Air for fish in an aquarium

maintenance, care, compatibility

Being a device for creating pressure (compression), the unit delivers air directly into the aquarium environment. This process is very important for ornamental flora and especially fauna.

Fish are known to breathe through the gills with oxygen dissolved in water. If there is little oxygen in aqua, the very existence of pets will be at risk.

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

In the domestic artificial reservoir, such air saturation is performed using aeration — forced, controlled supply of air flow into the aquarium water. Moreover, the smaller the air bubbles emerging from the compressor, the more dissolved air is formed in the water space.

You can say this: a compressor is an ordinary air pump.

The main types of professional aquarium compressors

Such a device can be assembled, if you understand the basic principle: first you need to somehow accumulate air, and then gradually submit it to the aquarium. This is the fundamental difference between an improvised unit and commercial piston or diaphragm pumps operating from an electric motor.

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

So, in order to quickly and without special difficulties to assemble an aquarium compressor, you need:

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

Three tubes should be taken from the tee: the first to the hand pump, the second to the inflatable ball, and the third tube (a dropper hose with a clip) will be the output hose. The end of this hose must be firmly plugged, and in front of it a tube must be punctured with several small holes, from which air will flow.

Of course, all connections must be reliable and tight.

To collect air using a tee, the pump-chamber line opens first. The ball chamber is very durable 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 enter the aquarium gradually, the diameter of the outlet tube in one place is regulated by means of a clamp. Naturally, this clip should be outside the aquarium, closer to the tee.

Experienced way selects the flow rate of the air flow.

In principle, a homemade compressor is ready. The disadvantage of such a device is that the battery chamber must be periodically pumped. As a rule, for normal aeration of an aquarium with a capacity of up to 100 liters, such pumping should be carried out 2 times a day.

Consequently, a homemade compressor can not be left unattended for a long time.

  1. Increasing the temperature of the water in an aquarium increases the oxygen consumption of its inhabitants and vice versa. Knowing this, you can quickly help the fish in case of asphyxiation.
  2. Hydrogen peroxide. Few people know about its use in an aquarium. She can:
  • revive choked fish;
  • fight against undesirable living creatures (hydras, planarians);
  • assist in the treatment of fish (bacterial infections, parasites, protozoa);
  • fight algae on plants and aquarium.

But you need to know how to use it correctly, otherwise you can only bring harm and poison all the fish. In this article we will not dwell on this.

If someone is interested in this question, then the information can be found on the Internet.

  1. Oxidizers They are of different purposes: for long transportation of fish, for small and large aquariums, for ponds. The essence of the work: hydrogen peroxide and a catalyst are placed in a vessel. As a result of their reaction with each other, oxygen is released.

In conclusion, I will say that you should not underestimate the importance of aeration in an aquarium. Moreover, there is a large selection of equipment for it.

You can find cheap and quality models.

When choosing a device, it is necessary to compare its capacity, the displacement of the aquarium, the number of inhabitants and their CO requirements.2. Typically, manufacturers indicate the recommended volume for each model.

And remember that only an aquarium with healthy conditions for the inhabitants can be beautiful.

Oxygen is supplied to the water column. The air passes through the tubes and enters the sprayer, where it turns into the smallest bubbles, which are distributed throughout the aquarium.

Compressors can vary in capacity, performance and maximum depth of pumping water. There are even submersible models with backlight.

The whole system consists of:

1. Air duct systems. It is better to take them from synthetic rubber, vinyl chloride or bright red rubber. Avoid rubber medical hoses, black or yellow-red tubes (they have toxic impurities).

Pay attention to the elasticity, softness, length.

2. Adapters. Made of plastic and metal. The latter is more durable and aesthetic, although more expensive.

On adapters can be cranes regulators. They allow you to measure the flow of air to each sprayer, if there are several.

3. Check valves. Tetra products are considered the best.

They are reliable and convenient to install.

4. Spray guns. They can be bought or made independently.

They are made of wood, stone, expanded clay, etc. In any case, the spray must be of high quality, dense and produce small bubbles.

Available sprayers in the form of short cylinders. They are placed on a stone or a short distance from the ground and decorated with stones, snags, stone ridges or plants. There are also long tubular products with a length of 20-60 cm.

They are placed along the back or side wall at the bottom.

It is better to place the compressor near the heater in order not to create different temperature zones in the aquarium.

In this case, the moving bubbles will stir the water, leaving no unheated layers at the bottom, and pull the liquid from the bottom up, where there is more oxygen. Another important point: the compressor must be above the water level or have a non-return valve.

The main disadvantages of compressors are noise and vibration. You can fix them like this:

  1. Place the instrument in a casing that absorbs noise (eg foam).
  2. Take it to the pantry, another room, to the loggia or mezzanine. At the same time, the long hose is hidden under the plinth. This option is only possible with a powerful compressor.
  3. Place foam rubber dampers under the device.
  4. Connect the device through a step-down transformer. It is worth considering that the performance of the compressor will decrease.

The device must be maintained: regularly disassemble and clean the valve.

Disinfection of water using a UV sterilizer.

First of all, a surplus of2 no less harmful than a disadvantage. It can cause gas embolism in fish when air bubbles appear in their blood.

As a result, the fish may die. Fortunately, such a phenomenon is rare.

Nevertheless, you should not be zealous with aeration (for example, it is not necessary to install several compressors).

Please note that the rate of oxygen concentration is 5 mg / l and a little more. Measurements can be performed using special tests purchased at a pet store.

Changing water in small portions, controlling the composition of fish and the number of plants, regulating the flow of air from the compressor will help to achieve the perfect balance.

Aquarium Aquarium: Methods and Methods of Enriching Aquarium Water with Oxygen

Everyone knows that equipment for aeration of aquarium water is paramount and vital.

However, many beginners and even already experienced aquarists do not know how it works, they do not fully understand why it is needed and what happens in an aquarium with a lack or excess of oxygen.

In this article, I would like to try in a simple narrative manner to lift the veil of aquarium aeration secrets, to bring excerpts from the already written material of Runet, and also to tell about some of the “secrets” of O2 supply to the aquarium.

I think I should start with a short story about mechanical aeration, by which I mean the process of mixing air with aquarium water using aquarium equipment (pumps and compressors).

The principles of operation of such equipment are well known and understood by everyone, so I will not focus on them. It is more interesting to tell about two misconceptions of newcomers of the aquarium craft, connected with the aeration of the aquarium water by mechanical means:

1. Usually everyone thinks that the enrichment of water with air occurs through bubbles, which the compressor will drive into the water. However, it is not!

Mixing air with water occurs on the surface of the water. The aerator creates vortices and vibrations from bubbles on the water surface, as a result of which mixing occurs.

We can say that the saturation of aquarium water with air (oxygen) is not due to the bulbushes, as such, but from their intensity and water flow, which improves the absorption of oxygen from atmospheric air.

2. The second important nuance of mechanical aeration is its continuous operation. A big mistake for beginners is to turn off aeration for the night, so that it does not rustle.

Such an action can lead to fatal consequences, because overnight asphyxiation will “earn” not only fish, but also all hydrobionts, up to nitrifying bacteria, which leads to a disturbance of biobalance and, as a result, a “dead bog” is obtained from the aquarium, which is infested with disease-causing bacteria and live algae!

With that said, it should be noted that you should not save money when choosing and buying equipment for aeration of the aquarium, it must be of good quality and sufficient power. It is desirable that it had various nozzles and created a good “purge”.

A huge role in the “aeration of the aquarium” is played by live aquarium plants. Aquarium plants are perhaps the only natural source of “pure” oxygen – O2, which is released during photosynthesis.

The presence of abundant vegetation in an aquarium will have a favorable effect on its climate and, in particular, on the concentration of oxygen in the water. However, the plants are not a stable and unconditional supplier of oxygen to the aquarium.

It is worth saying that the process of photosynthesis, in which plants emit oxygen is possible only if there is sufficient illumination and the necessary amount of CO2 (carbon dioxide). As soon as the light in the aquarium turns off, the process of photosynthesis stops and the opposite happens – the plants begin to consume oxygen.

From the above, we can draw two conclusions:

– aquarium plants are not replaceable helpers “oxygen supply in the aquarium.” I generally keep quiet about their use in setting up the biobalance and their participation in the fight against NO2NO3.

– Alas, aquarium plants are not a panacea. Many people are mistaken in thinking that plants need only carbon dioxide, no!

They also “breathe” and oxygen is vital for them at night.

Well, now, before disclosing “aquarium-oxygen secrets,” let’s determine

What aquarium fish live without oxygen and air

And so, the fish breathe oxygen, which is contained in the water. This happens with the help of a special organ of respiration – the gills, which in turn come in various shapes.

As a rule, the gill slits are located on the sides (about 4-5 pairs of gill lobes). The water washing and passing through the gills gives up the oxygen dissolved in it and carries away the carbon dioxide that has been emitted.

Further, the “extracted” oxygen is spread throughout the body of the fish.

However, some species of aquarium fish can breathe skin or take in air into the cavity of a floating bladder. In addition, there is the so-called intestinal breathing, which is possessed by aquarium catfish (speckled catfish corridoratus) and loachworms, which can get air into the intestine with the help of the anus.

I think that all those who have speckled catfish have seen how they rise from the bottom of the torpedo to the surface of the water and back – this is exactly the same thing – intestinal breathing!

And now we are getting to the question that interests us! Some species of fish have special organs with which oxygen is absorbed.

One of these organs is the gill labyrinth, whose owners are classified as LABYRINTH FAMILIES. A labyrinth is a specialized respiratory organ that allows you to absorb oxygen directly from the air.

Labyrinth fish take the air “swallowing” it from the surface of the water. Therefore, such aquarium fish aeration is not needed!

However, if access to the surface of the water is closed, such a fish will soon die.

What kind of labyrinth fish can live without oxygen, here they are:

In Asia, a lot of rice fields and it is there that live fish adapted to breathing atmospheric air. These are, in particular, labyrinths that have a labyrinth labyrinth organ (labyrinth).

It consists of winding canals, the walls of which are formed by bone plates covered with films with blood vessels. Contract labyrinth enters the perch-shaped detachment.
The labyrinth organ makes it possible to survive in water, where there is practically no oxygen. Moreover, if labyrinth fish interfere with breathing air, it will die even in oxygen-saturated water. Therefore, keeping such fish in an aquarium, it is necessary to ensure that floating plants do not completely cover the surface of the water.

And there is also the African labyrinth fish – Ktenopoma.
