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


AQUARIUM AERATION
or 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, the aquarium gets a “dead bog” in which disease-causing bacteria are swarming. 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 they need oxygen at night.

Well, now, before revealing the "aquarium-oxygen secrets," let's define

what is my oxygen concentration is normal

ANSWER: 5mg / l and more

Measure the concentration of O2 in the aquarium, you can with the help of tests that are sold in many aqua stores

Speaking about the concentration of oxygen, it is necessary to make a small reservation about overdose.

There are various opinions on this issue. Some, in the old-fashioned way, say that oversaturation of water with oxygen is dangerous. Other, more progressive comrades, on the contrary, say that the abundance of oxygen favorably affects the life of the aquarium. The arguments of both are interesting, but are a separate topic for conversation.

I personally tend to think that a lot of “oxygen does not exist” (conditionally, of course). Oxygen is poorly soluble in water, it is ten times worse absorbed than carbon dioxide. Therefore, in order to achieve an overabundance of O2 concentration, it is necessary to make a lot of effort, moreover, you need to be blind so as not to notice an overdose. Yes, the pH may drop sharply from an excess of oxygen, they say that colonies of beneficial bacteria are dying from its excess ... but this is such a rare situation that 99% of aquarists have never even thought about it.

And now, the promised tricks and secrets of aquarium aeration

Secret number 1: Many people know that oxygen consumption by hydrobionts increases with increasing temperature, since the respiratory process increases with increasing temperature. On the other hand, the concentration of oxygen in water is highly dependent on temperature. At a temperature of 20 ° С it reaches about 9.4 mg / l, at 25 ° С - 8.6 mg / l and at 30 ° С - 8.0 mg / l.

This statement can be perfectly used in cases of fish asphyxia. In addition, this statement disciplines beginners who think that plus or minus degrees does not matter.

Secret number 2: Perhaps the most valuable advice. Few people know about the benefits of using HYDROGEN PEROXIDE in an aquarium, this is what it does:

1. Revives choked and suffocated fish;

2. Fights against undesirable living creatures in the aquarium (hydra, planarians);

3. Fights against external protozoa and parasites;

4. Effective with bacterial infections on the body of the fish and its fins;

5. Fights against blue-green algae in an aquarium;

6. Fights algae on plants;

Very well talks about the benefits of hydrogen peroxide to many well-known and respected St. Petersburg aquarist V. Kovalev on the site "Living Water":

Hydrogen peroxide - This is an environmentally friendly product. In water, it breaks down into water and oxygen - harmless substances. Therefore, if it is used correctly, then the useful microflora in the filter and the soil can be saved completely, or only slightly podzadushit (too much oxygen is released in the overdose and in the filter, which is not good for bacteria). But the microflora will quickly recover, because no harmful substances have entered the water. Fish with proper dosing peroxide does not poison. If when applying peroxide on the sponge filters, the walls of the aquarium, fish and plants bubbles appear, then the dose was great. Only barely noticeable bubbles on mechanical filters are permissible.

Pharmaceutical 3% peroxide is used for:

1. VITALIZATION OF ASAFISHED FISH.

Addition to 40 ml on 100 l. When they begin to pour bubbles on the glasses, filters and, possibly, small fish, the water should be changed, the blow-down should be strengthened. If there is no effect after 15 minutes of exposure, then no longer fate ... For resuscitation of fish affected by high doses of carbon dioxide, 25 ml per 100 l is usually sufficient.

2. STRUGGLE AGAINST UNDESIRABLE AQUARIUM LIVING (planarian, hydra).

Concentration to 40 ml in 100 l. It is necessary to make a few days in a row before a complete victory over the enemy. At the same time, plants can be frozen, but if lower concentrations are applied, then it is not possible to win, although the plants will be alive. However, as a rule, everything turns out, the process takes a week or more. Anubias-type peristicular plants are relatively resistant to peroxide.

3. STRUGGLE AGAINST BLUE-GREEN ALGAE.

If your aquarium has your favorite plants, then you cannot exceed dosage 25 ml per 100 l once a day. Fish usually tolerate dose without harm 30 or even 40 ml per 100 l. The effect of daily application is noticeable on the third day. For a week, everything passes. The dose that you can still fight algae is 20 ml per 100 l. Long-stemmed plants with feathery leaves do not tolerate peroxide, so this dosage should not be exceeded. Stylist plants can be redeemed several times in a separately prepared peroxide solution 50-40 ml per 100 liters. Hold for half an hour, an hour. I do not know the exact time. They say that the fouling flip flops can be reduced. It is possible that peroxide will help in the fight against Vietnamese in the aquarium (20-25 ml per 100 l). But in this case it is still necessary to reduce the nitrate and phosphate contamination of water.

4. TREATMENT OF BACTERIAL INFECTIONS ON THE BODY AND ELIMINATORS OF FISH.

25 ml per 100 l daily or 2 times a day multiple times (7-14 days).
You can prepare a therapeutic solution of peroxide from the industrial product of perhydrol - about 30% of prekis. That is, it must be diluted 10 times to get an analogue of pharmacy peroxide. The substance is caustic and explosive! It is possible to dilute only with water in a plastic container. Contact with metal, alkalis, organic solvents should not.

Thus, taking into account the topic of the article, it should be said that hydrogen peroxide is "unique" and plays a crucial role! With its help you can instantly enrich the aquarium water with oxygen and thus save the fish, even in the severe stage of asphyxiation.

SECRET number 3: Many people know what oxygen pills are and many often use them when transporting fish. However, few people know and come across such aquarium equipment as OXIDATORS.

Oxidators are different: for the long transportation of fish, for mini aquariums, for large aquariums, for ponds. Their essence is simple - hydrogen peroxide is placed in the vessel to which the catalyst is added, after the reaction begins, as a result of which oxygen is released.

Video how oxidizers work for aquarium

Below is a line of oxidizers, which will reveal the whole point. OXIDATOR A

Dimensions: diameter 9 cm, height 18 cm

Container Content: for aquariums up to 400 l. - 250 ml of 3% hydrogen peroxide solution, for 600 l - 250 ml of 6% solution.

Duration of work: at a temperature of 25 ° C from two to eight weeks, depending on the concentration of the solution and the number of used catalysts.

The absence of bubbles coming from the device indicates the need for recharge of the OXIDATOR.

1 liter of peroxide is enough for 1 month for 20 large fish.

You can also use it in a larger aquarium, but the duration of the instrument is reduced.

If your aquarium has a capacity of up to 400 liters and the two-week OXIDATOR operation time is too small for you (for example, you are going on vacation), you can use two OXIDATORS A by placing one catalyst in their containers. As a result, the duration of their work before recharging will increase to four weeks.

MINI OXIDATOR

Dimensions: diameter 4 cm, height 6 cm

Container contents: - 20 ml of hydrogen peroxide solution.

Includes two 50 ml bottles with 4.9% hydrogen peroxide solution.

Duration of work: at a temperature of 25 ° C 2 - 4 weeks depending on the number of catalysts and the volume of the aquarium.

You can install up to four MINI OXIDATORS in an aquarium, or replace its catalysts with more powerful ones (from W, D or A OXIDATORS).

MINI OXIDATOR - DOESN'T REPLACE the compressor or filter, it is a universal oxidizer and works in the absence of electricity, long-term transportation of fish, increased demands on the oxygen content of the fish or summer increase in water temperature. Kills harmful bacteria and treats outdoor fish diseases.

OXIDATOR D

Dimensions: diameter 8.5 cm, height 8.5 cm

Container Content: for aquariums from 60 to 150l. - 125 ml of 3-6% hydrogen peroxide solution.

Duration of work: at a temperature of 25 ° C, 1 liter of peroxide is enough for 2 months of work in an aquarium with 10 large fish.

OXIDATOR W

The first safe and self-regulating device that can be year-round supply ponds with oxygen without the use of hoses and electrical wires, even in a fierce winter.

It is designed for garden ponds, as well as large aquariums in excess of 700 liters.

Dimensions: diameter 15 cm, height 18 cm

Container contents: 1 liter of 6-30% hydrogen peroxide solution.

Duration of work:

In the summer with a single refueling - 1-2 months.

In winter, under ice - for 4 months.

The annual need for a solution, depending on the temperature, is 3-5 liters.

FT OXIDATOR

Floats in the shipping container due to the ring float.

The device allows you to transport or contain a large number of fish (up to 25 goldfish with a body length of 8 cm in 20 liters of water) in a small container (can, thermo bag, bag, etc.) with a volume of 2-20 liters for a long time without an additional compressor or filling the bag with oxygen.

Duration of work - from 144 hours (at 9 ° C) to 36 hours (at 25 ° C).

OXIDATOR FTc

The FTC OXIDATOR compact device allows you to transport or contain fish in a small container (bucket, plastic bag, etc.) volume of 2-20 liters for a long time without an additional compressor.

Increased oxygen consumption by fish with increasing temperature (within reasonable limits) is automatically compensated by the device.

One OXIDATOR FTc contains 1000 mg of pure oxygen.

The working time at a temperature of 20 ° C is approximately 12 hours. As the temperature rises, the operation time decreases, but the amount of oxygen released increases. When the temperature decreases, the duration of work increases.

It is worth noting that oxidizers are very rarely used by aquaquimists in the post-Soviet space. They cost relatively not expensive - OXIDATOR A costs about $ 100, plus they save energy ... but alas, there is not even anyone to ask anyone about the practice. Most often they are used only for long shipments of fish.

AERATION - THE SOURCE OF LIFE OF OUR AQUARIUMS

Aeration, enrichment of aquarium with oxygen interesting video

Aeration of water in the aquarium

Aquarium fish, like all living things, need oxygen. But sometimes the natural concentration of oxygen is insufficient and the owners of aquariums must do aeration of the water in the aquarium.

Ways of aeration

Oxygen production for fish in an aquarium is carried out in two ways: natural and with the help of special compressors. The natural way of aeration is the divorce of plants and snails. Plants are capable of producing oxygen and can meet the needs of the fish in it. However, at night the plants themselves absorb oxygen and in aquariums at night there is often a lack of oxygen. Snails also affect the oxygen content in water, and they can even monitor the oxygen balance. Some species of snails crawl on the leaves of plants or on the walls of the aquarium when there is a shortage of oxygen, whereas under normal conditions they live on stones.

Artificial aeration is carried out in two ways:

  1. Air compressors. They deliver air through the spray through the air tubes. The sprayer turns the air into the smallest bubbles, which are more easily distributed throughout the aquarium. Compressors are specifically designed to supply oxygen to the water column.
  2. Water pumps, filters, pumps. They perform the functions of internal filters, driving the liquid through the sponge and those equipped with a diffuser suck air from the air tube. The air is mixed with water and the form of small bubbles is released into the aquarium.

To determine how much oxygen is needed in an aquarium, it is necessary to take into account its population, depth, volume of water, temperature, lighting mode, etc. If the aquarium is large and well planted with plants, self-sufficiency in oxygen is possible. However, modern compressors not only supply oxygen, but also contribute to the mixing of water and the strengthening of the soil.

Oxygen excess in aquarium

On the question of whether oxygen is needed in an aquarium, the answer is simple - we need it. However, some people perceive the advice of water aeration experts as a guide to action and start planting heavily. aquarium plants and use several compressors at once. They do not know that it is harmful for fish and may cause gas embolism. In this case, air bubbles appear in the blood of fish, which can lead to death. Therefore, the saturation of water in the aquarium with oxygen should be carried out according to the rules:

  • change water in small portions;
  • choose the right composition of fish;
  • keep track of the number of plants;
  • regulate the air flow from the compressor.

In this case, the perfect balance of oxygen will be achieved and your fish will not suffer.

COMPRESSOR FOR THE AQUARIUM AND EVERYTHING THAT IS NECESSARY TO KNOW ABOUT THIS.

Why do you need a compressor in an aquarium?

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. Данный процесс называется аэрацией, а подобные компрессоры иногда именуют аэраторами. Проще говоря, это воздушный насос

.Главные требования, которые нужно предъявлять к устройству при его выборе

Часто аквариум стоит в той же комнате, где люди отдыхают. 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.

Those. on the compressor housing A special regulator is provided which reduces the applied voltage, as a result of which a smooth adjustment of the supplied air by the compressor takes place.

It should also immediately be said that modern compressors are divided into several groups, for an aquarist they can be divided as follows, first of all it:

- compressor stations
- professional compressors
- Compressors for general consumption
- stand-alone compressors

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.

Types of compressors

The first type of pump delivers air through the movement of special membranes that allow air flow only in one direction. Such an aquarium compressor consumes very little electricity and operates with low noise.

The main disadvantage of this device is low power. Aerator is not suitable for large containers. However, for example, for a 150-liter home aquarium, a small membrane silent compressor will fit perfectly.

Another type of aquarium aerators - piston compressors. From their name it follows that air is pushed out with the help of a piston. These aerators are more expensive, but their advantage is high performance and durability.

True, the noise level of reciprocating compressors is somewhat higher than in devices of the first type. Such aerators are usually installed in large aquariums or columns.

Home aerators of both types are both powered by household electrical network, and from batteries. Each aerator kit includes a flexible hose from which pumped air comes out.

What is a battery-powered compressor used for?

There are situations when urgent transportation of fish is required. However, do not deprive the fish of such important oxygen for them. Otherwise, they may simply die. You can use the road device for a small aquarium. Such equipment operates on batteries, which are very easy to replace at the right time. The battery-powered compressor allows you to protect against the death of fish that are outside the stationary aquarium. Such equipment has small dimensions, so taking it with you on a trip is very convenient. A battery-powered device may also be necessary if the power is often cut off in the room. Such a device is recommended to keep in reserve absolutely all aquarists. This is due to the fact that even short-term oxygen deprivation is fraught with fish for death. The question of how to choose a compressor, even experienced aquarists are asked. Choosing a compressor you need to focus not on its price category, but on the amount of water that it can drive in one hour. It is desirable to acquire powerful silent compressors. You can use a homemade device.

Required compressor capacity depending on the size of the aquarium

Capacity of the installed compressor directly 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 compressors with high power. 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 Disadvantages

The main drawback of the compressor - this is noise. No matter how the manufacturers struggle for noiselessness, they have so far failed to win this fight. Yes, it was possible to reduce the performance of this parameter to 25-30 dB, but it is all the same, quite a lot. As a rule, aquariums are installed either in the bedroom or in the nursery, and since the compressor sometimes works around the clock, its noise in the night silence is very noticeable. Craftsmen are hiding compressors in self-made soundproof boxes, which is a good way out of this situation.
The second drawback is the work of electricity. And how do you know electricity and water are incompatible concepts. Therefore, when installing and operating a compressor, it is necessary to exercise elementary caution.

Compressor care, preventative maintenance

For perfect work behind the compressor, care is needed.. It consists in the following:
- regular replacement of air filters (if they are available at its entrance);
- control and replacement of rubber membranes (often because of the rupture of the membrane, the entire compressor is necessary, since it is very difficult to find a repair kit for a particular model);
- regular cleaning of the diffusers (pull out and rinse in clean water, thereby reducing the resistance of the diffuser);
- monitoring the condition of air hoses, and replacing them if necessary.

Alternative to the compressor in the aquarium

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 much time should the aquarium compressor work per day?

Konstantin Bogdanov

Depends on the population of the aquarium and its population of fish and plants. If the aquarium is normally populated with plants and fish are present in a small amount, then it is not at all necessary to aerate the water around the clock.
It can determine the compressor running time. Turn off the compressor and watch the behavior of the fish, if the fish begin to rise in the upper layers of the aquarium, and even more so grab air from the surface, immediately turn on the compressor. Judging by this data, make a conclusion about the compressor operation time.
If you have a filter with aeration function, it is better not to turn it off completely. It's easier for many reasons.
At night, it is highly desirable not to turn off the compressor. Although oxygen consumption by sleeping fish falls (however, there are night species), nevertheless, at night, plants emit carbon dioxide instead of oxygen. So without aeration in the aquarium, the densely planted fish have a great chance not to live until morning with the aeration turned off.
As a rule, beginners, ugly over-populate their aquariums and prefer to squeeze plastic Chinese garbage into aquariums instead of live plants, so I usually strongly recommend beginners to not turn off the compressor or filter at all.

Natalia A.

If you have a filter with aeration 2 in one 24 hours a day, turn off only for flushing as it gets dirty, if the compressor is separate, then you need to have the detailing — is there any living plants, is the density of fish landing.

How often should oxygen be included and for how long for goldfish?

Angela

Goldfish are demanding on the oxygen content. Many small tropical fish that are contained in aquariums, the need for oxygen is much lower. For example, many charicin fishes (neons, rhodostomoses, minors, etc.) can be successfully maintained in aquariums without special aeration. As a rule, the most demanding to the oxygen content of fish live in nature in rivers and streams with fast flowing, with rapids, rapids, waterfalls. Fish that live in slow-flowing rivers (especially with water that is rich in organic matter), small ponds and lakes, usually need less oxygen in the water.

An interesting question is about the role of aquarium plants in oxygenation of water. Some aquarists exaggerate this role. Indeed, in the process of growth of aquarium plants (in the light), they release oxygen, but its amount, as a rule, does not exceed what enters the water due to natural gas exchange with air.
At night, the plants absorb oxygen from the water. Therefore, despite the fact that the activity of fish decreases, and they require less oxygen, it may be a shortage. Fish may die from asphyxiation in the midst of plants. This phenomenon is observed at night in aquariums with a high density of planting aquatic plants (in the presence of plants floating on the surface). In such aquariums aeration is necessary, especially at night.
Aeration of water in aquariums is usually carried out using microcompressors through sprays of porous materials: sandstone, ceramics, porous metals.

Is it necessary to have an air tube in the aquarium? In general, why is it needed? Do all fish need it?

Vlad Nazarov

It is completely optional, Veronica.
If a:
- the aquarium is not filled with plants to the eyeballs on the principle of the Dutch,
- fish no more than 1 per 10 liters of water (and not larger than 5 cm each)
- feed with live food or good granulated, but moderately, and do not sprinkle it with spoons until the water spoils,
then air blowing is not a necessity.
Especially, if you keep labyrinths (macropods, gourami, cockerels, lyalius, etc.) - they don’t need to blow at all, even with a high density of landing.

Prince of Wales

Required.
The meaning of air supply is in mixing water, saturating with oxygen and removing carbon dioxide at night, when both plants and animals consume oxygen and release carbon dioxide.
During the day, when lighting the aquarium, it is not necessary to supply air if there are a lot of plants in the aquarium. Enough of that, which is obtained by photosynthesis. But at night, plants eat oxygen with fish and small fish (especially large ones) can easily suffocate.

Aquarium in the room.

Kitty @ Murys @

1, preferably constantly, if the aquarium with a lid, then oxygen will not be enough in any case ...
2-necessarily needed, and the more the better.
3 different types of fish, perhaps not compatible, and dominance ...
4-filters are of two types: internal and external, it all depends on the volume of your aquarium and the power of the filter ...
5-yes, there is nothing terrible in it, it is not recommended to put the aquarium on the light or near the window, from a large amount of light the aqua walls will begin to turn green ...

Gilyazov Timur

1. How long does oxygen supply to the aquarium work and when?
2. Do we need live plants, not just artificial ones?
3. Why do fish bite each other by the tails? (considering that they are different people)?
4. What are water filters and how to use them? (I have some drops but I don’t know enough of them)?
5. Is it possible to put an aquarium next to a computer monitor? (Yes, and just beside the computer)

Kat

1. oxygen is always, then you get used to the noise
2. Plants at will. Ideally, they produce oxygen, but in the presence of artificial is not necessary. Only garbage from them and dirt (from living)
3. That they are so played / hunted. It is necessary to check whether they can be kept together, and then more active and aggressive fish can clog the weak and sluggish.
4. Drops most likely to clean the water from bleach. Filters are better with charcoal. In the pet store ask.
5. In theory, maybe I was, everything was fine.
Good luck to you and your fish!

The aquarium is connected to the devices: water heater, oxygen and water purifier (combined with oxygen). The store said

Alex

The heater is surely with a thermostat, it turns on and off automatically. It is impossible to turn off the filter, bacteria settle in it, they will die without a duct, poison all aquas. After a long shutdown, you must carefully wash the filter element.

Alisa

A short shutdown for a few hours is no big deal.
The water heater is a thermostat, I have it turned off altogether, you buy a thermometer to always measure the temperature, I have always been above 24, even in winter, so I don’t use the thermostat, it just lies in the nightstand. By the way, it is better to buy an electronic thermometer (there are magnetic scrapers with a built-in electronic thermometer, very convenient), and ordinary people often lie (I have 2 degrees).
Oxygen and water purifier - this pump should work all the time.
Well, turn on the light for 8-10 hours, I have 10 hours on, turn off for the night.
But on the dacha, I specifically bought a spare compressor (the pump can fail) and oxygen pills, just in case of light cuts. Well, there is a generator ...

Irina Bespalova

Neons are fishes that find it difficult to live without constant oxygen in an aquarium. But turning off the light is not a bad thing even for a day. Water heater - no big deal. If the temperature of at least 23 degrees can be turned off for a week.
Oxygen - you can turn it off for 2 days, it's okay (if you can have gouras without it)
Filter - it is advisable to work around the clock, but the stoppage for 1 day is not terrible (I advise you to listen to Alex’s opinion)

Aquarists ... But should the filter always work in an aquarium, or should all of them be turned off for a while? ATP =)

Rita Dyomina

"In modern aquarism, filters are one of the most important means of livelihood. Aquarium is a closed biological space in which there is a constant accumulation of organic residues: fish produce excretions that pollute water; plus uneaten food, dead plant parts, etc. In natural waters, concentration waste in the water is fairly stable, because some of them are processed into minerals and assimilated by plants, and the other part is carried out with water streams. Its density of planting is significantly higher than natural, therefore metabolic products and their inorganic derivatives can have a negative impact on its inhabitants. The main methods of removing excess mineral and organic residues from an aquarium and establishing acceptable living conditions for fish in it are filtering, cleaning, and water changes. " The filter should work around the clock. When the filter is turned off for more than two hours, everything that has been filtered in the filter element will decompose and if it is turned ON WITHOUT WASHING, then everything will be thrown into the water on all inhabitants. The frequency of leaching depends on the density of fish landing, on the ability to feed the fish, etc.

The filter is turned off for bathing as already noted, as well as some are turned off when feeding fish for 20 minutes at maximum. If it makes noise and interferes with sleep, then find a more noiseless one or solve the problem with the option of supplying air due to which noise is the case with filters.

Фильтр более сложная система, чем можно подумать, даже если рассматривать недорогие внутренние фильтры. Помимо механической фильтрации, любой фильтр, худо-бедно, но обеспечивает биологическую фильтрацию. Последняя осуществляется колониями бактерий, которые селятся субстрате (в нашем случае - губке) фильтра. The vital activity of a given colony of bacteria directly depends on the direct current of water, which brings nutrients to the microorganisms. If the filter is stopped, this colony starts to lack organic matter and oxygen and gradually dies. Moreover, this process occurs very quickly, over forty minutes. After the bacteria die, others, adapted to life in stagnant water, take their place. And then the most unpleasant thing happens - the inclusion of the filter. After its inclusion, all this fraternity falls into the water column. Predict what can happen after that, hardly anyone would agree

In the aquarium, the pump with the filter should work forever ??? Now the aquarium is under preparation !!! There are no fish yet!

the equipment in the aquarium should work all the time ... all the more so that you are new to this business and you still do not fully understand the processes in aquas ...
if the aquarium is of a small size (up to 100 liters), it is possible to use an internal filter with aeration ... if it is more than 100 liters, buy an external filter, but you also need an air compressor for it
if you have any questions - visit the aquarium community "Aquarium at home" //my.mail.ru/community/akva-xobbi here will always help and prompt

Always and filter and compressor. You will turn off the air at night, the fish may suffocate (well, it depends on how many inhabitants live in aquas).
And the filter should work even if there are no fish in aquas. And then the water can stagnate and go nafig.

Even when preparing the aquarium, if there are no fish yet, filtration and aeration of the aquarium should be carried out continuously. The working filter settles useful bacteria, which creates an environment in the aquarium, and establishes a biological balance; only because at night the fish, the plants will consume large amounts of oxygen, and the plants also release carbon dioxide into the aquarium, which without aeration will be dangerous for the fish. Get a 2 in 1 pump, aeration and filtration at the same time.

Everything can be turned off if it interferes, except for the filter. Unwanted bacteria can develop in the anaerobic environment, poison all the fish every other day. And aerobic oxidants will die. Light ideally 12:12. Aeration without strong overpopulation is not needed at all if the filter is working!

Olga Taranina

A filter pump will be needed when you run the fish in an aquarium - then it should work around the clock! Especially, it will be needed at night when oxygen will be consumed not only by fish, but also by plants.
