What types of aerator for ponds and reservoirs? Recommendations for making devices with your own hands - Overview + Video The popularity of artificial ponds has never faded. Now such reservoirs have reached a new level, they can be found in many private estates. Sizes can be very diverse, depending on the purpose of their creation. For the normal functioning of reservoirs, you need to take care of creating an aerator for a pond with your own hands, which is quite possible, so as not to spend money on ready-made models.

What are aerators for?

First of all, they provide purification and simultaneous saturation of water with oxygen, and this, in turn, prevents water stagnation.

In addition, without purification, the water will bloom, and the smell from it will become unbearable.

General information

Factors indicating the need to install an aerator

  • What types of aerator for ponds and reservoirs? Recommendations for making devices with your own hands - Overview + Video Fluctuations in temperature . Such processes occur every day, since day changes to night, and one season passes into the next. Warm water improves the metabolism of fauna and flora, which provokes an increase in the need for additional oxygen.
  • The formation of large amounts of sludge , which interferes with the normal metabolism in the water.

  • Large number of plants .
  • Excessive fauna . With the active reproduction of fish, the need for oxygen increases.
  • There is not enough natural mutual aid . The viability of any water body with living creatures is directly related to weather conditions.

    During drought, water evaporates, and with it the necessary trace elements. In addition, rainwater fills the ponds with water. Without movement, layers of warm and cold water stagnate in the reservoir, which also negatively affects the microclimate.

Aerators for ponds and reservoirs are compression-type installations, the main task of which is to mix water with oxygen. Such units have a second name - air compressors.

In natural reservoirs, this process occurs by itself, since air constantly penetrates into the water as a result of mixing water flows: rivers flow into the seas, waters are filled with atmospheric precipitation, strong winds blow, filling occurs through underground springs with natural trace elements. Accordingly, such interchanges do not take place in artificially created ponds, so they must be created with your own hands.

Home ponds have their own ecosystem, which functions in a different way. This is due to the fact that when creating a pond or lake, the bottom is lined with waterproofing material, which becomes an obstacle to the penetration of oxygen from the soil. The surface area of ​​artificial reservoirs is often small, and they are located mainly surrounded by trees, in this regard, neither the air currents carried by the winds, nor atmospheric precipitation can fully saturate the water with everything necessary.

Lack of oxygen in the water leads to the death of plankton, fish, snails, frogs and other living creatures.As a result, silt, rot, bottom sediments appear in the water, and only a swamp remains from a beautiful reservoir.


A lack of oxygen in the reservoir is indicated by the formation of a film on the water, fish often appear on the surface of the water, snails rise from the bottom, and silt appears.

Types of aerators for the pond

The aerators are divided into two groups:

  1. Stationary - capital-type units of the installation, which are intended for installation in a particular pond and carry out their work on an ongoing basis in a given mode.

  2. Mobile devices are intended for seasonal use, their capacity is enough to fully service several ponds. Aerators of this type are best suited for small reservoirs or for those that do not need constant oxygen filling.

Classification of aerators for a pond

By type and place of installation, as well as features of work, it is carried out into several types.

Outdoor aerators compressors for ponds . These installations look like small fountains or waterfalls.

Often used for installation in home ponds to add an attractive appearance. An important point of such units is that not all inhabitants of the pond will appreciate the sound of falling water. The peculiarities of the work of external aerators are that the pump draws in water from the pond, and the subsequent discharge in the opposite direction. When a stream of water is in the air, oxygen saturation occurs.

The principle of operation of these units is similar to the features of outdoor compressors, with the difference that water is not sucked from the pond. The process of saturating water with oxygen is carried out by blades, which are driven by a motor. The blades beat the water with a certain force, stirring it and saturating it with air. Please note that these installations also make a lot of noise.

Pond Bottom Aerator .

It is a new pond device that has earned the reputation of being the most efficient to date. The compressor that makes noise is installed on the shore of the reservoir, and a tube with a diffuser is lowered into the water. Oxygen enters through small holes, passing through layers of water. The result of this work of the installation is the saturation of the pond with oxygen and mixing of all layers of water. This aerator features quiet operation.

Combined aerator. The principle of operation of the unit is based on the operation of a pump or compressor. The compression unit is installed on the shore of the reservoir, and the diffuser is mounted in the water. The head of the diffuser remains above the surface of the water, and air is saturated by the flow of water, which beats with a fountain.

Pond wind aerator .

This installation differs from all other types of aerators in autonomous operation.The unit is driven by wind force. The design is mobile and stationary, it is created from large-sized blades located on the water surface, as well as a propeller submerged in water. The principle of operation is as follows: the wind drives the blades, they use the propeller stroke, which mix the water and a seething is formed.


Wind-type aerators are most often used in the country, as well as in those areas that remain without the participation of people for a long time. The installation is capable of operating all year round without adjusting the process by the owner of the reservoir.

We create an aerator for a pond with our own hands

It will not be difficult to make an aerator for a pond yourself. The main thing is to study the assembly instructions, and also stock up on the necessary materials. The cost of ready-made installations is not small, but if you make it yourself, you can save a lot of money.

For small ponds, it is enough to use an aerator of a simple design, which can be assembled from materials that the summer resident always has at hand.

Assembly of the ejector aerator


  • drainage pump with low power;
  • a piece of sewer pipe with a section of 32 mm and a length of 2 m;
  • a branch pipe with a length of 40 cm and a section of 32 mm;
  • an angled tee 45 °;
  • cable in double braiding.


The importance of choosing a tee with an angle of 45 ° is explained by the fact that when the pipe is connected at an angle of 90 °, there will be a constant flow of water into the unit.

Assembly process:

  • The sewer tee is attached to the drain pump using a fitting for connecting the hoses of the aerator for the pond.

    To ensure a secure connection, a silicone-based sealant is used.

  • On the reverse side, a branch pipe is inserted into the tee, the length of which should be less.
  • Insert an angle of 45 ° into the upper branch, then fix a two-meter pipe.
  • An electric cable is connected to the aerator. The wire must be sealed with electrical tape, which is wound in several layers, and then placed in a corrugation.

  • The pump is placed at a depth of 70-100 cm of the water surface, and the water intake pipe should be on the water surface. In order for you to succeed, make a kind of mast from a steel pipe and fix it at the bottom of the reservoir.
  • At the last stage, an aerator is attached to the mast and an electric current is supplied.

Assembling the bottom aerator

The cost of assembling an aerator of this type with your own hands is small. To do this, you will need to find a compressor from a car with a receiver.


  • Compressor ;
  • High pressure supply hose;
  • Clamp;
  • Tees ;
  • Nozzles, spray.


The nozzle can be made from a plastic bottle by first making a hole in it.To reduce the size of air bubbles, the bottle is wrapped in low-thickness foam rubber.

Assembly process:

  • The compressor is placed near a reservoir or hidden in a nearby annex.

  • The central hose is connected to the compressor and pulled to the pond.
  • With the help of tees, bends are made depending on the number of nozzles. Staples are used for secure fixation.
  • Diffusers are attached to tees and placed at the bottom of the reservoir. To prevent them from rising to the surface, you can put heavy stones on them or fix them at the bottom with pins with curved ends.


The pond bottom aerators cannot operate continuously and the unit emits an annoying loud noise. Devices of this type are used to periodically saturate the water in ponds with oxygen.

DIY assembly of a pond wind aerator in winter

This type of installation is best suited for operation in the winter season. It is not difficult to assemble it, you will need the most common parts that can be found on the farm.


  • What types of aerator for ponds and reservoirs? Recommendations for making devices with your own hands - Overview + Video A piece of square metal measuring 30 x 30 cm.
  • Steel rod with a diameter of 20 mm.
  • Sealed bearings that must match the section of the rod.
  • Metal strips with a thickness of 2 mm, and the length should be slightly larger than the bearing size.
  • Plastic barrel.

  • Cooling fan.
  • Fasteners.

Assembly process:

  • Cut eight pieces of squares out of metal and connect them into cubes. A cross member is installed inside each of them, in which a hole is cut and a bearing is inserted. Bearing centers must be in line.

  • The steel bar is placed in the bearings.
  • The plastic barrel is cut into two parts and the blades for the wind turbine are obtained.
  • Using metal hinges, the blades are fixed at the top of the rod.
  • At the bottom of the steel bar, blades are attached, which, as a result, will be located above the surface of the water.
  • The assembly of the mast for the wind-type aerator is carried out at the last stage and after that it is installed in the reservoir.

A floating wind aerator for a pond is created using plastic barrels, bottles or foam fixed to the mast.
