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.


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

.The main requirements that must be placed on the device when choosing it

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.

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.

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.

The choice of compressor is based on several criteria:

  1. Noiselessness Often the aquarium is placed in the bedroom where people relax. Given this fact, it is best to buy a silent compressor, because this device must be switched on all the time. To reduce noise, the unit can be removed in the cabinet. However, in this case, you need a fairly long duct. The best option is to purchase an air compressor for the aquarium, it is he who is considered the quietest.
  2. Existence of smooth adjustment of a stream of air. If you can change the speed and force of the air supply, you can easily adjust the aerator for a different number of nozzles and filters.
  3. Compressor power. Optimum performance can be calculated by the formula: 0.5 l / h per 1 liter of water. It is clear that the power depends on the volume of the aquarium. For capacities from 100 liters, which are considered large, it is recommended to use piston compressors with low-voltage power. During a power outage, such equipment for the aquarium can be connected to a car battery.

The compressor will saturate the water with oxygen – this process is called aeration. In their choice aquarists follow simple rules.

First, the aquarium compressor should be as quiet as possible. The design feature of compressors is that they all make noise during operation.

Absolutely silent compressors have not yet been invented, so you have to choose those models that introduce less discomfort at permissible power. Hence the second rule – the compressor must cope with the saturation of water with oxygen – the larger the aquarium, the more powerful the compressor will be needed.
