Floating Pond Aerators

These aerators are designed to add aesthetic and offer aeration that is desired by most of the people. They take the water from the upper feet of the pond and throw it in the air, and then the oxygen is picked up. A cycle is formed, and the circulation returns the oxygenated water back to the pond. Basically, they are used for ponds that have shapes such as oval, triangular, square, or round. And the ponds which have irregular shapes can also benefit from these types of aerators. There may be a requirement for more units for achieving uniform aeration.

Submersed Aeration Systems

These systems are diffused in the bottom and help in releasing oxygen directly into the water. They work at precise locations inside the pond. Though, these aerators can supply oxygen to any pond but work amazingly for long, narrow, and kidney shaped water bodies. If the ponds have an irregular shape, then fountain aerators are not of much use as they are made to sit in center to cover more space.

Choosing a Perfect Pond Aerator

When you choose the best pond aerator, don’t be in a hurry. A few important things should be kept in mind and should be taken into account for the best aeration of the pool. For getting a perfect aerator the under-mentioned few points should be studied properly. This will help you in determining the best aeration system which is not only good but saves your future maintenance cost as well.

The Size Of The Pond

It is always said that the middle path or everything in moderation is the key to success. By this, here we mean that the oxygen should be provided in adequate amount by the aerator. Lack of oxygen is harmful and so is the excess amount. The size of the pond should be considered before you choose your piece of equipment.

The Depth Of The Pond

Like the size the pond depth should be known beforehand. As, deeper ponds require bottom diffusers and fountain pond air pump work best for shallow ponds. Knowing the depth of the pond holds much value before deciding to buy the best aerator. This way the oxygen will be made to mix properly in the water and will reach all dead spaces too.

The Shape Of The Pond

Before choosing an air pump system for your pond, knowing the pool shape is also vital. As we want all the parts of the pond should be oxygenated, so the shape has to be considered before investing. For the typical ponds (circles, rectangles, ovals, triangles), the standard aeration systems work great, and there are least chances of water stagnation. But if there is an irregular-shaped pond, then additional costs may cost you a bit more for overall aeration.

Summing Up

Select a good pond aerator which takes care of the water life efficiently and effectively. Not only the pond, but the surroundings will also breathe and feel fresh as a quality aerator will keep the pond in the best condition. Aquascape 75000 Pond Air 2 – Double Outlet Aeration Kit is one of our choicest aerators that performs and finishes its task wonderfully.

Aerator Power

After considering the above three factors, the power of the aerator should be weighted. The aerator you buy should have the ability to finish its requisite task. Some pond aerators can work well for both the small and large ponds, while the others may be fit for one type of pond. One should avoid the overworking of the machine and choose a product which is the best alternative for the pond.

Benefits Of Using Aerators

For supporting the aquatic life, the ponds need to be aerated, and the oxygen levels of water should be raised. Then using a pond aerator is the best solution. The fountain aerators are a good option for symmetrical and small or medium-sized ponds, while the Koi needs much oxygen to thrive and survive, so an oxygenator with more power is required for the same.

The little flow of water has to be increased in the pond for much-needed reasons. Even the ponds without fish require proper aeration in the long run.

Let us take a quick view of the advantages of aeration

Increases Oxygen Levels

On the other hand, the aerobic bacteria feed on organic materials and emit gas which is odorless. This will certainly keep the pond fresh and nice.

The basic motive is to increase the oxygen levels in the pond water, and the fish, plants, and good bacteria tend to thrive and live more comfortably.Without proper oxygenation, the pond life would have become hell and it would stink badly due to the multiplying anaerobic bacteria. These types of bad bacteria emit bad odors, generate hydrogen sulphide and carbon dioxide, after consuming organic material.

The Depth Of The Pond

Like the size the pond depth should be known beforehand. As, deeper ponds require bottom diffusers and fountain pond air pump work best for shallow ponds. Knowing the depth of the pond holds much value before deciding to buy the best aerator. This way the oxygen will be made to mix properly in the water and will reach all dead spaces too.

Less Mess

The older ponds with time may get a build-up of more nutrients, especially on the pool bottom. This turns into filth and muck, and there could be leeches and foul smell. If ever you get a chance, you would never step up on such kind of muck.Getting rid or preventing the build-up of such kind of grime or debris, the more oxygen needs to be circulated throughout the water.Aeration lets the good aerobic bacteria to form their colonies in the water that eat nutrients and result in less build-up of debris.

Improves Water Quality

The water surface of the pond also appears on foggy and dirty if the debris tends to settle with time. The water flow and oxygen levels are improved by using a good aerator and in turn this improves the water quality of the pond.Ponds weed and algae remain in control if the nutrients they consume aren’t enough after aeration.

Gets Rid of Thermocline

The deep bottom of the pond is colder than the upper surface which is warm. Placing an aerator makes the water mix with both the layers (upper and lower), so that proper oxygenation is done everywhere. The temperature balance will also take place this way in the pond. With movement a lot of good bacteria will travel deep down to the pool bottom.

Reduces Fish Dying

When the levels of oxygen drop in the pond, the fish tend to die often. In case the outside temperatures are cold the decomposition of organic materials emits gases and which tend to get trapped if the pond freezes. This will leave the fish with lesser oxygen and resultingly the fish might suffocate.

Frequently Asked Question's

Q1. Which one is better, a submersible, or a fountain aerator?

Ans 1.If you are buying an aerator for a shallow pond, then the fountain or the surface aerator is a perfect option to go for, while the submersible aerators tend to release oxygen from below the water surface. The submersible ones are great for deeper ponds. It completely depends on the type of pond you have.

Q2. Should I switch off the pond aerator if pool algae develop?

Ans 2.The aerators control and prevent the growth of pool algae, so switching them off should not be the case if the pond develops algae. Turn on the aerator for proper oxygenation.

Q3. How to prevent the floating of the pond aerator line?

Ans 3.When you buy a pond aerator, most of them come with a weighted airline, which helps them to sink. Go for a product that has this quality, and the fishing line weights can be used to force the line to sink. It is recommended to replace the product, which is without a weighted airline.

Q4. Should the pond aerator be made to run 24 hours a day?

Ans 4.It is not essential to run the aerators for 24 hours every day. During the daytime, oxygen is produced by the algae through the process of photosynthesis, while the reverse happens at night, as respiration causes the oxygen levels to fall in the water.
