Silent aquarium compressor: how to select and install

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.

Before you populate the fish in the aquarium, you must purchase the necessary equipment for it. This is a lighting and water filtration system, a device for thermoregulation and a pump.

An important role in ensuring the normal functioning of the aquarium is played by aeration, that is, blowing air through the water column, which contributes to proper gas exchange in the tank. At the same time, the air, passing under pressure through the water, splits into many tiny bubbles. From the bubbles in the water and oxygen enters.

Aeration is more effective than smaller air bubbles, since in this case the area of ​​their contact with water is much larger.

Aeration contributes to the mixing of water layers, and hence the equalization of the water temperature in the aquarium. In addition, bubbles destroy the film, which can form on the surface of still water and interfere with the normal gas exchange.

In addition, the aquarium with rising bubbles and lights looks very decorative.

For successful aeration use such a device as an aquarium compressor or an air pump, as it is also called. On sale there are many options for aquarium compressors, but many of them have a significant drawback: they are very noisy.

And if you consider that the device should be turned on all the time, day and night, then the life of people in the room with an aquarium cannot be called comfortable.

The best way out would be to purchase a silent compressor for the aquarium. Let’s find out how to choose a silent compressor for the aquarium, and which one is suitable for your house for fish.

It should be noted that the concept of noiseless with respect to aquarium compressors is a bit incorrect. It is more correct to call them quiet, since any of these air pumps produce a certain level of noise during operation.

There are two types of aquarium compressors. In a piston aerator, air is pushed out by a piston.

This unit is characterized by high performance, durability, but the noise level in it is quite high. The second type of aquarium compressors – membrane. The air in it is supplied through membranes, working only in one direction.

Such an aquarium air compressor is relatively silent and consumes little power. But its power will not be enough for a large aquarium.

The choice of a silent compressor for an aquarium depends on the size of the tank with water, as well as on the required depth of air supply. Experts advise when choosing an aquarium compressor to take into account such a calculation: the aerator should have a capacity of about half a liter of air per hour, designed for one liter of water.

For smaller aquariums, the compressor is considered one of the most silent ones. JBL ProSilent a100, which has a built-in silencer, so its work does not prevent people from resting in the room. This diaphragm compressor comes with a check valve, a spray bottle and a two-meter hose.

Popular silent model of the compressor is the aerator of the Chinese company Triton. This two-channel aerator can provide reliable circulation of water and air in an aquarium with a capacity of up to 170 liters.

Another silent compressor manufacturer is a German company. Eheim – together with the aerator offers high-quality sprayers and hoses.

Ukrainian company Collar produces small and easy-to-use silent compressors of the brand. aPUMP. This aerator is able to work successfully in a stitle tank at a depth of 80 cm.

If you could not buy a compressor that would suit you in terms of noise level, you can make such a silent aerator yourself.


Also compressors are adjustable and not adjustable.

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.

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 compressor power depends on the diffuser.

The smaller the holes, the more pressure must be created by the compressor.

Compressor care, preventative maintenance

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.

How to reduce compressor noise :: how to make a silent compressor for an aquarium :: Equipment and accessories

Very many people set up aquariums at home. It has been scientifically proven that the process of treating fish swimming in an aquarium noticeably calms and relaxes after a hard day’s work. And the fish are the least allergenic type of pets.

Any aquarium requires the installation of a compressor that is responsible for saturating water with oxygen. And then there is a problem – the compressor makes too much noise in complete silence.

  • – instruments;
  • – foam rubber;
  • – Styrofoam;
  • – sponge for washing dishes.

1. When buying accessories for your tank pay attention to the compressor. Before going to the store read the special literature on how to usually pick up the necessary parts for the aquarium.

When you come to the store, carefully listen to everything that the sales assistant will tell you. Currently, there are many noiseless compressors on the market that operate almost inaudibly.

It is not difficult to guess that such compressors will cost a little more than ordinary ones. However, even silent models can make a little noise, which causes some discomfort.

2. If you have a compressor with a simple type of device, then try to disassemble it. To do this, study the manual. In it you will find the location of all connections and fixtures.

Remove the screws and open the case. Carefully examine how the internal parts are relative to each other. The most common cause of characteristic cod is the friction of the membrane on any protruding part.

Find her. It is necessary to either carefully file or cut out a place that prevents the membrane from moving silently.

Do all the procedures very carefully, using a special tool, so as not to damage the other parts.

3. To reduce the sound of the compressor running, you can try to install it on a special stand. It must be made of a material that absorbs vibrations, because the noise is caused by frequent vibrations of the membrane inside the compressor. Try to put the usual sponge for washing dishes.

The thicker it is, the quieter the sound will be. You can also put the compressor in a small soundproof box. If not, use foam or foam.

Wrap the compressor case with it and secure the material with rubber bands.

4. It is worth noting that many compressors after some time of operation begin to pop. This can be caused either by clogging or loosening of some internal parts.

Disassemble the compressor, find the parts that were loose and fix them.
