How much should the compressor work in the aquarium


Why a compressor in an aquarium?

All equipment intended for aquariums serves primarily to maintain the stability of an already established biosystem. Beginners aquarists tend to place too high hopes on equipment - they acquire expensive compressors, the best filters, but cannot achieve the desired results.

Why do the fish do not want to multiply rapidly, and the plants are sick and not in a hurry to grow? Despite all the connected first-class equipment, the aquarium does not accept the planned appearance. This happens because first of all you need to wait for the ecological balance in the "running" aquarium, and only then turn on additional equipment.

Filters and compressor for the aquarium do not solve the problems associated with the instability of the parameters of the aquarium. The question naturally arises: why, for example, the same compressor?

Compressor Functions

The compressor provides aeration - it contributes to the saturation of water with oxygen. Oxygen enrichment is achieved by the constant release of a stream of air into the water - from the side it looks like a constantly rising chain of air bubbles. (By the way, flowing bubbles significantly increase the aesthetic appeal of an aquarium.)

Continuous boiling water helps to equalize the temperature of the water. Suppose a thermostat is installed in an aquarium — then certain zones of water heat up more, while remote areas do not have time to warm up. A running compressor improves the circulation of water and helps to even out the temperature. Water circulation in turn prevents water stagnation.

Whether a compressor is needed in an aquarium depends on the type of aquarium, the number of fish living in it and the number of plants. In a small aquarium with few inhabitants, a sufficient level of oxygen can be maintained by the plants, for a larger aquarium a compressor is needed. Moreover, the greater the volume of the "reservoir", the greater must be the capacity of the aquarium compressor.


Why do you need a compressor 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.

Remains of vital activity of small fish, grain of feed, dust, small debris, film on the surface, lack of oxygen can all lead to an unfavorable state of the aquatic environment.

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

.Main requirements that must be placed on the device when it is selected

Often the aquarium is in the same room where people relax. Therefore, for the aquarium it is better to choose a silent compressor. 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 compressor silent, by isolating it. It is better to purchase a silent device at once. The air compressor for the aquarium is the most silent. Compressors should have a smooth adjustment of the air flow. Such a device can be easily adjusted to a different number of filters and nozzles. Compressor capacity 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 compressor is better suited for a specific tank capacity. For a large aquarium (over 100 liters) use a piston compressor. 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 compressor using old equipment by 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 compressor is obtained by compensating the shock wave with a jar. The very same homemade compressor hides in a wooden box.

Also compressors are adjustable and not adjustable.

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

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

- compressor stations
- professional compressors
- Compressors for general consumption
- stand-alone compressors

How to install a compressor in an aquarium?

Install the compressor 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 compressor 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 compressor 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 compressors

The first type of pump delivers air through the movement of special membranes that allow air flow only in one direction. Such an aquarium compressor consumes very little electricity and operates 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 compressor will fit perfectly.

Another type of aquarium aerators - piston compressors. 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 reciprocating compressors is somewhat 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 a battery powered compressor 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. The battery-powered compressor 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 compressor, even experienced aquarists are asked. Choosing a compressor you need 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 compressors. You can use a homemade device.

Required compressor capacity depending on the size of the aquarium

Capacity of the installed compressor depends on the volume of the aquarium. Dependence is directly proportional - the larger the aquarium, the greater the performance of the compressor. The optimum performance of the compressor 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 compressors. Why? For example, you decide to install a second nebulizer in the aquarium. This, as you understand, requires additional power from the compressor and additional performance. More powerful compressors must be purchased in those cases, if the aquarium is high. Here the compressor will need to overcome the water pressure. In addition, the power of the compressor depends on the diffuser. The smaller the holes, the more pressure must be created by the compressor.

Compressor Disadvantages

The main drawback of the compressor - 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 compressor sometimes works around the clock, its noise in the night silence is very noticeable. Craftsmen are hiding compressors 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 compressor, it is necessary to exercise elementary caution.

Compressor care, preventative maintenance

For perfect work behind the compressor, care is needed.. 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, the entire compressor is necessary, since it is very difficult to find a repair kit 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.

Alternative to the compressor in the aquarium

As an alternative to compressor You can offer an oxidizer. It is extremely simple in design and operation of the device. It does not require the supply of electricity or the installation of batteries, and it is absolutely silent because only chemical reactions occur in it. The principle of operation of the oxidizer is the decomposition of hydrogen peroxide (H2O2) into water (H2O) and active oxygen (O), under the action of a catalyst. As a catalyst, there are metals that, when oxidized, take a part of the active oxygen, and the excess oxygen is released into the water.

Aquarium compressor

Every experienced aquarist knows how important it is to have a quality aquarium compressor that is suitable for the size. It enriches the water column with oxygen, does not allow water masses to stagnate, thus avoiding clouding and the development of various diseases and putrefactive processes that may adversely affect the inhabitants of the aquarium.

Types of aquarium filter compressors

The principle of operation of air aquarium compressors is quite simple. With the help of a special device, a mechanical injection of air takes place in the outlet opening to which a special hose is attached. This hose falls as low as possible into the aquarium and water is saturated with oxygen. Most often, a special sprayer is attached to the end of the Schlag, which breaks up the air stream into many tiny bubbles, which allows the aeration process to be carried out much faster. Aeration is called the supply of air into the water mass, so aquarium compressors are often also called aerators.

Depending on the air injection mechanism, there are two main types of aquarium compressors: membrane and piston. In membrane oxygen supply to the air occurs due to the movement of special membranes. This is a great option for a silent aquarium compressor, so it can be turned on all the time, even at night. Such an air pump will not interfere with the rest of the people in the room. But such devices have their disadvantages. So, such a quiet aquarium compressor does not have enough power to conduct aeration of very large tanks with water or aquarium columns. However, for home aquariums it is usually quite enough (the largest volume of water in which a membrane compressor can work is 150 liters).

The second type of aquarium compressor operates on the basis of the movement of the piston, which forcefully pushes the water jet into the hose. With this mechanism, you can create even very powerful aquarium compressors that can handle large volumes of water. Most often they are used in aquariums located in public places and having a large size. Aquarium columns are also often supplied with a similar compressor. The disadvantage of this mechanism is an increased noise level compared to the membrane variant.

Installation and use of the compressor

Most often the air compressor should be located above the water level. Therefore, its external unit can be put on the shelf next to the aquarium or directly on its cover. There are also options with vacuum suckers, which are easily fixed to the walls of the aquarium from the inside or outside. Depending on the design features, the aerator can operate from an electrical outlet, or from batteries. After installation, the pump tube is lowered as low as possible into the aquarium, it is advisable to place it on the bottom (some owners, guided by aesthetic considerations, bury sprayers in the ground, although this is not recommended).

If we talk about the mode of operation of the aerator, then in the case of silent mechanisms, most aquarium owners leave them to work all the time, since this device does not consume much energy. Meanwhile, some owners believe that it is more useful to periodically turn on the aquarium compressor (the optimal mode is two hours of work and two hours of rest). In addition, it is recommended to constantly turn on the aerator after feeding the fish, as well as at night. In this case, the aquarium will be best enriched with oxygen, and the putrefactive processes caused by the products of the vital activity of fish and food debris will slow down.

How much time a compressor should work for the aquarium?

Konstantin Bogdanov

Depends on the population of the aquarium and its population of fish and plants. If the aquarium is normally populated with plants and fish are present in a small amount, then it is not at all necessary to aerate the water around the clock.
It can determine the compressor running time. Turn off the compressor and watch the behavior of the fish, if the fish begin to rise in the upper layers of the aquarium, and even more so grab air from the surface, immediately turn on the compressor. Judging by this data, make a conclusion about the compressor operation time.
If you have a filter with aeration function, it is better not to turn it off completely. It's easier for many reasons.
At night, it is highly desirable not to turn off the compressor. Although oxygen consumption by sleeping fish falls (however, there are night species), nevertheless, at night, plants emit carbon dioxide instead of oxygen. So without aeration in the aquarium, the densely planted fish have a great chance not to live until morning with the aeration turned off.
As a rule, beginners, ugly over-populate their aquariums and prefer to squeeze plastic Chinese garbage into aquariums instead of live plants, so I usually strongly recommend beginners to not turn off the compressor or filter at all.

Natalia A.

If you have a filter with aeration 2 in one 24 hours a day, turn off only for flushing as it gets dirty, if the compressor is separate, then you need to have the detailing — is there any living plants, is the density of fish landing.

How often do you need to turn on the compressor in the aquarium? And very quickly the water began to smell. Partially changed did not help


The filter must be on all the time. It is necessary to switch off only at the time of feeding (it is impossible to overfeed, the rest of the food will rot). And wash it more often. If the filter will work constantly, but it will not be washed, naturally there will be a smell. But the replacement of water is not worth it. The aquarium forms its own microflora. Changing the water you only break it, because of this, you can also smell, fish and plants can get sick. If you change the water too much and often, then the fish can die. It is only necessary to add the amount of water that has evaporated.


Аэрация должна быть, по идее, постоянно. Все зависит от того, какие и сколько растений в акве. Но главное, запах не от недостатка воздуха, а от недостатка фильтрации. Чем мощней фильтрация, тем лучше. Перефильтровать воду нельзя, а вот недофильтровать…

А сколько часов в сутки должен работать в аквариуме фильтр-компрессор?


а я купил себе реле времени и выставил программу-час работы-час отдыха днем. Ночью полтора часа работает, полчаса отдыхает. For a day I was following the oxygen content in the aquarium and was able to pick up such a regime. Look, if the fish are just beginning (Watch carefully! DO NOT allow oxygen starvation!) To move closer to the surface (but not to eat or for some other obvious reason), then turn on aeration. Constantly keep the compressor turned ON-NOT! it's a constant vibration, and it is very harmful! A 24-hour compressor can only be turned on in one case — if the filter is external, that is, the vibration is not transmitted to the aquarium. It is recommended to install a non-return valve even before a conventional sprayer to reduce noise.
This heater with a thermostat should be turned on all the time, but the compressor only as needed! Ideally, you should NOT have any equipment at all in an aquarium!
It is better not to overpower the aquarium and find the right balance between the number of plants and fish, as well as observe the length of the daylight hours.

Elena Gabrielyan

The filter with the aerator should work continuously without shutting down (24 hours a day) and switch off only during the flushing time. It is also necessary to take into account the starting time of the equipment - constant switching on - turning off quickly leads to the fact that the equipment will burn.

Does an aquarium compressor always work?

Sergey Tyunin

"The compressor for the aquarium is an important device designed to aerate the water in the aquarium. It is through aeration that all the inhabitants of this confined space are supplied with oxygen.
In addition to aeration with the help of a compressor for the aquarium, two more equally important tasks are performed:
The bacterial film that forms on the surface is destroyed.
Equalized water temperature throughout the aquarium volume. "
Whether the compressor should work continuously or not depends on the volume of the aquarium and the number of inhabitants, as well as their characteristics. For example, for one unpretentious fish living in a 3-liter aquarium, the compressor is generally optional. If the population density of the aquarium is high or there are individuals among its inhabitants that are demanding of conditions, then it is not recommended to turn off the compressor.

How much should a compressor work in an aquarium? Or is oxygen supplied metered?

Aleksey komishan

In general, the compressor should work constantly, create a stream of water, if there is no filter that would mix the water layers in the aquarium, and the bigger the aquarium the more intensively it should be done, otherwise the water in the aquarium will quickly turn sour from fish feces, and more often it will be necessary to change the water. And so that the compressor does not interfere with sleep - because it cracks, it must be put on a porous rubber - a thing!

Alla Kopylova

Well, I do not know))) I have 6 akvasov. Plants are alive and not artificial, there is no filter at all, because there is no need for it. There is a CO2 system. Air is supplied only at night (when the lights are off), because during the day, the air emit plants)))
The water does not turn sour, because all the ficals process the plants (natural fertilizer), I make a substitution only under the condition of weeding the aquarium.
By the way, if you're interested, we do the weeding often enough. So, if you need plants - please contact)))

How many hours should the compressor work in the aquarium?

Natalia A.

It all depends on what kind of fish is in the aquarium and what kind of stuffing, for example, for discus or crucian carpentry 24 hours a day, for other types of fish, you can do without it if you have aquatic vegetation and a loose planting fish. on what kind of fish and what should work in aqua all 24 hours, I mean around the clock.


always, otherwise when you turn off at night there is a chance to find dead fish. but it all depends on the fish. There are those to whom the presence of aeration is not necessary (labyrinths, lungfish, intestinal breathing catfish). All representatives of this species swallow air from the surface. guppes, pecilia, mollies, swordtails are quite capable of living without aeration, if the aquarium is spacious enough. cichlids and gold aeration is required, otherwise they will die. small fish such as tetra, neon, danios and similar things can do without aeration, if the aquarium is spacious and not overpopulated

Can I turn off the compressor in the aquarium? And how long will it not hurt the fish? Thanks in advance


it all depends on the quantitative and qualitative fish population as well as vegetation in the aquarium ...
I dare to suggest that you are a beginner aquatic amateur ... so you probably have a lot of fish and little vegetation ... in this case, aeration is simply necessary ... another question is how is it done ?? because having an internal filter with a nozzle for aeration, you can not worry about additional oxygen at night ... and if the noise of the bubbles prevents you from sleeping, it is enough to let the output stream of the filter (with the air hose disconnected) along the surface of the water (below its level)
questions remained ?? ? Refer to the aquarium community "Aquarium home" // here will always help and prompt

Tatiana popova

I turn it off at night every day because it hums and interferes with sleep. Moreover, I can forget to include a day, and two, and three. Nobody died. They even breed. Barbushiha, swept away, spawn. I can not even imagine what this should be in the aquarium so that the fish in it so easily suffocated. Oxygen not only through the compressor enters the water. It is still emitted by aquatic plants and some amount dissolves from the water surface from the air. Constant oxygen starvation, of course, is harmful to fish. They will eventually wither, ache and begin to breathe. But do not bring the situation to the point of absurdity. A day, or even a few days, will survive. In addition, you need to consider how many fish in how many liters of water live and what breed these fish are. For example, the resilient to the incredible guppies in a spacious aquarium often do not need a compressor. In any case, back in Soviet times, I didn’t have a compressor at all, and guppies and swordtails lived. And they bred very abundantly.

Elena Gabrielyan

It is desirable not to turn off the air to the fish. Otherwise, at night, oxygen is consumed both by fish and plants, and if there is a shortage of it, your wards will suffer from oxygen starvation, which can lead to disease and death of the fish. The filter is now produced 2 in one. that is, it filters water and at the same time enriches it with oxygen. Equipment should work 24 hours a day. And even from the constant switching off of the switch off, the motor clock at the compressor and the filter coil very quickly burn out.

Olga Taranina

In no event it is impossible to turn off the compressor for the night, since at night not only fish but also plants absorb oxygen. So fishes like gourami, cockerels and other labyrinths don't care, you give air to the aquarium or not, as they breathe atmospheric air. And such fish as angelfish, two or three hours of oxygen starvation are enough to die - they will not live a night without air supply. To prevent the compressor from interfering at night, take it to the corridor - the hose length does not affect the performance! Hose of the desired length can be purchased at the car market or in stores.

svetik korolchuk

And I don’t turn it off at all, but in order not to interfere for the night - I put the compressor in a jar and covered it with a lid, after cutting holes for the tubes and the switch, then I overlaid it with cotton wool and voila the noise DOES NOT SHOCK ONLY.

I bought an aquarium and fish. I do not know how intensively the compressor should work

Pan Sigismund

1. Air does not happen much. Just the compressor under the volume of the aquarium is selected.
I have three of them in general and they all pump. Fish have not complained yet)))
2. It is better to remove the lamp, because a) water from the light blooms; b) water is heated, which is critical for fish; c) ample daylight.
3. At night, the fish doze. This is completely normal.


Wow! In 17 liters 19 fish! Is there water left? Pieces of 5 medium-sized fish are enough. For one scalar one needs 50 liters! Leave only guppies, everything will be OK! The compressor should work constantly, but not too hard, so that the fish do not wind on the aquarium!

Kondraty Parishes

Fish scribe ...
Aquarium (in fact, this is an otsadnik for fry) clean. In its place put at least a 50-liter (so as not to throw out the filter), and leave the fish the same. Angelfish in such a volume (17l) will not survive.
This “aquarium” can be used as a shrimper or for a dozen guppies or neons, but it will bring immeasurably more hemorrhoids than a can of 100 liters, because it is very difficult to establish the biological balance in this glass, and it is easier to break it! What has already been done by so many illiterately selected fish.
And the fact that the water is turbid is not scary in the first few days ...

How much time per day should be included oxygen in the aquarium?


Do not harm your fish! Do not over-oxygenate the water!
Enough a few hours a day!
Let us think: in nature, does anyone give air to the fish "always" ??? Round the clock air is received only by fish living near waterfalls. These waterfalls and perform the role of a natural copressor. And in nature, the fish get the air produced by aquatic plants. That is, the plants in the aquarium also do not interfere ... :)


Excess oxygen is harmful to fish and plants.
Plants begin to wither and turn yellow.
Generally guided by the fish. If they float near the surface and swallow air, it means that there is little oxygen in the water and you need to either turn on the compressor or think about lighting, because with good lighting, the plants quite actively produce oxygen, which can be seen even in plants when from broken-down stems there are bubbles.

Catherine Shavergina

It seems to me that in order to re-oxygenate the normal separated water, the compressor must supply microscopic air bubbles. Therefore, it is unlikely to happen. But the fact that at night the plants also consume some amount of oxygen must be taken into account. Therefore, I usually leave the aquarium without air for the night.
