How to install a water pump in the aquarium

Without a water pump it is difficult to imagine the normal functioning of aquarium fish. The effectiveness of this device depends on the correct implementation, so it is very important to pay enough attention to how to install the air pump in the aquarium. In order to effectively accomplish this task, it is recommended to adhere to a number of principles in order to provide all the necessary conditions for the life activity of marine inhabitants.

Recommendations for installing a water pump

How To Install A Water Pump In The Aquarium

The key point when installing the device – the right choice of place in the aquarium. In some cases, the design allows the sprayer to be mounted directly into the aquarium itself, but this is applicable only for compact models that handle small volumes of water. In the case of a large tank, it is best to choose the area near it, it may be a table or a secure fit on the lid.

The functional part of the water pump must also be located in compliance with some principles. In the case of centrifugal pumps, which act as an aerator for the aquatic environment, the installation of a water pump in the aquarium should be made directly into the water column, at a minimum distance from the heater. This is necessary so that when heated, the water is immediately thoroughly mixed and the fish quickly get the necessary microclimate. These conditions are important for those fish that are very sensitive to any changes in temperature and need uninterrupted support for special conditions.

Above the water, as a rule, water pumps of a simpler design and with less functionality are located.

The noise from the aquarium vodshnogo pump is quite natural but removable, with proper selection of the surface on which it will be located. The best sound insulation for an aquarium is foam rubber or, in extreme cases, foam. The first option will be more invisible and reliable, as it is less susceptible to mechanical damage and will not be able to clog the aquarium.

Also, when installing an aquarium pump, it is necessary to consider the cleaning procedure. Any model of the device will be periodically clogged and require timely maintenance, so when installing all fasteners are located in accessible places, so that there are no problems if you need temporary dismantling.

It is worth remembering that for large aquariums a powerful water pump aso 818 is needed, it is easy to install and will last more than one year.

Install the water pump in the aquarium

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. So, if the owner does not want to repair his apartment and the apartment of his neighbors below, he must take care that the water does not flow out of the aquarium through the water pump in case of a breakdown or power failure.

An aquarium in any apartment is a great solution. And from a design point of view – a good thing, and the living creatures in the house is present. Many believe that the fish are very convenient in terms of content. But knowledgeable people understand that this is not the case. Those who are planning to have an aquarium with fish (even exotic ones) in their apartment or country house should read a lot of information, learn about the life of these beautiful creatures and their habitat.

Why do you need an air pump for the aquarium

Without normal water, the fish will not survive, even though they will have the best food and aquarium for 5 thousand American presidents of the evergreens (they are more expensive). Fish habitat is water. It must be clean, contain a sufficient amount of oxygen. Otherwise, the aquatic fauna will hurt, wither and die.

The lack of oxygen changes the entire ecosystem of the aquarium. To survive in such terrible conditions is difficult even for a medical leech. Toads are also demanding on water quality. Especially recommended is the use of aeration for long and high aquariums.

To maintain the balance of oxygen, special oxygen pump installations have long been used. water pumps fill water with oxygen, mix water layers (internal circulation in a closed volume).

It also helps to destroy the bacterial film on the surface of the water, which improves oxygen exchange, heals the water. Of course, water is best enriched with plants, but it may happen that this is simply not enough (plant diseases, death, design features and topography of the bottom of the aquarium).

The components of the water pump for the aquarium

The complete set of a water pumping unit for an aquarium includes such things:

1. Self water pump

2. Air supply hose

Types of water pump for aquarium

Aquarium inlet pumps are divided into two types: piston and diaphragm.

The air supply in piston vodshny pumping systems to the spray nozzle is carried out using a piston. Such water pumps have a large margin of safety and power. The only drawbacks of this design are high noise and they are more expensive than membrane ones.

In membrane vodushny pumping installations, the supply of oxygen to the spray module is carried out using a special rubber membrane. They are not so noisy and for this type of water pumps do not need more power. They are useful for small aquariums. The main factors when choosing a type of water pump are: the volume of the aquarium itself, its location, and the design features of the tank.

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.

When to turn on the air pump for the aquarium

Aquarium inlet pump can work around the clock. There are no restrictions here.

The water pump must be switched on at night when the aquarium plants do not emit oxygen in the absence of light, and also within two to three hours after feeding the fish to avoid the formation of stagnant oxygen-free zones in the aquarium in which the food remains will be processed by anaerobic bacteria, which will cause the smell of rotten rotting water in the aquarium.

There are many different models of air pump for the aquarium, which play the role of an aerator – a device that passes air with oxygen through the water column. It is necessary, because the decorative fish is very demanding to the living conditions. An aquarium air pump helps maintain an optimal environment.

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.

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.

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.

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.
