How often to turn on the compressor 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.

Silent aquarium compressor: how to select and install

Small-sized aquarium compressor is an essential accessory for keeping ornamental fish at home. His choice and proper installation will provide the necessary conditions for the life of aquatic fauna and flora. Manufacturers offer different types of compressors, and therefore there is the problem of choosing the optimal type of device. Let's try to figure it out.

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.

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.

Types of compressors

Aquarium microcompressors in their device are divided into two main groups: membrane and piston.

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.

Choice Questions

Aquarium equipment manufacturers produce a wide variety of low-noise aerators.

Schego Compressors

First of all, it should be noted the products of the German company Schego, which produces compressors for home aquariums and columns of virtually any capacity.

So, for a small 70-liter aquarium, a small-sized Schego Prima aerator with a capacity of 100 liters per hour and a power of 3 watts is suitable.

But for a decorative large-capacity water column, you can purchase a Schego W53M noiseless compressor with a capacity of 350 liters per hour and a capacity of 5 watts. It provides air to a depth of 5 meters.

Chinese Triton Aerator

One of the most common models of silent microcompressors. It has two aeration channels with a power of 2.9 W, which ensures reliable circulation of air and water in an aquarium with a capacity of up to 170 liters.

Equipment from Collar

Very convenient small-sized silent aerators are produced by the Ukrainian company Collar. The aPUMP compressor of this manufacturer is considered one of the most silent in the world. With a power of only 1.5 W, it provides reliable aeration of the aquatic environment in a 100-liter aquarium at a depth of 80 centimeters.

These examples show that when choosing a silent compressor you need to proceed from

  • the size of the aquarium
  • power consumption of the device,
  • as well as the required depth of air supply.

Install silent compressor correctly

Silent aquarium compressor installation is quite simple. The external aerator must be placed on the shelf or directly on the glass cover of the aquarium so that the length of the hose allows for aeration from the bottom up.

That is, the end of the spray hose (if any) was as close as possible to the bottom of the tank. Sprayer is advised to use to ensure that air bubbles are as small as possible. In this case, the process of enriching the aquatic environment with oxygen is more intensive.

Some models of household silent compressors for an aquarium are supplied with suckers. This is very convenient, as the aerator can be securely attached directly to the glass wall of the fish house. Of course, you must have a nearby power source (sockets).

How to use aquarium compressor?

There are several opinions when it is necessary to conduct aeration of water. Some aquarists silent compressor runs continuously without shutdown. Although the power consumption of the aerator is quite small, many owners of ornamental fish use the device on schedule: 2 hours of work, 2 hours break.

It is also advised to conduct aeration of water at night, with minimal illumination.

The choice of silent compressors for aquariums is quite wide, and it is quite possible to purchase the most silent aerator. In this case, a quiet life will be ensured for both the fish and their owners.

Install the compressor 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.

Compressors belong to the main equipment, as well as filters, water heaters, lamps. What kind of compressor is needed for an aquarium depends on the size of the "pond" - the larger the volume of the aquarium, the greater must be the capacity of the compressor. The compressor aerates the water, i.e., 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. Compressors 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 compressor improves the circulation of water, thereby equalizing the temperature in different zones. How to install a compressor in an aquarium

It is recommended to install the compressor so that it is above the water level and outside the aquarium. If it is not possible to install the compressor above the water level, you need to additionally equip the device with a check valve. The check valve prevents the flow of water in the opposite direction - after all, the compressor 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 from the bottom, he must take care that the water does not flow out of the aquarium through the compressor in case of a breakdown or power failure.

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.


Aeration should be, in theory, constantly. It all depends on what and how many plants in aqua. But most importantly, the smell is not from a lack of air, but from a lack of filtration. The more powerful the filtering, the better. It is impossible to re-filter the water, but to mis-filter it ...

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

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 disconnect air to small fishes. 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.

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.

Noise from the aquarium compressor: (

It is impossible, moreover, you did not write the displacement and parameters of water. you need to buy a compressor silently - it is inexpensive, just not China (they all make noise), you can buy a more powerful one and buy a pipe to it. to put in a more distant place (balcony, kitchen, another room)

Anzhela shein

If the compressor is noisy, maybe some small particle got into the tube, wash it well, it is not advisable to turn it off, because it gives air to the fish, I turned it off for the night, two fish died in the morning

Russian roulette

Oh dear mother ... you have 10 fish in a 16 liter aquarium?)))))))))))))))))))))))) you are overpopulated))) and even a sufficient number of living plants will not save ... you definitely need an aerator !!!!)))
and the compressor can be turned off at night)))

Dear people with tumbling compressors, everything is done like this: A system is bought in a pharmacy (drip in common), a tube with a power regulator is cut off from it, one end is attached to the compressor by a rubber seal from the same dropper, a spreader is put on the other air, adjust the air so that the compressor does not hum. It is not recommended to turn off the compressor for the night (the filter for your volume can be purchased for 200-300r) Regarding distilled water: you can add at least every day at the rate of no more than 20% of the volume of the liquid, of course, there are too many fish in your volume.

Leonid Zaychik

so that the compressor does not make noise: turn on the diode (D7, D226) in the power circuit, reduce the power, and hence the noise 2 times. place the compressor in a foam plastic box lined with felt or cotton, buy an air flow regulator at any pet store, squeeze (not completely) the compressor tube with a clothespin, buy plants: valesneria (plant), helode (can live in the water column) (floating) fish you are not large, worry about the overpopulation of the aquarium is not worth it, but you do not have to sit down the new ones either. settled water (2-3 days) should be changed at least every day (1-2 liters), but this is kanitelno, so it’s better once a week --- 30%. feed the fish 1-2 times a day, do not overfeed! ! food --- flakes (for example, "Vipan"), frozen bloodworm, dried daphnia. In the summer you can catch a living: Daphnia, the Tubber, Coret. remove feed residues after 6-8 minutes. it is undesirable to switch off the compressor for the night. maintain the water temperature within 23-25 ​​degrees. there will be some questions, write in a personal, happy to answer. good luck !!!!
