How much should the air pump work in the aquarium

The principle of operation of the aquarium water pump is very simple. Through the tube enters the air air, the pressure of which is regulated by means of clamps and valves. Absolutely different parts of the water pump are responsible for the bubbles. These are sprayers attached to the airway tubes.

They create small bubbles, which are also decorative decoration, especially in combination with the backlight, as seen in the photo. Sprayers are located at the bottom. Each rising bubble mixes the water, equalizing its temperature. In addition, the bacterial and dust film on the surface is destroyed.


According to one of the classifications, the water pump for fish can be unregulated and adjustable. In the latter case, the front or side panel of the device has a special regulator. By rotating it, you can affect the performance of the water pump, thereby changing the number of bubbles. This increases or decreases the intensity of aeration. An adjustable air pump can have different types of regulation:

  1. Electronic. It limits the course of the membranes. The disadvantage is that the electronic part is exposed to heat.
  2. Mechanical. The vibrations of the membranes are limited by the feet, or the magnets are moved away from the coil inside the air pump for the aquarium itself.
  3. Overlapping output channel. More common option. In this case, close the valve located at the transition from the duct to the sprayer.


The unregulated water pump is simpler in the device. It has no additional parts that would affect the power of the device and aeration. Performance remains constant, so power consumption rises. In addition, the noise from such a water pump for the aquarium can not be reduced by reducing its power.

How Much Should The Air Pump Work In The Aquarium

If the aquarium is populated with fish and plants in a small amount, then the time of the water pump can be determined independently. It is not necessary to keep the equipment on all the time. Watch the behavior of the fish. If they start to get enough air, especially from the surface, then immediately turn on the water pump.

The principle of operation is as simple as the device device. Pumps for aquariums are equipped with special tubes through which air enters the tank. The oxygen supply is regulated by means of valves. At the end of the tubes are sprayers that emit air bubbles. They are made of abrasive substance. Sometimes they include a grinding stone.

Air bubbles are created using sprays. They are located at the bottom of the aquarium. During aeration, all layers of fluid in the tanks are mixed, and therefore the temperature becomes homogeneous. This process helps to eliminate the dust film located on the surface.

There are special water pumps that simultaneously have a filter – pump for the aquarium. We talk more about them in another article.

Water pumps may differ by the presence of a special regulator. He is responsible for managing the performance of the machine and adjusting the flow of bubbles in the aquarium. The water pump is equipped with a special device, thanks to which the adjustment is made. There are several types of regulation:

  • The mechanical type of regulation is based on the action of the legs or magnets. And their use regulates the oscillation of the membranes.
  • Electronic type limits membrane travel. Among the disadvantages of a high degree of heating element.
  • One of the common types is valve overlap. It is located on the tube, between the air duct and the sprayer. To adjust the air supply to the tank is required to overlap the element.

An unregulated water pump is not equipped with additional elements that regulate it. The device device is simple, but the performance remains unchanged. The disadvantage is the constant noise, which cannot be adjusted by reducing the power of the water pump. It consumes a lot of electricity.

By type of device emit:

The first look is more durable. The principle of its operation is based on the reciprocating movement of the piston, which pushes the air out. The water pump emits little noise, which is a plus of this model. It is well suited for aquariums located in bedrooms or children’s rooms. The model can be installed in tanks with a large volume, as it has a good capacity.

The diaphragm water pump is simpler to install. The principle of its work is different from the first type. This device passes the air flow from the chamber, which is connected to the membrane. Due to the magnet oscillations, a pressure drop is achieved, which leads to the process of supplying oxygen to the reservoir.

You can purchase aerators of two types. It is recommended to install the diaphragm pump in the aquarium during daylight hours. It is possible to attach it to several small aquariums at once. The second type is set at night.

There are aerators that are powered by alkaline batteries. They are thin and make a lot of noise when working. Action time is about 5 hours. Used when moving or lack of access to electricity.

The performance of the water pump plays an important role in the selection. It may depend on the population of the reservoir, as well as its volume. Under the performance refers to the amount of air that surpasses the aerator for a certain period of time. It is calculated by the value, which is 0.5–0.8 l / h per liter of liquid in the tank.

When choosing an aerator, the height of the aquarium is taken into account. The larger it is, the more powerful the apparatus must be, since the incoming air overcomes the pressure of water. Have a role on the power device holes in the sprayer. If they are small, the aerator will need more power to supply oxygen.

Working time depends on the population of the aquarium. Small tanks with a low content of plants and fish do not require round-the-clock aeration.

Work can be adjusted independently. This requires watching the behavior of the inhabitants. If the fish rise to the surface, it is necessary to turn on the device or increase the oxygen supply.

At night, the water pump must work. There are representatives who are nocturnal. Due to the lack of light, plants begin to emit carbon dioxide. Lack of oxygen will lead to the death of the inhabitants of the reservoir.

It is impossible to keep the device permanently on, as the vibration adversely affects the condition of the inhabitants. The exceptions are some species of fish that need round-the-clock aeration.

Each aquarist uses a water pump individually because there are personal requirements for a separate tank.

Aeration of water in the aquarium

Aquarium intake pumps are 2 types: piston and diaphragm. If the goal is to purchase a device that will emit a minimum level of noise, you should choose a water piston pump. When there is a need for several devices for aeration of air, you can use two at once: piston and membrane.

To save energy, you can choose a membrane vodushny pump. Its connection is possible at once to several aquariums. A serious disadvantage of this type of device is strong noise. The fact is that the principle of operation of the pump is based on vibration. If the aerator is designed for operation in water (submersible), then the noise produced by it will be less. However, such devices are not very common. One of the options for dealing with noise is to install an aquarium in a separate room where no one sleeps.

Due to poor performance, such devices are not recommended for installation in aquariums with a volume of more than 150 liters. Piston water pumps operate as a result of the movement of the piston, which generates air flow. This type of equipment is characterized by higher productivity and a long service life.

First of all, it is necessary to clarify that in relation to aquarium aerators the concept of "silent" is not entirely correct. It is more correct to call them quiet, because the device still produces some noise during operation. When choosing a water pump for a small aquarium, you should look at the model JBL ProSilent a100, which is equipped with a built-in silencer. This device is of the membrane type and includes a spray gun, a 2 m tube and a check valve.

In addition to the aerator, the manufacturer also offers connecting hoses and nozzles. water pumps for the aquarium how to choose, decide only the owner. If it was not possible for some reason to purchase the device, you can make it yourself from almost any available means.

Fish breathe oxygen and exhale carbon dioxide, which plants consume during the day of photosynthesis, releasing oxygen. Plants play a major role in maintaining the required amount of oxygen. Different plants supply different amounts of oxygen. If the ratio of plants and fish in the aquarium is chosen correctly, then both gases are sufficient for them, and they feel great.

Aeration performs the following tasks:

  • Saturates water with oxygen.
  • Creates a circulation of water in the aquarium.
  • It equalizes the temperature in the whole aquarium.
  • Destroys the bacterial and dust film formed on the surface of the water.
  • Simulates the necessary environmental conditions, such as flow. These conditions are necessary for some species of fish.

But if you have a lot of plants in the aquarium, you can not use aeration. aeration is used to remove excess carbon dioxide. Our industry produces various types of micro water pumps powered by AC power. The drive in them is an electromagnet, which informs the lever connected to the rubber membrane, 50 reciprocating movements per second. They provide performance up to 100 liters per hour.

aquarium aeration

When you turn off the pump, water can rise through the hose and, if the pump is installed below the water level in the aquarium, then, according to the principle of communicating vessels, it enters the pump and spills onto the floor of the room. Vibro water pumps need additional inventory, such as a hose and a suction cup, and clamps to adjust the air supply.

Foreign companies produce various air pumps with a capacity of 1 to 100 liters per minute. But you should not choose too powerful water pump for your aquarium, because it can cause stress to the fish. The volume of the aquarium that this or that water pump is designed for is usually indicated on the package.

Many models are equipped with a built-in filter. Such water pumps are very convenient. The air in these water pumps is mixed with a water jet directed back to the aquarium, this creates additional airing. They are installed directly in the aquarium. Filtering materials from such filters are quickly contaminated and they need to wash the filtering media once a week.

How to choose an aerator?

Quite a common question among beginners, and experienced aquarists – how to choose an air pump for an aquarium? And this is not surprising, because the variety of devices will make you think, and sometimes even lead to a dead end. We have already found out why an aerator in an artificial reservoir is needed. However, oxygenation is not the only purpose of such a device.

It is necessary to take into account such a moment as the possibility of mounting the device, because not all water bodies can be equipped with a filter, for example, in mini-aquariums or spawners. In addition, the water pump, in contrast to the filter, is a mobile device. This suggests that the pump can be installed in any convenient place, or even moved to another room if noise interferes. Separately, it should be said about the autonomous water pumps that run on batteries or batteries.

In addition, they can be used when transporting fish, because, depending on the distance of the trip, aquatic inhabitants can simply suffocate without oxygen. Despite the low cost, the device is very useful. In such pumps, you only need to change the batteries as needed or recharge the batteries in a timely manner.

How Much Should The Air Pump Work In The Aquarium

How to install the pump in an artificial reservoir? After the device has been purchased or designed independently, it is necessary to carry out the correct installation. There are devices that can be installed inside the reservoir, but this applies only to compact aerators designed for small-sized aquariums.

If the choice fell on centrifugal pumps, the installation of a water pump in an artificial reservoir should be carried out directly into the water near the heater, which will ensure uniform mixing of the liquid during heating. This feature is important when keeping those fish species that are particularly sensitive to any temperature changes. Above the surface of the water are pumps with less functionality and more simple in their design.

The noise of the water pump is a natural phenomenon, but it does not suit many, and therefore the question arises how to make the air pump for aquarium silent? First of all, you need to choose the right surface on which it will be installed. Good soundproofing materials, in addition to the above, include foam and foam. Which one is better, you can choose by experience.

Regardless of the model chosen, the water pump will still be clogged and require timely maintenance. From this it follows that all fasteners during installation must be easily accessible, so that if necessary during temporary dismantling did not arise difficulties.

Now you know not only about why you need an air pump in an aquarium, but also about making such a device yourself. Be sure to pay attention to the location of the device during installation, so that when it is turned on, it emits a minimum level of noise. Based on the foregoing, the choice of aquarium aerator is greatly simplified, which will reduce possible difficulties to a minimum. Properly selected water pump will serve for a long time and efficiently, without causing problems to the owner.

Many manufacturers provide a wide selection of water pump for the aquarium. The acquisition of such a device requires a careful study of the models and their characteristics. The most important ones are as follows:

  • performance;
  • power;
  • the volume of the aquarium;
  • manufacturer.

When choosing a water pump for an aquarium, several factors must be taken into account. Not every campaign produces quality products. With a constant supply of oxygen to the tank, aquarium inlet pumps should have good power. When choosing a device you need to pay attention to its performance and characteristics.

Among the well-known brands of aerators are the following:

  1. Schego water pumps.
  2. Collar.
  3. Aquael

water pumps company Schego, which manufactures devices for any type of aquarium. Depending on the volume of the tank, you can purchase a device with different power. Portable Schego optimal aerators are manufactured that are powered by alkaline batteries. They are convenient when moving or lack of access to electricity.

  • The device works silently.
  • The device is equipped with a mechanism that allows adjustment of the oxygen level.
  • High power allows you to set the sprayer to a depth of 5 meters.
  • The model can serve several aquariums at the same time.
  • The dense filter allows to save a spray from hit of dirt and dust.

The Ukrainian company Collar produces good water pumps, distinguished by their reliability. Designed for a small aquarium up to one hundred liters. It can be installed to a depth of 1 meter. The use of a high-precision air chamber made it possible to achieve a low noise level when the device was operating. Quite powerful with compact dimensions.

The air water pump from the company Aquael is one of the most common devices. Takes the leading places in ratings of water pumps. Devices of various capacities are produced, which allows to choose a model for aquariums of any size. Suitable for freshwater and saltwater reservoirs. If necessary, you can replace the prefilter. Equipped with two air channels.

Possesses such positive qualities:

  • Compact size.
  • Low noise during operation.
  • Existence of the valve for adjustment of power.
  • There is an LED indicator that allows you to track work.
  • Low power consumption.

It is necessary to approach the choice of the aerator with care. Some models can not equip the tank with the necessary level of oxygen, because they do not have the necessary power. The noise level and dimensions of individual models are not suitable for some aquarists. Studying the positive aspects and characteristics of various devices, selects the best air pump for the aquarium, suitable for the parameters for your tank.

The answer is obvious to everyone who has seen this device in operation: it increases the oxygen content in aquarium water. Water in a stationary state may eventually turn into a kind of swamp.

And, as a result, to the disease, and in the worst case to the death of the inhabitants of the aquarium. The air pump, supplying air to the water, enriches it with oxygen, creates air and water flows. This process is called aeration, and such water pumps are sometimes called aerators. Simply put, this is an air pump.

battery-operated air pump for aquarium

Aerators for aquariums of any type can be powered both from the 220-volt network and from batteries. The latter option is preferable only for traveling a considerable distance, or in conditions where electricity often disappears. the aquarium inlet pump with batteries is characterized by high cost at low power and high level of noise.

What should be considered when choosing a water pump?

How to make a choice so that it is correct, what nuances and peculiarities should be paid attention first of all? First of all, you need to know the volume of the reservoir for which the device is selected. If the displacement is unknown, it is easy to calculate, removing the measurements. An important parameter is the depth of the aquarium, called the height of the water column. When buying the equipment in question, as a rule, an instruction should be attached, indicating the characteristics of the pump, such as:

  • performance in l / h;
  • power in watts;
  • pressure in MPa;
  • indicates the presence of an air filter;
  • air flow is regulated or not;
  • number of channels;
  • dimensions.

Separately, it is worthwhile to dwell on performance, since this is quite an important parameter: it means how many liters of air a pump can supply in a certain amount of time. Based on the listed characteristics, it will be much easier to choose a water pump. By the way, an aerator for the aquarium may not be necessary, it depends on the type of fish that the reservoir is inhabited. For example, macropods, pearl gouras, speckled catfish and corridors breathe atmospheric air.

In this case, a water pump for a round aquarium is mandatory, and the instrument must be labeled "for round aquariums". Choose it on the same principle as the pump for conventional reservoirs. So, for an aquarium with a volume of 20–40 l, a pump with a minimum capacity is quite suitable.

The air pump for the aquarium is designed to provide enough comfortable conditions for the fish to live. This equipment conducts additional aeration of water, regardless of the capacity of the aquarium. If an internal air water pump is installed, then you should not worry about the health of the fish.

But first you need to choose the right water pump. But how to do it? Which is better? After all, there are several different types, in addition, each manufacturer offers its own models with individual characteristics. Therefore, it is important to understand what you should pay attention to when choosing a water pump.

Which surface to install?

To reduce noise, the instrument is used far from every surface. When installed in a plastic aquarium cover, the pump enters into resonance with the pump. The same effect will be observed when installing the device on the glass, which covers the reservoir. You can get out of the situation by placing the device in something solid and dense, for example, put it on a wooden shelf near the aquarium, hide it in a closet, etc.

To combat noise, it is recommended to install a water pump on a material with noise absorbing properties. There are many of them: foamed rubber, polyethylene foam and others. With their acquisition of difficulties should arise. If you can not buy them, you can take a rubber pad for a computer mouse, which I do not use.

The steps listed above will help not only to reduce the level of vibrations, but also prevent a premature exit of the air pump. In addition, it is recommended to periodically check all aquarium equipment, carry out preventive cleaning procedures in order to avoid possible damage and burnout.

It is important and properly install the device. First you need to decide where it will be – above the water surface or in a special tank outside the aquarium. Installing a water pump in an aquarium, especially a submersible one, is also carried out taking into account the need to clean the device – it is important that there be no problems for temporary dismantling.

Install the pump in the aquarium can be easily subject to the instructions. The mechanism must be put on the shelf near the tank. In case of its absence, attach the device directly to the wall of the aquarium using suction cups. The mechanism should be installed in such a way that the sprayer and non-return valve could touch the bottom of the container or be closer to it.

Some aerators operate on alkaline batteries, but the bulk is powered by a current source, so the device needs to be installed closer to the outlet.

The sprayer must be attached to the wall of the aquarium or to its bottom. This is done with the help of suckers. After that, attach the tube to the sprayer and water pump.

To maintain biological balance, the aquarium will need help. It is necessary to consider each aquarium as a complex organism, the viability of which can and should be maintained with the help of equipment. This refers to the basic equipment, which is necessary for each aquarium, and additional, which is installed at the request of the owner of the aquarium.

Water pumps belong to the main equipment, as well as filters, water heaters, lamps. What kind of air pump is needed for an aquarium depends on the size of the “reservoir” – the larger the volume of the aquarium, the greater must be the power of the water pump. The water pump aerates the water, that is, saturates it with oxygen.

In the daytime, living plants absorb carbon dioxide and emit the necessary oxygen for plants and aquarium inhabitants. At night, both plants and fish become oxygen consumers, because in the dark time plants do not photosynthesize.

So, at night in the water increases the level of carbon dioxide – an additional influx of life-giving oxygen is needed. Water pumps pump air into the aquarium water. From the side it looks like streams of bubbles that rise from the bottom of the aquarium. The smaller the diameter of these bubbles, the more gas they give into the water. In addition, a running water pump improves the circulation of water, thereby equalizing the temperature in different zones. How to install a water pump in the aquarium

The water pump is recommended to be installed so that it is above the water level and outside the aquarium. If it is not possible to install a water pump above the water level, it is necessary to additionally equip the device with a check valve. The check valve prevents the flow of water in the opposite direction – after all, the water pump installed below the water level can start to receive water from the aquarium.

How to make a water pump?

If you are not satisfied with the noise from the work of the factory device, you can make an aquarium inlet pump with your own hands. There are many variants of a self-made construction, therefore we will consider some of them. For the first product, you will need a 12V electric motor, an eccentric and a pump. The sequence of steps for making the following:

  1. We connect power to the electric motor. This can be done both with the help of batteries and the power supply for the required voltage. It does not make sense to use powerful engines, since there are no advantages from using them, but the level of external noise will be noticeably higher.
  2. To the surface of the engine fix eccentric. With it, the pump will be set in motion and ensure the circulation of water in the aquarium, saturating it with oxygen.

This homemade air pump for the aquarium is noiseless and quite suitable for use in living rooms. If desired, it can be additionally equipped with a potentiometer to reduce and increase the engine speed, thereby adjusting the supply air. If the noise level is not an important component, then a different pump design is done as follows:

  1. For the assembly will need an electromagnet of 220 V.
  2. The pump is connected to the electromagnet, under the influence of which the membrane begins to move with the same frequency, which leads to the inflation of air.

However, the operation of an electromagnet creates some sound, which makes an air-water pump based on it less attractive. On the basis of this, a different design is selected or noise reduction measures are taken. Knowing how to make an air pump for an aquarium with your own hands, you can save a considerable amount of money, which is good news especially for novice aquarists.

If you do not want to design something yourself, you can purchase a mini air pump for an aquarium with a piezo element. Such devices are also called piezo-air pumps: they are now recognized as the most silent. Structurally, the pump is made of a generator and a piezo-element, which makes oscillatory movements. Since the device is new and not so many aquarists used it, its resource is not yet known.

It is only clear that the ingress of water to the internal mechanism will lead to damage to the electronic part, the failure of the piezoplates. So choose for yourself: take a time-tested device or a novelty that attracts attention with its compactness and quiet operation.

How to remove pump noise?

a water pump in an artificial reservoir should work almost constantly to maintain an optimal microclimate. In summer periods, aeration is carried out more often and longer, since at high air temperatures, oxygen is consumed faster. However, some lovers of aquarium living creatures say that they use a water pump 2 times a day, including during the day and in the evening for 20 minutes, but much depends on the type of fish.

Thus, it will be possible to significantly reduce the noise level, and how much depends not only on the installation site, but also on the additional measures taken. For the high-quality functioning of the system, it is necessary to install an air duct that supplies air from the air pump to the aquarium. To reduce the shock wave from the electric motor, for the purpose of additional protection, you can use a packing film with air bubbles, and then place such a device in a wooden box, choosing the right size.

The air flow directed to the pumps in the reservoir must correspond to the volume of the aquarium and not be excessive. This suggests that before making a water pump for an aquarium, you need to decide on the displacement of the tank. In most cases, a small 12 V motor will be more than enough. Selecting the engine you need to know that the use of parts of high power can harm the underwater inhabitants: with constant circulation of water with high intensity disrupted processes in the life cycle of the fish, which can lead to their death.

Therefore, in the daytime it is better to turn off the water pump in order to avoid an excess of oxygen. Some lovers may be wondering how to increase the power of the aquarium water pump? In order to give an answer to it, you need to decide in order to increase this parameter. As a rule, if it is really necessary, it is better to purchase a new pump than to engage in any alterations.

Water pump performance

The main parameter that indicates the amount of air distilled by the device over a time interval. Optimum performance depends on the population density of the aquarium and their species. The value of 0.5-0.8 l / hour per liter of “can” volume is considered traditional. After a simple calculation, you can determine that for a 100 l aquarium you need a capacity of 50-80 l / h, and for 300 l – 150-240 l / h. The presence of the biofilter in the “bank” increases this value.

This characteristic determines the performance and maximum amount of energy consumed. In addition, the depth of the device depends on the power. The deeper you intend to locate it, the higher should be this characteristic. Widespread are models with a capacity of 2 to 11 watts. The following models of water pumps are considered to be the best in this category.

The water pump is chosen according to the size of the aquarium itself. If it is large, then there will be no particular problem in this matter. What to do if the aquarium is a very small volume? It is necessary to select compact aquariums. In most cases they have not very high performance and power. In addition, almost all compact models are unable to regulate the air flow, but for small aquariums this is not particularly necessary.

Ways to reduce noise

There are a number of rules, compliance with which will ensure a quieter operation of the device, allowing to reduce vibration:

  • timely care of the sprayer;
  • installation of a water pump above the water surface;
  • the device is located on a flat and hard surface;
  • the use of the substrate under the water pump, which plays the role of a silencer.

Let us dwell on each of the points in more detail so that the question of how to reduce the noise of a working device does not cause unpleasant sensations. First of all, you need to make sure that the sprayer does not need to be replaced. To do this, the part must be lifted to the surface, disconnect the air supply tube and blow into the stone hole. Normally working sprayer must pass air well. If this is not the case, there will be considerable resistance.

In most cases, the stone has to be changed about once a year, since it is clogged with organic matter, fish waste, bacteria and other dirt. If the reservoir is overpopulated with animal life, the water in it quickly becomes cloudy and the filter is absent, then the sprayer will have to be changed often. How is this related to noise?

If you remove the check valve from the aerator and install the pump above the surface of the water, this will reduce the pressure on the device, reducing the noise. Experienced aquarists install the device above the water level in cases where power outages are possible to prevent water from entering the diaphragm. If water gets inside the device, it will lead to its failure.

In the event of a water breakdown, the room may be flooded, with serious consequences, such as repairs, trials with neighbors, etc. If the water pump cannot be installed above water, it is recommended to use a good quality non-return valve. It is also worth considering that such a detail creates an additional load on the included pump.
