How often do I need to turn on the air pump in the aquarium? And very quickly the water began to smell. Partially changed did not help

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.

How Should The Filter Work In The Aquarium

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

1. Usually everyone thinks that the enrichment of water with air occurs through the bubbles, which the air pump 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.

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.

– 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

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

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.

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.

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;

Hydrogen peroxide 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.

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 favorite plants, then you should not exceed the dosage of 25 ml per 100 l once a day. Fish usually tolerate a dose of 30 or even 40 ml per 100 l without harm. The effect of daily application is noticeable on the third day. For a week, everything passes. The dose that can still be controlled with algae is 20 ml per 100 l.

Long-stemmed plants with feathery leaves do not tolerate peroxide, so this dosage should not be exceeded. The hard-leaved plants can be redeemed several times in a separately prepared peroxide solution of 50-40 ml per 100 l. Hold for half an hour, an hour. I do not know the exact time. They say that the fouling flip flops can be reduced.

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

25 ml per 100 l daily or 2 times a day many times (7-14 days). It is possible to prepare a therapeutic peroxide solution from the industrial product of perhydrol – approximately 30% can be obtained. 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.

How often should I turn on the filter in the aquarium?

The filter in the aquarium is the most important part of the equipment, the life support system for your fish, which removes toxic waste, chemistry, and if it works correctly, it saturates the water in the aquarium with oxygen.

For the filter to work properly, it is necessary that useful bacteria are divorced inside it, and improper care kills them, creating problems with balance as a result. Unfortunately, most filters lack simple and understandable instructions for the user to understand.

All filters are different, small ones need to be washed weekly, and large ones can work without problems even for two months. The only correct way is to observe how quickly your filter becomes clogged with dirt.

In general, for the internal filter, the frequency is about once every two weeks, and for the external one from two weeks for very polluted aquariums, up to two months for cleaner ones. Look for the flow of water from the filter if it is weakened – this is a signal that it is time to wash it.

– These are the simplest and at the same time effective filters for an aquarium. Some "old-fashioned" call them "glasses." The essence of their work is very simple – the filter has a pump (motor) and an absorbent sponge. The pump pumps the aquarium water, which passes through the sponge, is cleaned. Such filtration effectively copes with the removal of large contaminants: food residues, fish excreta, residues of dead organisms, etc.

If you have a small aquarium and not very large fish swim in it, such a mechanical filter will be quite enough.

– These are filters that provide filtering through various absorbents. The most common absorbent is aquarium coal. Also in the aquarium used and other absorbents – ion exchange resins, for example, zeolite. Filters that provide for the possibility of such filtering are more practical than mechanical ones.
