, and the surface aerators. The Surface aerators are the types that work from the top and it pushes oxygen downward so that it can be distributed all through the water.Surface aerators are excellent for ponds and don’t go deeper than 8 feet deep.

But when the pond is deeper than that, you may need a bottom aerator. It works the opposite way, that is, it pushes oxygen from the bottom to the top. The bottom aerator is best for ponds that are more than eight feet. Aeration is important for all kinds of ponds, regardless of the depth. You need to install one if you want your pond to be a healthy place for you and your fish.

Bottom aerators are usually complicated for anyone without technical knowledge about them. Before we proceed with the best pond aerator, let’s answer some common questions about fishing pond aerators.

Questions and answers about fishing pond aerators

When looking for pond aerators, most of the time you will end up with a lot of questions such as. How does it work? What is it going to do for my pond? How can I get the right size for my pond? What does the installation look like, can I do it myself? What about maintenance, is it hard to do? These are questions that may arise again and again. And for such an investment, you need to understand what you are going into. So, we will try to answer some of these questions before we introduce the best pond aerators to you.

Q: What does a pond aerator do?

Answer: Pond aerators increase the level of oxygen in the pond, which is necessary because it helps create a healthy environment for fish and other pond life. In general, the benefits of pond aeration include improvement of pond fish habitats, water quality, elimination of algae and phosphorus, removal of pond odors, breakdown of bacteria, taking care of mosquito problems.

Q: What is pond aeration?

Answer: This is a process in which oxygen is added to the water, which raises the level of dissolved oxygen effectively. This dissolved oxygen is what fish use to breathe, and other organisms use to keep the pond clean.

Q: Why do I have to aerate my pond?

Answer: Garden ponds contain many more oxygen consumers than natural lakes. Most of the oxygen that diffuses naturally into the pond is used by bacterial and chemical processes to keep the pond clean and balanced. Fish waste and other organic matter accumulate in the bottom and form a sludge layer.
The microorganisms at the bottom of the pond digest this organic matter and use the available oxygen. Also, plants and algae use oxygen at night. Koi, Goldfish, and other pond living creatures also consume oxygen. And without this artificial aeration, there would not be sufficient oxygen to meet the needs of all the aquatic life.

Q: How can I stop animals from chewing the power cord of my pond aerator?

Answer: You can use plastic-coated cables to reduce the possibility of animals chewing on power cords. If you are in a neighborhood that requires extra protection against animals and other damage, consider having your electrician installed the cable within a flexible PVC conduit.

Q: How can I prevent debris from clogging up my aerator?

Answer: Debris management in some ponds can be a constant maintenance problem. If the pond has an excess of vegetation, chemical methods or mechanical harvesting may be necessary for the aerator to function effectively.

In some cases, if the debris is garbage, organic matter or vegetation, then simply adding an intake screen will be enough. In most cases with smaller vegetation or string algae, adding a better screen material that can be installed outside of the intake screen can solve the problems.

Q: How do pond aerators work?

Pumping air to the bottom of the pond is the most effective way to aerate the pond. Aeration kits comprise of an air diffuser and air pump. The diffuser is positioned at the base of the pond. Compressed air is pumped from the air pump through an airline to the diffuser.

Air bubbles exit through the diffuser and goes up to the surface. The air bubbles at the bottom of the pond naturally rise towards the surface when they are released. While the air bubbles travel toward the surface, a little current begins to develop.

The current then pulls oxygen-depleted water from the bottom to oxygenate it and brings it to the surface. When the air bubbles get to the surface of the pond, it created a “boiling” motion. This motion revolves around the water and eradicates noxious gases such as hydrogen sulfide (the smell of rotten eggs) and carbon dioxide from the water.
