How To Install A Water Pump In The Aquarium

Water pump function

There are two arguments to the question of whether you need an air pump in an aquarium:

  1. the filter provides a constant supply of oxygen. Under natural conditions, oxygen saturation occurs due to the flow of water. In an aquarium, the process is carried out thanks to live plants as a result of photosynthesis. But it occurs in the daytime, at night, plants and animals absorb oxygen, while releasing carbon dioxide. And without a water pump for an aquarium in this case can not do.
  2. creates an artificial current that prevents water from stagnating and turning into a swamp. This is due to the accumulation of a large amount of food residues and the vital activity of animals, due to dust and small debris entering the water, formed film on the water, and insufficient oxygen concentration.

Therefore, even for a small aquarium with a small number of animals, an air pump in the aquarium should be installed. Due to its lack of fish in the tank can die from oxygen starvation.

In an aquarium, a water pump creates air and water flows, i.e. a process of aeration takes place. The device itself is often referred to as an aerator.

See how to properly install a water pump.

What are the devices for air aeration?

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.

How To Install A Water Pump In The Aquarium

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.

System selection

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.

Choosing a water pumping system is an important point. Before you choose a device, you should consider a few nuances:

The air filter must be adjustable, that is, it will be possible to set the amount of air supplied. The device is used with any number of filters and sprayers. To choose the right air filter, you should consider the principle of operation of the device, the level of noise. Aquarist divides aeration systems into three types: membrane, piston and pump. Varieties differ in price.

Membrane filter

Membrane installation is suitable if you want to save on electricity rates. The device can be installed simultaneously on multiple tanks. Among the positive aspects there are also a long service life, rare failures and the almost complete lack of need for repairs.

The disadvantage of this water pump is one – it is quite noisy. The reason for this is the vibrations that are formed during the process of contraction of the membrane of elastic rubber, as a result of which the magnet oscillates and transmits movements to it. Thus, air is being forced. A membrane device is therefore often referred to as a vibration device.

You can easily make a quiet water pump aquarium with your own hands. To do this, take a wooden box, packaging from film. Place the device in a box, and with the help of a box the shock wave will be reduced. The water pump will be quieter.

Piston aerator

How To Install A Water Pump In The Aquarium

If you want to purchase a silent air pump for an aquarium, give preference to a piston filter. It works by the piston, which drives the engine. The rotation of the shaft create vibrations that carry out the supply of oxygen. Their intensity depends on the power of the device.

In this case, instead of one powerful water pump for an aquarium, two types of aerator can be used at once – a membrane and a piston. Vibration is activated at night, the piston air pump for the aquarium – during the day.

Piston water pumps are suitable for large tanks. Choose a filter that will operate on low voltage power. If a power outage occurs, it will allow the device to start from the battery for the car.

If we compare the cost of the piston and membrane filters, the former is much more expensive, but more reliable and suitable for large tanks installed in rest rooms. In addition, it has a long service life, a high degree of performance. But a piston air pump in an aquarium consumes much more electricity.

The aeration pump coordinates the flow of air in the tanks of different volume, carries water to the filtration system. The pump not only equips water with oxygen, but also contributes to its purification. For large-scale aquariums use a device that carries out a constant circulation of water. The operation of the water pump in the aquarium in the form of a pump is carried out quietly, since the devices are quiet. This is due to the fact that these devices are internal, that is, they are immersed.

Micro Air Pumps

There are types of water pumps that operate autonomously. Power can come from a 220-volt electrical network and from batteries. Mini-water pumps are used when traveling for small tanks. A mini-air pump for the aquarium is also purchased in case of a sudden power outage.

These types of air pump for aquarium have a small power level. It is worth while installing quite expensive. The standalone filter is very loud. Its performance is not longer than 6 hours. After that, the battery charge ends and you have to change the kit. This is extremely unprofitable, so leave the air filter is always on is not worth it.

Another filter characteristic is adjustment. The aerator can be adjustable and not adjustable. On this depends the smoothness of the air flow. In regulated installations it can be reduced or increased if necessary. In unregulated flow of oxygen is fed with the same intensity.

It is important not only to choose a water pump, but also to install it correctly. Before you install a water pump in the aquarium, you should consider a few nuances:

  • Connection begins with a choice of the place for the filter. It can be placed both inside the tank itself, and on the lid of the tank or on the pedestal on which it is located.
  • The installation of a water pump in an aquarium can be either on the surface of the water or with partial or complete immersion. In the latter case, a check valve is installed on the air duct.
  • Next to the water pump, place the aquarium heater. This will allow you to quickly mix the heated water with the cold, and the environment for fish will be more comfortable.
  • In order for silent aeration to take place, polystyrene is preliminarily placed on the pedestal, or the filter is installed in another room, connecting it to the tank with a long hose.
  • Do not forget to periodically clean the water pumping device. Its pollution leads to a decrease in performance. After a while the device will break. Dirty filter and louder.

Why care of the filter is understandable, but how to implement it correctly? This is done like this:

  • in the presence of a filter for air purification, replace it regularly;
  • control the reliability of the membrane parts of rubber and change them in time. If this part breaks, then the entire water pump will most likely have to be changed, as it is difficult to find spare parts for certain models.
  • periodically pull out and wash the diffusers in warm water. This will reduce their resilience and increase the service life of the device.
  • monitor the air hoses. In case of minimal damage, replace them.

Instead of a water pumping system, you can use an oxidizer. It does not need to be plugged into a power outlet and constantly change batteries. In addition, it is the quietest filter for aquariums from all available varieties. It works on chemical reactions: with the help of catalysts, hydrogen peroxide decomposes into water and oxygen. The reaction accelerator can be metals that absorb active oxygen, and the surplus gives into the water.

If it is not possible to purchase a quality water pump, you can make the device yourself and temporarily use it as an aeration system. To create a high-quality filter, you need experience in creating similar devices. Homemade can lead to a short circuit in the water, which can cause the death of not only fish, but also man.

You can make a water pump aquarium with your own hands, but for this you should strictly follow the instructions. In this case, you will not only quickly create a device, but also make it safe. You can build a water pump yourself in several ways. Consider the most simple and affordable:

  • Take a small electric heater and connect it to the mains. The power of the device should not be more than 12 volts. It can be connected to the battery or battery in case of power failure.
    After that, connect the eccentric to the engine. It is necessary for the implementation of the movement of the pump. She, in turn, will carry out the process of circulation of water flows, supplying it with oxygen.
    The advantage of this method is that such water pumps are noiseless.
  • The second method is based on the action of a magnet. Electromagnetic starter must be at 50 Hz frequency. This is enough for 220 volts.
    A pump is attached to the electromagnet. Under its action, the membrane begins to move with the same frequency. Air enters the pump, and as a result, the water is saturated with oxygen. This water pump is quite noisy, consider this fact when choosing a device.

Installation of the aerator in the aquarium

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 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.

How much time should the air pump for the aquarium work per day?

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.

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.


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.

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.


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 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.

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.

The principle of operation of this type of water pumps is based on the movement of the piston, which pushes the air out. Rotational motion of the shaft is converted into oscillatory. This leads to the achievement of the desired air supply. If your fish live in a bedroom or a rest room, then a piston air pump for an aquarium would be ideal in this case.

The main advantages of a piston pump:

  • durable;
  • almost silent;
  • high performance;
  • suitable for large aquariums.
  • consumes a lot of electricity;
  • expensive.

How to install an air pump for aquarium

The rules for installing an aquarium water pump are simple. And yet it will not be superfluous to talk about them. An external water pump is usually placed on the lid of the aquarium. If a sucker was supplied with a water pump for the aquarium, you can place the water pump on the side cover of the aquarium.

At the same time, you should try to place the end of the spray hose as close as possible to the bottom of the aquarium. With this arrangement, air bubbles pass through a thicker layer of water and the saturation of water with oxygen will be faster and more intense.

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.


Otherwise, the diaphragm air pump for the aquarium works. It causes the air to move from the chamber connected to the membrane. It shows pressure drops. They are created by vibrations of the magnet, which also indulge in an elastic rubber membrane. Its advantage is low energy consumption. In addition, such a device can be repaired, although it is often not necessary. He also refers to relatively cheap devices and can serve more than one aquarium. The disadvantage is low power and high noise.

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.

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.
