Aquarium Inlet Pump

Now on the market are water pumps of three types:

Water piston pumps differ in high performance and reliability. Such water pumps are installed at a high density of fish landing or to saturate large volumes of water with oxygen. For example, a piston water pump model BOYU ACQ-012 ( with a capacity of 170 l / min can be installed in a tank with more than 10 tons of water. Another use of such water pumps is to install on aquarium stands with a large number of aquariums. The distribution of oxygen in individual aquariums is done with metal flutes.

Membrane Water Pumps most often found on sale and are not very expensive. Membrane water pumps, this is the main choice of aquarists. Membrane water pumps come in many shapes, colors, sizes, but they have one technology for air supply. To reduce the noise level, many manufacturers make minor changes to the materials and housing of water pumps. Membrane water pumps can be with one or more outlets: the SC-3500 with one outlet and its older brother SC-7500 with two outlets. On one outlet, you can connect a conventional air spray, and the second decorative spray.

Water pump performance

The first thing you need to pay attention to when choosing a model of a water pump is performance. The instructions indicate this parameter as a certain number of liters / hour, liters / minute or milliliters per minute.

Power aquarium water pump

The more powerful the water pump, the greater its performance. This characteristic is described in the descriptions as a certain number of watts (W). Here, only common sense and nothing else – in a huge aquarium with a demanding oxygen content, fish need a powerful water pump, a small 1.5 W water supply diaphragm pump simply cannot cope with the task. A small nano aquarium has nothing to acquire a huge piston water pump with a capacity of 100 liters per minute. Given that water pumps work around the clock, all 365 days a year, it is worth thinking about the cost of electricity.

Hello, dear readers of the site Today I propose to make water pumps for our attention. Let’s look at what these devices are, why they are needed, how to use them and install them in an aquarium.

general information

A water pump is a device that is capable of creating air pressure that is sufficient to purge the entire volume of the aquarium with air. For these purposes, you can also use internal filter pumps (how we used them for this purpose in the article “Installation options for the internal filter”). But today we will analyze exactly the use of water pumps.

The purpose of water pumps is one – the organization of aeration in an aquarium. During which, above all, water is saturated with oxygen. Rising to the surface of the bubbles lead to the mixing of water layers, going to the surface destroys the bacterial film, and can also serve as a "transport" of water in the airlift filter.

The main division of vodoshnyh pumps into types occurs according to the principle of the mechanism that creates pressure in the system and which are:

Membrane type

Piston type

Aquarium Inlet Pump

Membrane Water Pumps

The most commonly used are membrane water pumps. This is due to their simplicity and simplicity of design. The main part of these devices is the membrane. This is a cuff made of rubber or any other elastic material, which is internally connected to the air outlet of the device. In order for air to be supplied in one direction only, two check valves are used. For the membrane to start creating pressure, it needs to be given a reciprocating motion. This role is performed by an electromagnet, which magnetizes with the frequency of the alternating voltage applied to it and is connected to the membrane with a lever. All structural elements are mounted in a single compact case.

The advantages of such structures are:

Ultimate simplicity mechanism. The absence of a large number of moving parts makes the design very reliable. In such vodshnogo pumps simply nothing to break.

Lack of serviceable parts. The only serviced part is the air filter, which are equipped with some models and in the case of pollution is replaced by a new one.

Sufficient performance for most users, which is combined with compact size. There are water pumps with a capacity of up to 600 l / h. At the same time, overall dimensions allow not to select a special place for their placement, but to place them in the pedestals under the aquarium or directly next to it.

Low power consumption. A water pump with a capacity of 90 l / h has an energy consumption of about 3 watts.

Low cost of membrane type water pumps as compared with piston models.

But the disadvantages of these devices are also significant:

The main drawback is the noise. Because of the movable lever that deforms the membrane, noises and vibrations occur in structures of this type. Designers go to all sorts of tricks to reduce them: the soft shock-absorbing legs, the horizontal and vertical position of the membrane, different shapes and sizes of cases are used. However, these measures can only reduce the negative manifestations, as they are a consequence of the design features. We can say that the best in noise are models in which two balanced membranes are applied.

The elastic membrane undergoes constant alternating loads, with the result that over time it begins to lose elasticity and crack. Therefore, after a certain period of use of a water pump, its performance drops, and, after the membrane is destroyed, the device stops working. True, this disadvantage is more than compensated for the low cost of the device itself.

Piston water pumps.

Piston-type air pumps are structurally more complex. They are equipped with an electric motor that rotates the flywheel, which drives the piston located in the cylinder. The piston reciprocates and, with the aid of a check valve system, supplies air to the output line. All elements are structurally made in one case. Let’s consider the advantages and disadvantages of such structures.

The advantages include:

High performance. Devices of this type have much higher power and performance. Able to blow large volumes of water at a substantial depth. Often used to maintain multiple aquariums. It can easily stretch the maintenance of small ponds, as there are models with a capacity of about 17,000 liters / hour. They can be used for servicing several aquariums using one device, which is more profitable than using several membrane-type water pumps. The noise level that can be created by 5-6 membrane water pumps installed in the same room is quite high.

Piston water pumps have much lower noise levels than their membrane counterparts. The design here has a significant impact. If the manufacturer does not save on the size of the piston and the quality of the seals, the required performance is achieved at a lower speed of rotation of the electric motor, which has a positive effect on the noiselessness of a particular model

Of the minuses can be identified:

The price of piston water pumps significantly exceeds the cost of the membrane.

Larger dimensions and weight require more careful selection of the device placement location.

A more complex design than that of a membrane type water pump can potentially affect the reliability of the product. Although much depends on the design solutions and materials used by the manufacturer.

Which to choose?

The choice of a particular type of water pump depends on the requirements that you present to the product. For home use in most cases, a device of membrane type is sufficient. True, in this case you will have to take care of the installation place where the noise background will not prevent you from enjoying the beauty of the aquarium.

Also, when choosing a particular model, pay attention to the performance of the device. The main problem here is that the manufacturer often indicates maximum values ​​measured during installation of the device without any spray equipment and supply systems. Connecting a simple hose to the water pump will reduce air flow. As a result, the amount of air pumped through the water, expressed in liters / hour, will be the smaller, the higher:

feed system resistance.

sprayer resistance.

height of the water column in the aquarium.

The number of serviced tanks.

Feed System Resistance consists of the resistances of the hose, valves, adapters, check valves and other equipment mounted between the pump and the sprayer.

Aquarium Inlet Pump

Spray resistance – This is another powerful factor leading to a decrease in the productivity of the water pump. For more intensive saturation of water with oxygen, a nebulizer is required, which forms small air bubbles. The smaller they are, the more effective this process is. The problem is that as the size of the bubbles decreases, so does the resistance of the sprayer.

Water column height in the aquarium also affects the efficiency of the aeration process. The deeper the sprayer is lowered under water, the more intense the process, however, increasing the depth drastically reduces the air supply.

The number of serviced tanks significantly reduces performance, requires the installation of adjustment valves, which also add resistance in order to adjust the flow to each individual aquarium. Multichannel water pumps are available. They have several air chambers that operate independently, and each can serve a separate aquarium.

When a certain amount of three resistances is reached, the air supply may stop altogether and the device will run idle. The exit consists in reducing the length of the air supply line, switching to a sprayer of a coarser structure, or reducing the depth of immersion of the sprayer. It is also possible to choose a more powerful model of a water pump. It is worth mentioning that it is better to purchase the device with a margin of power. This will help you in the future to avoid replacing an already purchased product when you want to expand your aquarium farm or switch to large volumes.

How to install?

It is better to install the water pump in places that are closed from view so that it does not spoil the appearance of the aquarium. Also it is worth remembering the noise created by the device. Placing the product as far as possible from the place of rest will significantly reduce the load on your hearing. Not a bad solution would be to install the device itself in a non-residential area (for example, in the corridor), in this case, you must pass the connecting hose through the hole in the wall to the aquarium. You should not install the device outside the window, since large temperature fluctuations negatively affect the state of the membrane and thereby reduce the service life of the device. The most silent can be called models produced by firms Fluval and Schego.

Aquarium Inlet Pump

It is also worth mentioning that almost all manufacturers of water pumps in the documentation for their devices prohibit their installation below the water level. This is due to the fact that if the water pump stops, the water can flow by gravity through the air hose, overflowing the aquarium, which will lead to flooding. If it is not possible to install the device above the level of the aquarium, it is necessary to install a non-return valve in the open air supply. This miniature fixture will save you from many problems. The principle of its operation lies in the fact that the air can freely pass towards the aquarium, but in the opposite direction the valve is always closed.

In addition, I recommend you to experiment with the method of installing a water pump. If the model is noisy when installed on the legs, try to hang it. Choose a place where it stands, so that there is no resonance.


Sprays are used to create a stream of air consisting of small bubbles. The smaller the size of each individual bubble, the more surfaces of contact of air with water, and therefore more aeration occurs. Sprays are made of natural stone, ceramics, wood. Differ in shapes, sizes, color. They can be a small cylinder or a complex system of tubes that must be attached to the glass by suction cups. It is worth noting that they form the smallest bubbles of wood sprayers, however, due to their dense structure, they require the most powerful water pump. Small holes in the nozzles become clogged with time, in which case they must be replaced.

Why do you need a water pump in an aquarium?

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

Aquarium Inlet Pump

.The main requirements that must be placed on the device when choosing it

Often the aquarium is in the same room where people relax. Therefore, for the aquarium it is better to choose a silent water pump. This device operates continuously. To reduce the noise level of the device, you can remove it into the cabinet. But then you need too long duct. Therefore, it is worth thinking carefully before making the water pump silent, by isolating it. It is better to purchase a silent device at once. The air pump for the aquarium is the most silent. Water pumps should have a smooth adjustment of the air flow. Such a device can be easily adjusted to a different number of filters and nozzles. The power of the water pump is calculated on the basis of the following parameters: 0.5 l / h per 1 l of water. This is the way to solve the question of which water pump is better suited for a specific tank capacity. For a large aquarium (over 100 liters) use a piston water pump. For such an aquarium, it is better to take a device with low-voltage power (12 volts). In the event of a power outage, it can be connected even with a car battery. You can make a quiet water pump using old equipment yourself. So, in order for a home-made device to work as quietly as possible, you will need a wooden box and a box from under the film. In this case, a quiet water pump is obtained by compensating the shock wave with a jar. The very same self-made water pump hides in a wooden box.

Also, water pumps are adjustable and not adjustable.

Those. on the housing of the water pump A special regulator is provided which reduces the supplied voltage, as a result of which a smooth adjustment of the air supplied by the pump takes place.

It should also immediately be said that modern water pumps are divided into several groups, for an aquarist they can be divided as follows, first of all it:

– water pumping stations
– professional water pumps
– water pumps for general consumption
– autonomous water pumps

Aquarium Inlet Pump

How to install a water pump in the aquarium?

Install a water pump in the aquarium is quite simple. First of all, it is necessary to determine the place where it will be located. This may be the aquarium itself, a cover or a table. The device is placed on top of the water, or below the water level, but then a non-return valve is always installed on the air duct. It is desirable that the aerator is located next to the heater. So the heating water will mix, and the conditions for the fish will be the best.

When the noise of a running water pump causes discomfort, it should be placed on foam or foam rubber. This will reduce the noise, but will not give 100% of the result. Some act cardinally: put the device away and stretch a long hose. Any water pump needs to be cleaned periodically. If this is not done, the performance will decrease and eventually the device will break. Also pollution increase the noise level.

Types of water pumps

The first type of pump delivers air through the movement of special membranes that allow air flow only in one direction. Such an aquarium inlet pump consumes very little power and works with low noise.

The main disadvantage of this device is low power. Aerator is not suitable for large containers. However, for example, for a 150-liter home aquarium, a small membrane silent water pump will fit perfectly.

Another type of aquarium aerators – piston vodushnye pumps. From their name it follows that air is pushed out with the help of a piston. These aerators are more expensive, but their advantage is high performance and durability.

True, the noise level of piston vodoshnyh pumps is slightly higher than in devices of the first type. Such aerators are usually installed in large aquariums or columns.

Home aerators of both types are both powered by household electrical network, and from batteries. Each aerator kit includes a flexible hose from which pumped air comes out.

What is the battery powered water pump used for?

There are situations when urgent transportation of fish is required. However, do not deprive the fish of such important oxygen for them. Otherwise, they may simply die. You can use the road device for a small aquarium. Such equipment operates on batteries, which are very easy to replace at the right time. A water-powered pump with batteries allows you to protect against the death of fish that are outside the stationary aquarium. Such equipment has small dimensions, so taking it with you on a trip is very convenient. A battery-powered device may also be necessary if the power is often cut off in the room. Such a device is recommended to keep in reserve absolutely all aquarists. This is due to the fact that even short-term oxygen deprivation is fraught with fish for death. The question of how to choose a water pump, even experienced aquarists ask. When choosing a water pump, it is necessary to focus not on its price category, but on the amount of water that it can drive in one hour. It is desirable to acquire powerful silent water pumps. You can use a homemade device.

Aquarium Inlet Pump

The required capacity of the water pump depending on the volume of the aquarium

Productivity of the installed water pump depends on the volume of the aquarium. Dependence is directly proportional – the larger the aquarium, the greater the performance of the water pump. The optimal performance of a water pump is 0.5-0.7 liters of air per hour per liter of water. But, this is the bottom bracket. As a rule, it is recommended to purchase high capacity water pumps. Why? For example, you decide to install a second nebulizer in the aquarium. This, as you understand, requires additional power from the water pump and additional capacity. More powerful water pumps need to be bought in those cases if the aquarium is high. Here the water pump will need to overcome the water pressure. In addition, the power of the water pump also depends on the diffuser. The smaller the holes, the greater the pressure necessary to create a water pump.

Disadvantages of water pumps

Main lack of water pump – this is noise. No matter how the manufacturers struggle for noiselessness, they have so far failed to win this fight. Yes, it was possible to reduce the performance of this parameter to 25-30 dB, but it is all the same, quite a lot. As a rule, aquariums are installed either in the bedroom or in the nursery, and since the water pump sometimes works around the clock, its noise in the silence of the night is very noticeable. The craftsmen are hiding water pumps in self-made soundproof boxes, which is a good way out of this situation.
The second drawback is the work of electricity. And how do you know electricity and water are incompatible concepts. Therefore, when installing and operating a water pump, it is necessary to exercise elementary caution.

Water pump care, preventive maintenance

To work flawlessly, a water pump needs care.. It consists in the following:
– regular replacement of air filters (if they are available at its entrance);
– control and replacement of rubber membranes (often because of the rupture of the membrane accounts for the entire water pump, as a repair kit is very difficult to find for a particular model);
– regular cleaning of the diffusers (pull out and rinse in clean water, thereby reducing the resistance of the diffuser);
– monitoring the condition of air hoses, and replacing them if necessary.

Silent air pump for aquarium

An air water pump is an apparatus designed to provide aeration of water, enriching it with dissolved oxygen. This device for a home aquarium is a must, as the glass pond is a closed space in which the fish may not have enough oxygen.

The principle of operation of the water pump for the aquarium

The operation of the device is as follows:

  • Submerged pumping tubes intensively release air bubbles that enrich the water with oxygen molecules. The air pressure is regulated by special valves and clips.
  • When the device is operating, ripples appear on the surface of the water, which increases the interaction area between water and air, which contributes to additional water saturation with oxygen.

A water pump mixes layers of water in an aquarium, preventing its flowering and deterioration. The operation of this apparatus is called aeration. Its main purpose is to provide the most favorable habitat for fish and preserve their health.

For aeration of the aquarium, air nozzles are attached to the airway tubes, most often made of a white grinding stone or abrasive substance. Located at the bottom of the aquarium, they emit many air bubbles, creating a very beautiful decorative effect.

Aquarium Inlet Pump

The smaller the size of these bubbles, the greater their total area, which is more favorable for aeration of the reservoir.

Do not use a water pump all the time. It is enough to turn it on twice a day for 20 minutes. In the summer, when the air temperature rises, the water also heats up and spends oxygen much faster, so the device should be turned on more often and for a longer time.

Varieties of water pumps

Aquarium inlet pumps are of several types. The most common and well-known for a long time are:

Quite recently, silent water pumps for the aPUMP aquarium have appeared on the markets. In addition, it is possible to saturate water with oxygen using conventional aquarium pumps or aero-lift filters.

With all the variety of models of devices, their main drawback is the noise they make. If the aquarium is in the bedroom, the noiseless operation of the device is one of its most important qualities. Unfortunately, a completely silent air pump for an aquarium does not exist, since the principle of any kind of apparatus is based precisely on vibration.

Diaphragm water pump

Air supply in such a device occurs through the movement of special membranes, which work only in one direction. The device consumes a little electricity. In addition, it is a relatively silent air pump for an aquarium.

Aquarium Inlet Pump

Its main disadvantage is low power. Such an aerator for large containers will not work. However, in a home aquarium up to 150 liters of a small membrane device can be put.

Water piston pump

It is also a silent air pump for the aquarium. The air in this model is supplied with a piston. Such devices have a long service life and high performance. Due to their high power, they can be used in large aquariums.

Both types of home aerators are powered from a household power supply or from batteries. Each device comes with a flexible hose for pumping air out.

Recently, the competition piston devices made piezo-device. This is the most silent air pump for the aquarium. However, he also has a drawback – he is thin and does not put in a tank more than 200 liters.

Aquarium pump

To saturate the water with oxygen is often used aquarium pump. This small device has 2 functions – water saturation with oxygen and its purification. Pump acquire for large aquariums. This device does not make much noise as it is immersed in water. The only thing is that a light specific whistle publishes a tube for drawing air from the surface. But this problem can be solved. In modern models, pump tubes are provided with a cap. If you change its position, an obsessive noise can be significantly reduced and even get rid of it.

Aquarium Inlet Pump

How to choose a water pump

The most important indicators of aquarium water pump:

  • power;
  • noiselessness;
  • durability
  • price of the device.

For aquariums located in the bedroom, choose an air pump for the aquarium silent air. For large tanks, you need a high power unit.

Aquarium Inlet Pump

For medium-sized aquariums fit any model. The most popular and common brands are JBL, Aguael, Hagen, Tetra.

The smallest and most silent air pump for the aquarium is aPUMP, manufactured by COLLAR and intended to supply water with the most vital and necessary element – oxygen. Used for containers from 10 to 100 liters and a height of water column up to 80 cm.

How to reduce the noise level of a water pump

Consider ways to make an aquarium air pump silent.

  • Styrofoam;
  • dish sponge;
  • foam rubber;
  • instruments.

We open the housing of the water pump, we study its structure and the location of all the details. The cause of cod may be a membrane that is in contact with some convex part. Carefully do the undercut of the protruding part of the case or cut out the area that prevents the membrane from moving freely.

To reduce the noise of the device can be, if you put a dish sponge under it, which will absorb the sound.

Also, the water pump can be installed in a soundproof box or wrap it with foam rubber and secure with rubber bands.

Aquarium Inlet Pump

The cause of the instrument noise may be clogging or weakening of the internal parts. To fix the situation will help his cleaning and fixing loose details.

Making a silent air pump for the aquarium with your own hands

If you know the basic principle of the device, you can assemble it yourself. First, the water pump takes the air in itself, and then gradually feeds it into the aquarium.

In order to assemble such a device, you must prepare:

  • rubber chamber;
  • manual or pedal pump;
  • tee (three-way tap);
  • plastic tube from a medical dropper, always with a clip.

For the manufacture of a water pump from the tee, we take three tubes: the first to the manual (or pedal) pump, the second to the rubber chamber, the third made from the tubing with clamp, will be used as a hose from which air will flow into the aquarium. We end up closing the end of this tube with a cork, and in front of it we pierce several small holes with a needle in the tube itself. Exactly from them air will go out. It is important to ensure that all connections are tight and reliable.

The principle of operation of such a self-made water pump is the following: first, a tube leading from the pump to the chamber will be used to collect air. Then, when the air is collected and the chamber is filled to capacity, this tube will stop working, and another one leading from the chamber to the outlet tube will start functioning. With the help of a special clamp you can adjust the air velocity, which will go outside. It is best to make the air flow as slow as possible.

Aquarium Inlet Pump

In principle, the water pump is made by hand. The disadvantages of such a device include the fact that the battery should be pumped periodically. For normal aeration of an aquarium with a volume of up to 100 liters, such pumping is performed approximately twice a day. Therefore, a homemade water pump can not be left unattended for a long time.

Why do you need an air pump in the aquarium

The need for such a device in a glass aquarium due to the fact that it is a closed space. As a result, there is a lack of oxygen, which is bad for fish and plants. Because of their waste products, dust, a film on the surface and small debris, water can become like a swamp. To save from such a situation is designed aquarium inlet pump. It performs the function of aeration – the natural saturation of water with oxygen.

Aquarium Inlet Pump

How does the aquarium inlet pump work?

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. Some craftsmen, in this case, independently install special faucets on the air tubes, and replace the aerator itself with an ordinary cooler from a computer.

Aquarium Inlet Pump

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. It is better to leave it in working condition and night. Plants emit carbon dioxide – if the aquarium is densely planted with them, the inhabitants of the reservoir may not live until morning.

Types of air pump for aquarium

One of the main classifications divides aquarium inlet pumps into three main groups – diaphragm, piston and pumps. Their differences are in price, principle of operation and the power of noise. Membrane water pump for fish is also called vibration. It forces air by reducing the elastic rubber membrane due to the transfer of the oscillations of a magnet inside the device to it. Piston work thanks to an electric motor that drives the piston. The pump is a universal device for aeration and filtration of water. It is suitable for large aquariums.


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. It produces not so much noise, but not so cheap compared to the membrane one. Both types of water pumps can be used at once. Piston to include at night, and membrane in the afternoon. The latter consumes less energy.

The main advantages of a piston pump:

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


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.

Aquarium Inlet 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. They "eat" a lot of energy and work no more than 4-6 hours. Then you have to buy a new set of batteries. For this reason, you should not choose such a micro-air pump, if you always have access to the power grid.

How to install a water pump in the aquarium

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. To eliminate the noise from the device, you can arrange it on foam, and in extreme cases – foam. Air ducts and sprayer are placed at the bottom. The tube can simply press a shell or pebble.

How to choose an air pump for the aquarium

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.

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.
