Air Pump For The Aquarium What It Is For

July 27, 2019

Water pumps for an aquarium are one of the important attributes that ensures the flow of air into the tank. Often, an artificial pool is filled with many inhabitants who do not always have enough oxygen. Plants are not able to provide representatives of the right amount of air, so you need to install a special pump in the aquarium.

Why do you need

Inexperienced owners are confident that the amount of oxygen emitted by plants is sufficient for a comfortable life of inhabitants. Algae form o2, but in a small amount, which is not enough for containers with large volume.

The formation of aquatic ecosystems is adversely affected by:

  • fish excrement;
  • rotted feed particles at the bottom;
  • lack of oxygen adversely affects the formation of the aquatic ecosystem.

Exotic species of fish are fastidious to the conditions of detention, so the lack of sufficient air can lead to their diseases or even death. And also standing water is exposed to the formation of a film on its surface. The air flows supplied by the pump enrich the reservoir with oxygen, which is necessary for the healthy development of the inhabitants. This process is called aeration (air supply to the aquarium). All water layers are mixed together, so that the reservoir will not look like a swamp.

How does it work

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.

Regulated and unregulated

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:

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. If necessary, it is repaired. Among the shortcomings of a piston water pump, there is a high power consumption and an overestimated price.

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. Differs in low cost. Among the disadvantages can be identified high noise and low power. Installing it in aquariums with a volume of more than two hundred liters does not make sense.

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.

Required performance depending on the volume of the aquarium

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.

For small aquariums, up to one hundred liters in volume, an aerator with a capacity of up to 80 l / h is suitable. More capacious tanks will require a device with a capacity value up to 240 l / h.

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.

How much should work

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.

Air Pump For The Aquarium What It Is For

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.

How to choose the top 3

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 devices are equipped with special legs that provide stability. If necessary, they can be hung to the wall. The devices of this manufacturer have a number of positive aspects:

  • 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.

How to install

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.


The main disadvantage of water pumps is noise. Many tank owners install an aquarium pump in soundproof boxes. This partially helps to solve the problem. Some manufacturers make models that are installed directly in the tank. During the day, their work is almost inaudible.

At installation of the aeration device it is necessary to be careful, as the main mass works from electricity. Non-compliance with safety measures is fraught with closure, which will lead to the death of the inhabitants of the reservoir.


Noise during the operation of the aerator brings inconvenience. There is its alternative replacement – the oxidizer. This is a homemade filter aerator for aquarium. With its help, oxygen is supplied to the tank through a chemical reaction. The basis is the decomposition of hydrogen peroxide into oxygen. A catalyst is required for continuous work. His role is played by metals. As a result of the reaction, the catalyst is oxidized and releases oxygen into water. The device is used without electricity. During the work does not make noise.

For the smooth operation of the device care is needed.

  1. It is required to change air filters and rubber membranes in time.
  2. Prolonged use results in contaminated filter.
  3. Holes are clogged and oxygen is poorly supplied to the aquarium. It is necessary to periodically clean.
  4. Sometimes hoses become useless, as crustaceans can damage their claws.
  5. It is necessary to have one more device, in case of breakage of the main aerator.

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.

Air Pump For The Aquarium What It Is For

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.

Air Pump For The Aquarium What It Is For

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.

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.

Air Pump For The Aquarium What It Is For

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.

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.

Air Pump For The Aquarium What It Is For

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 for the aquarium

In nature, saturation of the water column with oxygen is the task of algae. Oxygen exchange between the surface of the water and open air is too slow – the molecules do not have time to sink to the bottom of the aquarium, because it may take a whole month! In an aquarium, densely populated with fish, algae are needed in quantities that are contrary to common sense and aesthetic considerations. At night, photosynthesis stops and plants become oxygen consumers along with other inhabitants of the aquarium. This is where the air pump for the aquarium comes to the rescue.

Due to the effective aeration of aquatic inhabitants, metabolic processes are normalized and the normal functioning of the body is maintained. In water that is poor in oxygen, they become lethargic, faded, often ill and constantly float under the surface, sometimes even refusing food. The lack of dissolved oxygen affects the health of algae and the bacterial component of the biotope. Water begins to turn sour, grow cloudy, becomes a pathogenic environment. It is possible to accurately determine the oxygen content in water and the compliance of the indicator with the help of a special O2 test, available in water testing kits. Some aquarists use a very rough home test with hydrogen peroxide.

an aquarium air pump also improves the circulation of water and complements the filter, increasing its efficiency. Together they prevent the appearance of a matte bacterial film on the surface.

The water lift formed by the device mixes the water and prevents the formation of stagnant areas. He also levels the temperature in the pond, protecting the fish from its harmful jumps. And remember: the smaller the bubbles escaping from the water pump, the faster the oxygen dissolves in the water.

It is for these reasons that aquariums with lilius, cockerels and goura – fish that live in nature in oxygen-poor bodies of water and have adapted to the collection of atmospheric air from the surface, do without a water pump. The unique adaptation mechanism of these fish, alas, is not shared by other inhabitants of the aquarium — algae, snails, and crustaceans. Without an aerator, they quickly become shallow, decay, and even die – because the biological balance, largely dependent on aerobic bacteria, is disturbed.

Step-by-step installation of the water pump

Before buying a water pump, make sure that it matches your electrical network. Detailed requirements and the assembly algorithm of the device are always indicated in the instructions. Carefully familiarize yourself with them and, if something remains unclear, specify how to install the water pump properly at a consultant. Remember that a too powerful water pump can create uncomfortable conditions for the fish – a powerful current can be removed only by clamping the hose. But why pay for electricity and listen to noise? This decision is fraught with overheating of the motor. Our informative article will help you choose the right aerator.

Choosing a place

Air Pump For The Aquarium What It Is For

Traditionally, the aerator is placed above the water level; this saves energy and reduces noise. If you do not follow this rule, water will be poured into the device and spoil it, and then pour out of the aquarium and flood its neighbors. But it is impossible to install an air pump for an aquarium directly on the aquarium’s cover — it produces a perceptible vibration during operation, and in this position it starts to rattle. The most reasonable way to fix it on the wall with a nail, put on a shelf or countertop. Make sure that the water pump is at a reasonable distance from sockets, extension cords, electrical appliances included.

But sometimes this placement of the device is impossible. Yes, and in terms of aesthetics, it would be more appropriate to hide the water pump in the aquarium cabinet. For this you need to purchase a check valve about its installation, we will tell below.

It is best to place the aerator tube next to the water heater for a constant current created by the water pump, which quickly equalizes the temperature in the entire tank.

Mounting selection

Take care of the mounting for the hose and sprayer in advance. These elements are located at the bottom, because it is important to fix them so that they do not float. For this you need aquarium decor – stone slides, ceramic amphorae, snags, shells. If the sprayer emerges, the efficiency of aeration will decrease several times the oxygen simply does not have time to dissolve in water before it reaches the surface.

Installation of the hose and spray

It is best to place the aerator tube next to the water heater for a constant current created by the water pump, which quickly equalizes the temperature in the entire tank. The air intake hose should be brought out of the aquarium, directly into the room. The sprayer is traditionally installed at the rear wall of the aquarium, where it does not interfere with the observation of the fish. Learn more about choosing a sprayer here. The hose itself is usually hidden along it, it is instilled, masked with plants. If you need to replace the hoses, choose only those that are specifically designed for aquarism.

Check valve installation

Air Pump For The Aquarium What It Is For

A non-return valve is used in cases when the water pump is located below the water level. The valve membrane opens only in one direction, allowing water to flow freely into the aquarium and blocking the hose when it moves back. To install it, you must cut the hose across. The closer to the board of the aquarium there is a cut, the better it is recommended to leave a piece that will protrude 3-4 cm above the wall. After both parts of the hose are attached to the check valve nozzles (make sure that the arrow drawn on it is turned towards the reservoir). After the hose is inserted into the water pump, aeration can be started.

Water pump check

If the aerator makes a lot of noise during operation, the stand for it can be cut out of foam, foam rubber or other soft material. If you correctly install the air pump for the aquarium, the effect will appear within a few hours. Observe the behavior of the fish: each species must be kept in its usual habitat. If the bottom fish are trying to keep closer to the surface, it is better to increase the power.

Hello, dear friends!

Today we talk about such a necessary thing, which is called aquarium inlet pump! You have probably heard and even seen this device: in the “Bird markets” aquarium fish sellers often use a water pump in their aquariums. But why does he need this aquarium aquarium pump? And will you need it? That is what this article is about. So!

Bottom filter for aquarium

Aquarium inlet pump is a special device that serves to enrich water with oxygen. How does this happen? And you yourself will take a closer look and understand everything: firstly, air bubbles out of the water pumping tube, which is lowered into the water, intensively leave air bubbles and, as a result, oxygen enrichment of water occurs. And secondly, the water pump creates ripples in the water and thereby increases the surface of contact of water with air, which also saturates the water with oxygen. This procedure (I mean – water saturation with oxygen) is also called aeration. Well, the main “plus” of the water pump is that it mixes layers of aquarium water. Thus, the water in your tank will not become rotten and look like a swamp.

In what cases it is necessary to use an aquarium inlet pump? I will try to answer this question as simply as possible. Suppose your aquarium has a volume of 100 liters and there lives a whole colony of fish in an amount of, say, 50 individuals. The remnants of food, waste products of your fish fall to the bottom and begin to rot. Often, changing the water in an aquarium does not always have the time and effort: try changing the water in a 100-liter aquarium at least once and see how troublesome it is! In rotten water, fish suffer from a great lack of air and can die or become sick. And it is for such large aquariums that the water pumps are intended: they perfectly saturate the water with oxygen! And once there is oxygen in the water, the health of the fish is safe! However, the water pump does not completely solve the problem: you still have to change the water in the aquarium, whether you like it or not!

Now, about when exactly to turn on the water pump: it should not work 24 hours a day! Personally, I use the aquarium inlet pump twice a day: during the day (I turn it on for 20 minutes) and in the evening at 22 o’clock (I also turn it on for 20 minutes). This "airing" of water to my fish very much! The only thing I want to add is that in the summer, aeration should be carried out more often and longer (at high air temperatures, the water in the aquarium heats up and oxygen is consumed faster).

By the way, there is one more “knight’s move” and it is more suitable for lazy aquarists. When it comes time to replace the water in the aquarium, you can somewhat simplify this task. For this you need to collect garbage from the bottom of the aquarium. How to do it? Use a piece of transparent thin hose as a “vacuum cleaner”. The diameter of the hose should not be large: it is better to use a dropper or a hose of a slightly larger diameter (the diameter of an old Soviet penny), but not a watering! Lower one end of the hose to the bottom of the aquarium (just to the bottom: stick the edge of the hose into the ground!), And the other into the empty bucket, which is located below the level of the aquarium. In order for the water from the aquarium to overflow into the bucket, it is necessary to create a negative pressure in the hose. In simple words, I will say this: make a "leak" and the water will begin to flow! The main thing – do not swallow the smelly water. When the water begins to drain into the bucket, use the hose as a “vacuum cleaner”: drive them along the bottom and collect garbage – food residue and other waste. Be careful and attentive: do not pull the fish into the hose! When the bottom cleaning is finished, just bend the hose in the middle and the water will stop flowing! Now look at the amount of dirty water drained and pour as much into the aquarium. After that, turn on the aquarium inlet pump for 15 minutes. Here is a method for the "lazy."

That’s all, friends! I will not list the types of aquarium water pumps, their “pros” and “cons”, etc. etc : You shouldn’t bother yourself with unnecessary knowledge! Everything you need at first – you will learn from my articles! And remember the main rule in any science: do not force events! You will not be able to find out everything about anything – it is simply not possible and not necessary! As the Latins say: “Festina Lente”, which means “Hurry slowly!”

See you in the next articles!

Why is it needed

Living beings always require optimal living conditions for active life and well-being. Aquarium fish are no exception. They constantly need oxygen. But often the aquarium does not have enough water surface and the number of plants necessary for oxygenation. That is why the best solution is to purchase additional devices that saturate the water. This function is performed by a water pump. Here are his tasks:

  1. Providing aeration. The oxygen bubbles rising from the device additionally saturate the water with oxygen.
  2. Stirring the water. Drilling device levels the temperature in the lower and upper layers. If the fish house is equipped with a thermostat that heats some of its zones stronger, others weaker, then the water pump ensures temperature equalization. Circulation does not allow fluid to congestion.
  3. The aesthetics of the aquarium. Rising up, perpendicular to the water surface, air bubbles give capacity attractiveness.
  4. Preventing top film formation. It is usually formed in the absence of a water pump from bacteria and dust on the surface of the water.
  5. Imitation of the flow. For many fish, it is important to stay in conditions close to natural. The device creates a movement similar to the flow in the pond.

Variety of choices

Such devices are also called aerators. Most of them are vibratory machines. The principle of their operation is based on the creation by an alternating current of an electrical network of an alternating magnetic field.

Novice aquarists should be guided in how to choose the right water pump for arranging your aquarium. After all, the market is saturated with a huge range of such products. To understand the choice is not easy.

First of all, we must understand that each such device is designed for a certain amount of water. It is necessary to choose it, proceeding from its thickness. A powerful water pump is needed only for aquariums with a large volume of water. How to correctly focus on the performance of the device? Calculate it simply. It is necessary to multiply the displacement of the aquarium by 0.5 So, on a one-hundred-meter fish house you need an aerator with a capacity of 50 l / h.

For home fish houses often use submersible devices with lighting. They are installed inside the tank. This gives the fish house aesthetics, decorative. At night, a room with such a fish house is filled with a soft light.

If the owner has a need to urgently transport the fish, then a water-powered pump is used. Such a device will be indispensable in situations where power outages are often practiced in the home or office.

If we talk about external water pumps, they are good for aquariums because they are compact, do not clutter up space, are conveniently mounted and easy to use.

Today, small and silent water pumps for the aquarium are very popular. They are recommended to be used in those containers whose volume does not exceed 200 liters. That is, they can be used in the most popular metropolitan fish houses. Such devices are recommended to be included in the morning and in the evening. There is no need for the device to work all day. Such mini-water pumps are actively used for decorative purposes, because many people are attracted by the appearance of flowing oxygen bubbles.

In large aquariums, water pumps create optimal, close to natural conditions for waterfowl.

So, the purpose of the water pump is to saturate the water space with oxygen. Today, an alternative to such a device is the saturation of water with dissolved oxygen using the so-called oxidizers. The principle of their action is the decomposition of hydrogen peroxide into water and oxygen. One refueling stolitrovogo aquarium with such an oxidizer lasts for 2-4 weeks.
