Air supply to the aquarium

maintenance, care, compatibility

Oxygen is vital for all creatures, including aquarium fish. It would seem that it should produce green plants. But, unlike the natural conditions, domestic water bodies have a limited volume and there are no currents in them that would update the water.

And the plants themselves are consumers of this gas (in the dark), along with the other inhabitants. Therefore, the oxygen concentration in the aquarium drops and additional aeration is necessary.

In this article we will talk about what aeration is, why it is needed, how to organize it, what happens when there is a shortage or an excess of oxygen. So let’s go!

  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.

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

Aeration, enrichment of aquarium with oxygen interesting video

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.

It has already been mentioned that a larger number of small air bubbles have the best effect on the degree of oxygen saturation of water. This is achieved with the help of the so-called sprayer, which can also be made independently.

Special knowledge and skills are not needed here.

First way: use of a short rubber tube that is put on the outlet hose. It is enough to pierce a set of holes with a needle from all sides of the tube, firmly plug its free end – and the sprayer is ready.

By the way, such holes can be punctured on the air hose itself, but it is better not to spoil it and use a rubber spray nozzle.

There is another option. For example, a natural stone looks very impressive in an aquarium, from which a lot of air bubbles come out. For this fit myotis porous or porous limestone.

But in this case, there are two problems. First, it is necessary to take into account the influence of the stone on the state of the rigidity of the aquarium aquatic environment. And secondly, it is necessary to ensure reliable fastening of the edge of the output air hose to the stone.

In principle, a special silicone will help to successfully solve this problem.

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

You need to take a longer piece of rubber tube (almost equal to the length of the aquarium), and pierce the tiny holes in groups in several places at the same distance from each other. This tube can be placed on the bottom along the back wall and slightly decorated.

Columns of air bubbles will rise from these areas, uniformly mixing water with oxygen. Yes, and looks like aeration is very attractive.

With the normal maintenance of ornamental fish and water plants, a compressor cannot be dispensed with. Some advanced home craftsmen assemble such devices using standard electric motors, grind out the flywheel and pump parts on lathes, and place homemade devices in soundproof boxes.

Of course, such technical home-made deservedly are 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 used, will last a long time, providing pets with life-giving oxygen.

How to make an air sprayer for an aquarium :: Do-it-yourself aerator for aquarium :: Different

In pet stores there is a fairly wide range of aquarium accessories, including nozzles for an aerator that spray air in the form of small bubbles. Nevertheless, many aquarists prefer to do these dispensers with their own hands.

The question “How to view where the order goes” – 2 answers

  • – compressor;
  • – long flexible tube;
  • – needle;
  • – porous stone or piece of porous wood.

1. Aquarium inhabitants need a sufficient oxygen content in the water for a full life. Now there is a large variety of aerators designed to cope with this task. They operate according to the same scheme: outside air is pumped through a hose into the aquarium and sprayed, and the smaller the bubbles, the better the aeration.

Pet stores offer nozzles for air compressors at reasonable prices, but some aquarists are not satisfied with their monotony, while others just enjoy creating the equipment for a home pond on their own. Anyway, in the presence of suitable materials it is rather easy to make a sprayer.

2. The simplest option is a long rubber tube (perhaps the aerator hose itself), on which frequent, as in a sieve, holes are made with a simple needle. One end of the tube is attached to the compressor, and the other is blocked to allow air to escape through the punctures.

This design can be placed under the ground along the back wall of the aquarium, and the rising bubbles will not only provide its inhabitants with oxygen, but also create additional decor.

3. Nozzles for a compressor can also be made of any porous materials that do not emit harmful substances into water, for example, from abrasive stone and porous wood species. Before placing these sprayers in the aquarium, they must be sterilized in boiling water.

In order for the air to be well distributed, the nozzle must ideally, without gaps, be fitted to the tube through which the air flows.

4. It is not recommended to use synthetic materials (household sponges, etc.), since it is likely that they will release substances into the water that may adversely affect the health of aquarium inhabitants and even lead to their death. Chasing a beautiful design or low cost, we should not forget that the aquatic biosystem is quite fragile and sensitive to any changes.

If you are not sure about the safety of the material used for the sprayer, it is better to give preference to the purchase option.

5. It is important to note that small bubbles require more air pressure, which means that the load on the aerator increases. This can affect the rate of natural wear and tear, energy consumption and noise background, which is almost inevitably created when the compressor is running.

Sprayers, both home-made, and purchased, tend to clog, therefore, subject to periodic replacement.

The use of synthetic substances is not recommended.

Before you start creating a sprayer, well study the characteristics of the material: does it emit toxic substances, does it change the acidity of water, etc.
