An aquarium compressor is a device that supplies air to the water to enrich it with oxygen. Often the lack of air happens because the water temperature is too high. This situation can lead to the death of fish, so additional air supply devices are used. In order not to spend money, you can make a compressor for an aquarium with your own hands. This process does not cause any particular difficulties and does not require special skills.

You can make your own compressor

Manufacturing process

There are many ways to make a compressor, but the simplest ones are worth highlighting. The first version of the do-it-yourself fish compressor is as follows:

We need to find a small electric motor. Connect to power supply. Desirable engine power - no more than 12 volts. Energy costs will be minimal. It also allows you to make a battery-powered compressor for an aquarium with your own hands. Relevant for frequent or prolonged power outages, as well as when moving.
It is necessary to attach an eccentric to the engine, on which the pump is attached. The eccentric moves the pump, and it circulates the water. This allows you to enrich the water in the aquarium with oxygen.

In this video you will learn how to make a compressor:

This option is silent. It does not interfere and does not disturb during sleep. If sound is not a problem, then you can make an aquarium compressor with your own hands in another version:

Buy an electromagnet. Frequency from 50 Hz, which operates from 220 volts.
Attach a pump to it. When the magnet is turned on, the pump membrane will begin to move at the same frequency with which the electromagnet operates. This allows you to pump air into the pump, and then into the aquarium.

The work of the magnet creates a certain noise. This may cause inconvenience.
Do not forget to purchase the necessary material
Often aquariums are installed in places where a large number of people accumulate. In order for the microclimate to remain optimal, the operation of the compressor must be constantly maintained. If an electromagnet was provided during the manufacture of the device, then the compressor should be hidden so that noise does not interfere. You can hide in a pipe that will pass under the aquarium. You have to buy an air duct. It is needed to transfer air to the aquarium. This will allow the system to function optimally.
To avoid a strong shock wave from the engine, you need to create a protective level. And the noise of the device itself is perfectly compensated by a wooden box.

The compressor power should correspond to the volume of the aquarium. It is necessary that the air flow be soft and moderate. For this, the volume is calculated. Even for large engine volumes, 12 W will be enough.
If the air cooler is too powerful, then you can bring the aquarium inhabitants to illness or death. The high power motor will create strong water circulation. This will disrupt all the natural and life processes of fish. If there is a lot of algae in the aquarium, then the compressor should be turned off during the day. Otherwise, you can create an excess of oxygen.
Device placement
Making a mechanism is quite simple. First you need to choose a place to stay. You can place it inside the tank, above the surface, or outside. Spray hoses are placed at the bottom. It is not necessary to provide for fastening; you can press down the hose with a heavy stone or shell.
For the tube, it is better to choose silicone or any other elastic rubber. It is necessary that it easily endures deformations and does not crack. The lifetime of the device depends on this element.
The tube must be inert and not emit any harmful substances. under the influence of water. If there is no silicone, then it is better to buy it separately at the pet store. You can also use a drip hose.
Overview of popular models
Aqvel has been in existence for 33 years. She belongs to one of the best manufacturers. Characteristics of the OxyBoots AP - 100 plus model:
the volume of water that it can enrich with oxygen in one hour is 100 liters;
is established on aquariums up to 100 liters;
consumes 2.5 watts per hour;
small size.

The main disadvantage is that there is no way to regulate the flow force. But this is not necessary for small tanks.

The inability to regulate the current strength is a serious minus
DoFhin on Russian market appeared in 2008. The products produced are of high quality and are in great demand. Among the most popular models, the AP1301 device can be distinguished:
consumes 1.8 W of electricity;
used for aquariums up to 125 liters;
works almost silently;
volume of water enrichment - 96 liters per hour.

The main drawback is incomplete equipment. Sprayer and hose must be purchased separately.
An aquarium compressor is an indispensable device. It provides full life fish. It is worth remembering this, paying special attention to the choice and creation of the product.

All fish lovers know that in order for the water kingdom to please the owner, it must be properly looked after. One of the components of proper care is the compressor. Consider what function it has and how to choose it correctly.

Why do you need and how long should the compressor work in the aquarium

Aquarium fish for a full life need optimal conditions existence. They need constant oxygen, but sometimes the water surface and the number of plants inside is not enough. In this case, you need to purchase an additional device that will help saturate the water with oxygen - this function is performed by the compressor.

It is used to solve the following tasks:

Security. Rising oxygen bubbles saturate the water with oxygen.
Water mixing. Even a slight bubbling equalizes the temperature of the water at all levels. In addition, liquid stagnation is not allowed.
No film formation at the water's edge. Similar problems arise due to bacteria and dust.
flow simulation. This allows you to create conditions close to natural.

Such a device is important not only for large aquariums, but also for small ones, but the power should be different. The compressor does not have to run constantly, it is enough to turn it on for a while twice a day. If the ambient temperature is high, then it is recommended to do this more often, since oxygen is consumed faster when the water is heated.

How an aquarium compressor works

An aquarium compressor is a device that is designed to enrich the water with oxygen.
The principle of operation of this device is as follows:

Through the tubes, which are located at one end above the water, and the other is attached to a pump located at the bottom of the aquarium, oxygen enters. The air pressure is regulated by valves and clamps.
The upper part of the pump is an atomizer made of an abrasive substance through which the aquarium is aerated by the formation of a large number of bubbles.
The bubbles burst on the surface of the water and thus destroy the bacterial film, moreover, during the movement they mix the layers of water.

Important! The smaller the bubbles, the larger their area of action.

Varieties

The main classification divides compressors for aquariums into the following groups: membrane, piston and pumps. They differ in the principle of operation, the strength of the noise and the price.

Piston

The principle of operation is the movement of the piston, with the help of which air is pushed out. The rotational movements of the piston shaft become oscillatory. Such changes help to achieve the desired air supply power. This is the ideal compressor for a bedroom aquarium as it produces minimal noise but is more expensive than a diaphragm compressor.
The pros are:

durability;
almost silent operation;
high performance;
can be used for large aquariums.

high energy costs;
great cost.

Membrane

The principle of operation is the movement of air from a chamber connected to the membrane due to pressure drops, which are created due to the oscillations of the magnet.
Pros of this device:

low energy consumption;
easy repair;
cheapness.

The disadvantages of these devices are as follows:

low power;
loud noise during operation.

Manufacturing instructions

Cut off the cap of a plastic bottle with a neck. We remove bumps and a plastic strip. We unscrew the cap from a piece of the bottle.
Cut out the round part of the ball and divide it in half.
We fix one part of the ball with rubber bands on the neck of the bottle. We stretch the ball well and cut off the excess that protrudes more than 2 mm from the elastic.
On the covers we outline two places in the form of a socket and use a soldering iron to make holes. We clean up the bumps.
From the remains of the balls, we cut out strips 0.5x1 cm in size. We glue them with glue to the lids on one side of the hole. At the same time, we glue one strip on the outside of the lid near one hole (this will be the exhaust valve), and the other inside the lid is already near the other hole.
At the syringe, cut off the edge where the needle is attached, and glue it to the outlet valve using hot glue.
We connect the lids and necks together - these will be mini-compressor chambers.
We glue mini-cameras on the base, two from each edge. In the center of the base we glue the bottle cap with the hole down.
We cut out two circles with a diameter of 2 cm from plastic. On one side we make a hole and push the straightened paperclip in half. We fix the second part with glue to the circle.
We take a gearbox with an engine and glue circles with paper clips on the side ledges. We apply a large amount of glue to fix the circles as much as possible.
We connect the gearbox with a cover that was fixed in the middle of the base.
Cut the cotton swab into 4 parts. Align the paperclip and create an eye on one end. Insert a piece of cotton swab into the ear. Then we wind a thread on it and soak it with super glue.
We put the ear on the gearbox, measure the distance to the free cover. Before removing the excess, we bend the edge, glue it to a small piece of plastic. After everything has frozen, we connect it with a mini-compressor.
After attaching all the paper clips to the gearbox, we bend the end on the drive for fastening.
Solder the wires to the motor. We glue the battery, the switch and solder the wires.
From the part of the dropper we make a connection for 4 tubes, which we pre-cut. To do this, we make holes in the container using a soldering iron.
We connect one end of the tube with the edge of the syringe, and put the other into the dropper. We fix them with hot glue and glue the dropper to the base near the battery. The mini compressor is ready.

How to choose

There are many types of aquarium compressors on the market today. In order not to be mistaken, you need to know what to look for during the purchase:

Performance. This indicator shows the amount of air that the device distills over a certain period of time. Productivity directly depends on the number of fish and their species. The optimal indicator is 0.6 l / hour per liter of water. To increase this figure, a biofilter must be present in the tank.
Power. Determines performance and the largest number energy required for the proper operation of the device. This indicator indicates the maximum allowed immersion depth of the device. The most widely used devices with a power of 3-10 watts.
Aquarium size. The compressor should be selected based on the size of the tank where the fish will live. The smaller the aquarium, the more compact the compressor should be.
Manufacturer. Customer reviews point to the popularity of DMs with high power, which is also amenable to regulation. Also popular are Italian fixtures, which are also not very noisy.

How to install a compressor in an aquarium

Important is correct installation device. The first thing to do is to decide where the compressor will be located. It can be placed above the water surface or in a tank placed outside the aquarium. Submersible compressors must be installed in such a way that there are no problems with cleaning, which must be carried out from time to time. In order not to create a lot of noise, foam rubber or polystyrene is laid on the bottom. The tube is pressed with a shell or a pebble.

Important! To prevent the water from the thermostat from overheating, a compressor is installed near this device, which will mix the water.

Compressor care

In order for the compressor to work the most time, it needs systematic care, which consists in the following manipulations:

replacement of air filters;
monitoring the condition of rubber membranes;
regular cleaning of diffusers;
check the condition of the air hoses.

Possible problems during operation

Despite the advantages, these devices can have the following problems when working:

Increased noise during operation. Occurs when the valves are dirty. This reduces the power of the device. If even minimal manifestations of atypical noises occur, the device must be disassembled and cleaned or taken to a service.
Membrane damage. This problem leads to increased noise and water aeration problems. In this case, a replacement part will be required.
Filter problems. The reasons can be different - from problems with the power supply to the destruction of the rotor due to mechanical damage. All this requires repair with the replacement of damaged parts.

To avoid these and other problems with the aquarium, it is better to entrust the care of it to professionals who can identify the problem at the beginning and fix the situation with minimal expenses. Now you can easily choose the right compressor that will meet all your needs without any problems, and if you really want to, you can even make it yourself.

The compressor for an aquarium is one of its main components. It saturates the water with oxygen, which is so necessary for the life of the entire ecosystem in the aquarium. Often this device acts as an aerator and is one of the first purchases of a novice aquarist.

Each compressor has its own distinctive features, which is important to know when choosing it in the store. Only when the choice is made correctly, the fish and plants in the aquarium will feel comfortable, receiving the necessary amount of oxygen.

Despite the fact that the aquarium is only a small semblance of a real reservoir, it needs no less oxygen saturation. For this purpose, plants are planted in the aquarium soil. But even they are not always able to provide the fish with the proper oxygen content.

Therefore, a compressor should be used, the main task of which is to saturate the water with oxygen. This kind of device, under some pressure into the water, releases small air bubbles, which begin to rise upward, thereby mixing it well.

Also, without a compressor, the water temperature will not be evenly distributed throughout the aquarium. And it is thanks to its presence that the water airlift filter will function optimally. Therefore, the compressor can be safely called an important and irreplaceable device.

rich variety

Now that we know about the important functions of the compressor, it becomes clear that its choice should be approached with all responsibility. AT modern world manufacturers offer a wide variety of compressors to choose from. All of them can be divided into several main types:

with vibrating or piston design;
working autonomously (on batteries) or from electricity;
with small (internal) or large (external) power.

It should be noted that high-power compressors produce quite a lot of noise, but provide the maximum enrichment of water with oxygen.

Right choice

Today, there are several leading criteria that you can rely on when choosing an aquarium compressor.

These include:

The presence of the function of regulating the flow of air.
When the compressor functions allow you to change the speed of the air flow and its strength, then they can be adjusted depending on what type of filter and model of atomizer is installed in the aquarium.
Power.
It is determined in relation to the volume of water in the aquarium using the following formula: for 1 liter of aquarium water 0.5 liters per hour. With a large capacity of the aquarium, it is recommended to purchase a low-voltage piston compressor, in the presence of which the filter will also work as efficiently as possible.
Noise level.
It has great importance when the installation of an aquarium is planned in the children's room. In this case, it is worth buying air compressor for aquarium. It has minimal noise levels.

After the compressor is selected, the next step is to install it correctly.

Installation process

During the installation of any of the aquarium compressors, several rules should be followed. First you need to determine the place where it will be located. It can be both the aquarium itself and a certain space around it. It can also be placed in the water column or directly above it.

When installed directly in the water, it is intended to use centrifugal pumps that perform the functions of aeration.

Therefore, it is best to place them close to the heater. This will allow the heated water to mix immediately to provide the most comfortable microclimate for all the inhabitants of the aquarium. This will make the filter work much better.

In cases where the compressor for the aquarium is not the quietest, and the noise causes some inconvenience, you should resort to the following trick. It is necessary to install the device on any soft surface. You can use foam or foam rubber. In this way, noise reduction can be achieved several times.

Another important factor is the regular cleaning of the compressor. When it is produced in a timely manner, it will not only work long time but it won't make a lot of noise either. It is enough to follow the listed rules so that the compressor copes with all its functions with a bang.

Do it yourself

Do-it-yourself compressor for an aquarium is a very real thing. It can be collected by following the basic principle, according to which you first need to accumulate air and only then supply it to the aquarium gradually. When the essence of the work becomes clear, you should familiarize yourself with how to make a compressor for an aquarium.

To get started you will need:

rubber chamber (as an air accumulator);
pump (can be taken from a bicycle or car);
tee (in the form of a three-code tap);
plastic tube (can be taken from a medical dropper).

Then you need to take two tubes from the tee, which will follow to the pump and chamber. Another one will serve as the output hose. For this purpose, you will need that part of the dropper tube that has a clamp. The end of this tube will need to be sealed with a cork, and a series of small holes should be made directly in front of it. They will let the air through.

In order for the air flow to begin to collect due to the tee, you must first open the line from the pump to the chamber and pump it to capacity, and then block access. Then you should open the direction from the chamber to the outlet hose. This will allow air to enter the aquarium. Your compressor will save the budget, but will have several disadvantages.

In order for the work process to take place gradually, it will be necessary to adjust the diameter of the tube using a clamp, which should be located closer to the tee. So, by trial and error, you can choose the most optimal air flow rate. Another tangible drawback is that the camera will need to be pumped up constantly.

Therefore, this structure cannot be left unattended for a long time. This also affects how the filter will function in the aquarium.

Correct use

Regardless of which compressor was chosen for the aquarium, there are several important rules on its use. Regardless of whether the device runs on batteries or mains, you can turn it on according to your schedule. Some aquarists do not turn it off at all, and some turn it off every two hours for a couple of hours of break.

In this regard, everything is strictly individual. But the compressor must be turned off after the fish have been fed. Also, the most suitable time for aeration is at night, when the lighting is at its lowest. Do not forget that you should regularly clean the device.

An electric or battery-powered compressor is an integral part of any aquarium. Its correct choice with subsequent competent installation will become a predetermining factor for the full and comfortable life of all aquarium inhabitants.

Many people, some of whom are even into aquarium hobbyists, do not quite understand what a compressor is. To them, it appears to be some incredibly complex machine built for industry. That is why when someone talks about creating an aquarium compressor with his own hands, this causes some bewilderment. Meanwhile, it is worth saying that in creating an aquarium compressor with your own hands, so that it pumps air into aquarium water with high quality, does not present much difficulty. In this article we will analyze how to make it and whether it is needed at all.

Everyone, even not big fans of aquarium fish, knows that these creatures breathe air, only in a special way, through the gills. They absorb water with oxygen dissolved in it, separate it from the liquid and absorb it. Therefore, if you don't have a lot of oxygen in your aquarium, your pet will not be very comfortable. And this is at best. At worst, he maybe even die.

While the compressor is a special item whose main task is to take air from environment and “squirt” it into the water where your fish is. AT wild nature the same happens, mainly due to the wind, which provokes a fairly strong movement of air currents, but after all, in your apartment you will not be able to constantly drive air, which is why you must install a compressor.

Types of compressors

Thousands of models and types of compressors have been manufactured by various engineers from many countries of the world, however, according to their structure, they are divided only into the two most extensive types:

Piston - very strong and sometimes able to conduct air in containers with water, up to two hundred liters. You definitely don’t have such volumes, besides, piston compressors are quite noisy, because every movement of the piston pumping air into water is accompanied by a very sharp, loud and unpleasant sound. Obviously, you probably don't need this type of compressor.
Membrane compressors are more compact, almost silent, although they cannot boast of such incredible efficiency as reciprocating ones. However, it will certainly be enough for you. They are divided, in turn, according to the type of installation into internal and external, as well as by power supply into battery-operated or from electrical network your house.

DIY manufacturing

In order not to get confused while creating a homemade compressor, you should know the basic principle by which it works. Its essence lies in the fact that first the device takes air into itself, and then, in small portions, injects it into your container of water. It is in the way it works that a hand-made compressor will differ from the one that was made in the factory.

The video shows one of the manufacturing options

How homemade compressor in general, it will pump air, because, in theory, it does not have any mechanisms to do this. Yes, this is, of course, true, but the same principle of operation will be used here as, for example, in a soccer ball or a car tire. Some people even use the ball to create a pseudo-compressor, but we will use a more clear, if slightly less simple, method.

So what do we would need:

a camera made of rubber (not the one on which they are filming or in which they sit, but the one into which air is pumped);
pedal hand pump, which are usually used for car or bicycle wheels;
three-way faucet (tee);
the so-called "system", that is, a thin tube made of bendable plastic, which is usually used to put droppers. It must be with a clamp.

Now take three tubes away from the tee. The first will go to the pump, the second to the ball or rubber bladder, and the third, made from a tube with a clamp, will become a hose from which air will exit into our aquarium.

Be sure to plug the end of the tube with a cork, and make several small holes in the tube itself (you can use a needle for this) so that air comes out of them. Also, pay close attention to the tightness of the entire structure. The air from it should come out only in those places that you have planned. You can also watch the video where various masters teach you how to make these devices.

The principle of operation of the created by your with my own hands the compressor will be quite curious: first, in order to collect the air we need so much, a tube will be used that leads from the pump to the chamber. Further, when all the air is collected and the chamber is filled to capacity, this tube stops working and the tube from the chamber to the outlet tube begins to function. In this case, the speed at which the air will go out is regulated by a special clamp. It is best to make the water exit as slow as possible, but in practice you will find out for yourself what speed should be ideal.

Well, in general, everything is ready. However, it is worth mentioning again that This compressor will not pump air into itself.. You need to pump air into the chamber about two or three times, and generally keep track of how much oxygen is left. This also opens up the next disadvantage, which is that you cannot leave your fish unattended for at least a couple of days if there is no one to pump air, naturally.

Another production option

Bonus: How to make a DIY aquarium cooler filter

To keep your aquarium clean, you just need to purchase or make your own aquarium filter.

With the purchase, you yourself will figure it out, but here's how to make a filter with your own hands - we'll figure it out here.

There is, of course, a huge number of filters, including homemade ones. But today we will analyze the simplest possible design, which you yourself can do in less than half an hour.

To do this, take the most ordinary bowl of clay, put a mixture of nylon threads and quartz sand into it, then install the most ordinary funnel into this bowl and insert a hose into it, from which air should come out, as shown in the figure below.

Another bonus: we make our own atomizer for the aquarium

The easiest way to make a sprayer you have already read above, when you had to pierce the hose by plugging its end.

This method is indeed extremely simple, but I do not guarantee its particular reliability. There is a slightly more complicated way, but it inspires a little more confidence.

For him, you need to get a porous stone and attach it to the hose. This may seem quite complicated, but if you use special silicone for fastening, you will definitely succeed.

And remember that when keeping even a few fish or aquatic plants, you'll need a compressor anyway if you don't want them to die slowly. Even if you don't really want to make your own, there is an underrated option to go to the store and buy these factory-made tools.
However, if you still decide to make a compressor for an aquarium with your own hands, a filter or a sprayer, you can be congratulated: despite all the inconveniences associated with it, such a mechanism, with proper handling, will work quite reliably and for a long time, delighting your fish with oxygen.

At the word “compressor”, many people immediately remember a complex technical device that supplies compressed air for the operation of a pneumatic hammer in road construction. That's why when it comes to self-manufacturing aquarium compressor, this causes some confusion. Meanwhile, to make a small device for forced air injection into aquarium water with your own hands is quite within the power of almost any person. But how to do it? And in general, why is it needed? Let's try to figure it out.

Being a device for creating pressure (compression), the unit supplies air directly to the aquarium environment. This process is very important for ornamental flora and especially fauna. Fish, as you know, breathe oxygen dissolved in water through gills. If there is little oxygen in it, then the very existence of pets will be in jeopardy.

In the wild, the same thing happens, only the enrichment of reservoirs with air occurs naturally: when blown by winds and as a result of fluctuations in the water mass.

At home artificial reservoir such air saturation is carried out with the help of - forced regulated supply of air flow to the aquarium water. Moreover, the smaller the air bubbles leaving the compressor, the more dissolved air is formed in the water space.

We can say this: the compressor is an ordinary air pump.

The main types of professional aquarium compressors

Manufacturers different countries have developed a wide variety of aquarium air pumps to suit any ornamental fish owner. Structurally, devices can be divided into 2 main types:

piston,
membrane.

Piston professional compressors are more powerful and designed for aeration in aquariums large capacity, over 200 liters, for example. At the same time, they are also the noisiest, since the movement of the piston is always accompanied by a fairly loud sound.

Membrane air pumps are almost silent, their operation is based on the movement of a rubber membrane that pumps air into the outlet tube.

Compressors also differ in the type of power source: either from a household electrical outlet or from batteries. There are also external and internal devices, if we consider the installation method.

Price range data technical devices is also quite wide - from several hundred to 20 thousand rubles (for example, the Italian Sicce MULTI pump), depending on the design, equipment, power and other characteristics.

If, and there is no pet store nearby, then for the first time a home-made air pump made at home will help save the situation.

factory compressor.

DIY aquarium compressor

Such a device can be assembled if you understand the basic principle: first you need to accumulate air in some way, and then gradually supply it to the aquarium. This is the fundamental difference between a home-made unit and commercial piston or diaphragm pumps powered by an electric motor.

But how can you store air? The answer suggests itself: in hot-air balloon, a car chamber, a soccer ball chamber, etc. By the way, it is an inflatable ball that some home craftsmen use in such cases.

So, in order to quickly and easily assemble an aquarium compressor, you need:

rubber chamber (like an air accumulator);
car (or bicycle) pedal or hand pump;
three-way faucet (tee);
plastic tube from a medical dropper with a clip.

Three tubes must be taken from the tee: the first - to hand pump, the second to the beach ball, and the third tube (dropper hose with clip) will be the outlet hose. The end of this hose must be firmly plugged with a cork, and in front of it, several small holes must be pierced in the tube, from which air will come out. Of course, all connections must be reliable and tight.

To collect air using a tee, the “pump-chamber” line is first opened. The chamber of the ball is very strong in itself, so you can pump it up to failure. Then this direction is blocked and the "camera-outlet tube" line is turned on. In order for the air to exit into the aquarium gradually, the diameter of the outlet tube is adjusted in one place with a clamp. Naturally, this clip should be outside the aquarium, closer to the tee. Empirically, the air flow rate is selected.

In principle, a homemade compressor is ready. The disadvantage of such a device is that the battery chamber must be periodically inflated. As a rule, for normal aeration of an aquarium with a capacity of up to 100 liters, such pumping should be done 2 times a day. Therefore, a homemade compressor cannot be left unattended for a long time.

Do-it-yourself aquarium sprayer

It has already been mentioned that a larger number of small air bubbles has the best effect on the degree of saturation of water with oxygen. This is achieved using the so-called atomizer, which can also be made independently. Special knowledge and skills are not needed here.

First way: use a short rubber tube that fits over the outlet hose. It is enough to pierce a lot of holes with a needle on all sides of the tube, firmly plug its free end - and the atomizer is ready. By the way, such holes can be pierced on the air hose itself, but it’s better not to spoil it and use a rubber spray nozzle.

There is another option. For example, a natural one looks very impressive in an aquarium, from which a lot of air bubbles come out. For this fit miotis porous or porous limestone. But in this case, two problems arise. First, it is necessary to take into account the influence of stone on the state of rigidity of the aquarium aquatic environment. And secondly, it is necessary to ensure reliable fastening of the edge of the outlet air hose to the stone. In principle, special silicone will help to successfully solve this problem.

If the “bank” is low and long (there are also such forms of aquariums), then air spraying should be done in several places. Otherwise, all the fish will gather in one aeration place.

You need to take a longer piece of rubber tubing (almost equal to the length aquarium), and pierce tiny holes in groups in several places at the same distance from each other. Such a tube can be laid at the bottom along rear wall and decorate a little. Columns of air bubbles will rise from these areas, evenly mixing water with oxygen. Yes, and such aeration looks very attractive.

With a normal content of ornamental fish and aquatic plants, a compressor is indispensable. Some advanced home crafters assemble such devices using standard electric motors, turn the flywheel and pump parts on lathes, place homemade devices in soundproof boxes. Of course, such technical homemade products are deservedly the pride of their owners.

However, in all other cases, it will be easier and more reliable to purchase an inexpensive commercial compressor, which, if properly maintained, will last a long time, providing pets with life-giving oxygen.
