Is It Possible To Add Hydrogen Peroxide To The Aquarium

Can I add hydrogen peroxide to my aquarium?

Before I start talking about hydrogen peroxide (H2O2), I want to draw your attention to the fact that I used this method in order to clean the aquarium after a flash algae, which was my main and most important problem.
This article is not talking about long-term use of H2O2 to fight algae, but it can effectively clean your aquarium and aquarium equipment after you have solved this problem.

H2O2 can be used in the same way that many people use whiteness to clean their equipment when they get it out of the tank. The main advantage of hydrogen peroxide is that you do not need to rewash all equipment after using it before placing it in the aquarium. In addition, this is what will be discussed in this article, H2O2 in the aquarium kills almost all types of algae.
I did an experiment to test this in a 200 liter aquarium in which black beard was the main problem. First, I went to the pharmacy and bought H2O2.

The aquarium had quite bright lighting and no CO2 was added to the water, as a result of which a “beard” began to grow on snags and decorations, as well as slow-growing plants such as anubias. After the CO2 supply system was installed, the growth of algae stopped, but the beard did not want to leave its homes. After several attempts to withdraw it completely, I decided to use H2O2.

The first thing to do was trim all affected plants. I didn’t want to actively “heal” the plants, in addition, cutting off old leaves will push the plants to grow new ones quickly. Then, using a large syringe, he injected H2O2 around the areas where the algae grew and turned off the filter to reduce the movement of water. Then, using the same syringe, I sprayed about 50 ml of the substance directly onto the algae (1 ml per 4 liters of water). I did not plan to use more H2O2. All plants began to emit air like crazy, thanks to the high level of oxygen in the water. After 15-20 minutes, I did a routine water change, which I do regularly, replacing about 25% of the old water with new one, and then turning on the filter again. The beard, like all plants, bubbled like crazy for the rest of the night, turned pinkish-red in 24 hours, and after a few days was completely eaten by the fish in the aquarium. The next week, I repeated the same procedure on other areas covered with algae, and so on with a frequency of several days. I worked on the remaining areas with algae for a week until the beard left the aquarium completely. The whole procedure took about 3 weeks. Then I soaked in a separate container all the equipment from the aquarium in water with a high concentration of H2O2, about 10 ml per 4 liters of water.

There were no problems with fish and plants in the treated aquarium. True, I do not have floating plants at all in my aquarium, so I cannot say for sure what their reaction will be when hydrogen peroxide is added to the water. Now I add a couple of drops of H2O2 to the heater and to the spray in the filter so that they are not covered with algae, but this is more likely for prevention, because I have not had more problems with algae in this aquarium.

In another aquarium, I used the same method to get rid of the so-called cladophora on the groundcover and it worked out as if by magic.!

Aquarium: 45 liters.
Problem: thread.

I ran one of the fry aquariums a little, without changing the water in it for a month, without adding fertilizer and not giving enough light, as a result of which it acquired a rather unhealthy look and filament appeared on the ground cover plants. My first thought was to lower it and restart it again, but I really wanted to check the effect of adding H2O2 there and I decided to try it. To begin with, with the help of a toothbrush, I tried to remove the thread that gave in, and left the one that did not want to come off the plants. This is what the aquarium looked like before H2O2 was added.

The next day the algae looked much softer in texture, but I was still not sure if the treatment was successful. After another couple of days, the thread disappeared, as if it had never existed!

You can pay attention to the stem of the plant in the photo above, after the procedures, it began to actively grow and after about a week it began to release young shoots.

Conclusion:
H2O2 is an excellent helper in the fight against algae. You will not be able to use it all the time, as I am not sure that long-term addition of this substance will not affect the plants, but as a way to quickly clean the aquarium, this method is much safer than many others, such as using algicides. Plus, hydrogen peroxide is not expensive, but on top of that, H2O2 can be useful to you in addition to being used in aquarium hobby, in ordinary everyday life. For example, if you want to clean out your artificial plants.

Caution:
Once, when adding H2O2 to the water in a cichlid, I lost one fish, apparently due to concentration. I believe that hydrogen peroxide is more hazardous in high pH water. Please always start adding small amounts of H2O2 before increasing it. Personally, I find it better to add this substance in small doses several times than a large dose in one large portion. This is optional when soaking equipment.

And do not forget to use climatic complexes such as air o swiss 2055, which are also usually recommended by doctors for families with small children.

Treatment of fish with hydrogen peroxide

With the help of three percent hydrogen peroxide in a dosage of 25 ml per 100 liters daily or 2 times a day for (7-14 days), fish can be cured of mild forms of columnariasis, false neon disease, gill and fin rot, as well as saprolegniosis. And the most important thing. From amoebiasis, which has recently become a disaster for aquarium fish.

Hydrogen peroxide in the aquarium:
how to use it correctly?

How can you replace hydrogen peroxide from a pharmacy?

Using hydrogen peroxide to help choking fish or “revitalization” suffocated.

Fish can begin to choke for several reasons: during long-term transportation, in case of an overdose of carbon dioxide in the aquarium, when the aquarium overheats, just when the power goes out and the aquarium equipment stops.
If the fish feels very bad after long transportation, lies on its side, the movements of the gill covers are convulsive irregular or barely noticeable, then adding up to 40 ml per 100 liters (up to 8 drops per liter) of peroxide can bring it back to life. If bubbles begin to pour out on glasses, filters and, possibly, fish, the water will need to be partially replaced, the blowing will be increased. If after 15 minutes of exposure there is no effect, then it is no longer destiny.
To resuscitate fish affected by high doses of carbon dioxide, it is usually sufficient to add 25 ml of hydrogen peroxide per 100 liters to the aquarium and increase the aeration of the aquarium.
When there is a power outage to prevent the fish in the aquarium from suffocating, it is best to use a battery-powered oxidizer or compressor. And if this equipment is not available, then you will have to use hydrogen peroxide. In this case, add 20. 25 ml / 100 l. The fish should be watched and peroxide added again when the fish begin to experience oxygen starvation: swim near the surface and breathe heavily.

Disinfection of aquarium and aquarium equipment with hydrogen peroxide

In high concentrations, hydrogen peroxide destroys the causative agents of diseases in aquarium fish. Adding three percent peroxide to the aquarium at a dosage of 200 ml per 50 liters per day will ensure good disinfection. Beforehand, it is necessary to remove soil and plants from the aquarium. The soil should be well rinsed and then either calcined or treated (filled) with peroxide. How to deal with plants is described in another material. After using hydrogen peroxide, simply drain the water and refill it. Thorough rinsing of the aquarium is not necessary.

There are several reasons for adding hydrogen peroxide to your aquarium. In a quarantine aquarium, in a container for receiving new fish and at the same time getting a positive result. But we must not forget that hydrogen peroxide is an aggressive substance, therefore, mistakes when working with it will give a negative result.

Using hydrogen peroxide to combat intruders in the aquarium: planaria and hydras.

Hydrogen peroxide has a depressing effect on planarian and hydr. However, it is safer and more correct to use No-Planaria or fenbendazole-based drugs (see Forum Topic). But they may not be at hand. Then we use hydrogen peroxide. Concentration up to 40 ml in 100 liters. It is necessary to enter several days in a row until the complete victory over the enemy. Plants can be killed at the same time (hornwort and “long-stem” will definitely suffer), but if you apply lower concentrations, then you may not win, although the plants will be alive. However, as a rule, everything works out, the process takes a week or more. Stiff-leaved plants such as anubias are relatively resistant to peroxide. It is unacceptable to use hydrogen peroxide in a shrimp aquarium. Unfortunately, planaria are usually found in shrimp.

Read immediately about what to do in case of an overdose (if too much hydrogen peroxide is poured into the aquarium)?

In our difficult times, when choosing one or another drug for adjusting the hydrochemical parameters in an aquarium or a medicine for fish, not only its availability, but also the price plays an important role. Pharmacy hydrogen peroxide is both cheap and readily available.

If you use hydrogen peroxide correctly, then the beneficial microflora in the filter and soil can be kept intact, or only slightly suffocated (in case of an overdose, even atomic oxygen may appear in the filter or too much molecular oxygen released, which is not useful for bacteria). But the microflora will quickly recover, because when using peroxide, harmful substances do not enter the water.
With the correct dosage, peroxide does not poison fish. If, when applying peroxide, bubbles appear on the filter sponges, the walls of the aquarium, fish and plants, then the amount introduced into the aquarium was too large and it can be harmful to the fish. Only a barely noticeable appearance of bubbles on the lips is permissible. Be extremely careful when using hydrogen peroxide in aquariums with hard water from an artesian well.
Currently, there are preparations on sale (JBL Ektol cristal, sera ectopur). In certain cases, replacing hydrogen peroxide and much less dangerous in inexperienced hands, however, incomparably cheaper peroxide is available in any pharmacy and this is its main advantage.

The benefits and dangers of hydrogen peroxide in an aquarium

Hydrogen peroxide. An environmentally friendly product and this is very important. Peroxide. Not a bad medicine for fish. There is no need to change the water after applying the peroxide! Oxygen and water. This is all that remains after her!

Disinfection of the aquarium

Hydrogen peroxide in high dosages is an excellent antiseptic. It is capable of destroying the entire microflora, while it does not require subsequent washing of the inner surface. this is its fundamental difference from most other drugs. If you have whitish worms in an artificial reservoir, for example, planarians, and small snails have proliferated too much, you urgently need to connect “heavy artillery” in the form of peroxide.

Before processing, it is necessary to remove everything that you want to protect from the tank. fish, aquatic plants and all kinds of invertebrates. 30–45% perhydrol is poured into the container (note that this is not a pharmaceutical 3% solution, but a strong industrial composition). it must be diluted with water so that a concentration of 4.5–6.5% is formed.

Important! You should work with this solution with gloves, otherwise there is a high risk of severe burns. After the container has been processed, all the liquid must be drained, and then carefully siphon the soil in order to destroy the dead organic matter.

Operating principle

When hydrogen peroxide enters the water, it begins to decompose into oxygen and hydrogen, thereby enriching the stagnant liquid in the aquarium. At the moment of interaction of peroxide with cells and tissues of lower microorganisms, an oxidation reaction occurs, which largely contributes to the destruction of unwanted pathogenic flora. The onset of action of the drug can be judged by air bubbles that rise from the bottom of the tank.

Fish treatment

One of the main problems that fish face is oxygen starvation. It can happen in several cases:

  • With low power or complete absence of compressors;
  • When the water temperature rises;
  • Overpopulation of fish.

In such situations, pets do not have enough oxygen, they begin to suffocate. then hydrogen peroxide becomes a real salvation for all representatives of the aquarium fauna. As a rule, the visible effect of the use of the agent is noticeable already 15-25 minutes after the addition of the medicinal solution: the fish quickly come to their senses and from the surface of the water begin to swim away to their hiding places. With the oversaturation of an artificial reservoir, fish are often poisoned with ammonia contained in the waste of pets.

Depending on the state of the fish, a peroxide solution is used in a volume of 1 to 3 ml for every 10 liters of water. From the very first minutes, hydrogen peroxide begins to work, making it easier for pets to breathe and significantly accelerating oxidative processes, as well as stimulating the breakdown of nitrates and their excretion from the body. It can be said without exaggeration that drugs that act as quickly as hydrogen peroxide simply do not exist.

The drug can also be used to treat the following diseases experienced by fish:

  • Fin and body bacterial infections;
  • Attack of the gills by parasitic microorganisms;
  • Skin lesions by parasites.

If the problem is insignificant, the disease is at an initial stage, then fish can be treated in a common reservoir. In this case, the proportion of the injected drug is 2.5 mg per 10 liters of water, the procedure is carried out twice a day for a week. If the fish has severe skin lesions, then you can cure it with peroxide baths, usually such procedures are very easily tolerated by the fish. To do this, water is poured into a separate tank and the fungicide is diluted from the ratio of 1 ml of peroxide to 1 liter of water, and the diseased individual is placed there for 10-15 minutes.

With severe fin rot, baths also help, they are carried out in the same way, only the concentration of the drug is used a little higher. 4 ml per 1 liter of water. Processing takes about 30-50 minutes. Fin rot therapy is done twice a day until the fins begin to heal. After that, the therapy is continued in the same way as if the infection was weak, that is, in the general aquarium.

Hydrogen peroxide for aquarium: dosage and application

  • Operating principle
  • General terms of use
  • Fish treatment
  • Algae control
  • Disinfection of the aquarium
  • Emergency situations

Hydrogen peroxide is an affordable and very effective drug used to solve a wide variety of aquarium problems. It helps oxygenate the water, get rid of unwanted vegetation, and heal some bacterial and fungal infections in fish. However, you should be extremely careful with peroxide. any increase in the permissible dosage will inevitably lead to the death of aquatic inhabitants.

Algae control

Hydrogen peroxide is often used to get rid of overgrown algae. Blue-green algae often appear in aquariums with low oxygen levels. They multiply very quickly and in the shortest possible time are able to double their mass, while mucus appears on the walls of the tank and on other aquatic plants, all this is accompanied by a pungent unpleasant odor.

Aquariums often suffer from nitchaka, a dark green, almost black algae that braids aquatic plants, preventing light from reaching them. As a result, they cannot fully grow and develop, in addition, small fish get tangled in threads and die. Hydrogen peroxide has worked very well against blue-white algae and nitchan. To combat “uninvited guests”, a solution is poured into the water at the rate of 2.5 ml per 10 liters of liquid, the procedure is repeated daily until the algae are completely destroyed, most often the effect is noticeable already on the third day.

Vietnamese is considered a very dangerous seaweed. If she entangled the plant, the treatment will have to be carried out in a separate tank, since only increased concentrations of the reagent will help here. The affected plant is carefully removed from the soil and placed in a jar with a peroxide solution, in this case the dosage is 4 mg per 10 liters.

Processing is carried out for about an hour, then the plant is returned back to the aquarium without rinsing. To achieve the effect, peroxide is introduced into the water at a standard concentration. A danger to plants is the “black beard” algae. The leaves become covered with a dark bloom and gradually die, a similar phenomenon occurs with a large amount of food residues in the water and excessive aeration. Hydrogen peroxide is one of the most effective remedies against this algae; the treatment is carried out in a concentration of 2–2.5 ml per 10 liters of water every day until the aquarium is completely emptied.

General terms of use

Immediately, we note that a 3% solution of hydrogen peroxide is used in the aquarium. The composition has established itself as an effective remedy that can fight many diseases, oxygen starvation of aquarium inhabitants, as well as rapidly growing algae. Do not forget that this drug is very strong and aggressive, therefore, if the recommended concentrations are exceeded, it can simply burn out all living things in an artificial reservoir.

To avoid such unfavorable consequences and, instead of treating the fish, not to destroy them completely, peroxide is first diluted in a separate container and only then poured into the water. Usually, before use, it is diluted 10–20 times, and then very slowly, using a syringe, is introduced into the filter stream. After 60–90 minutes, you should change the water halfway. otherwise, organic matter dying off under the action of the drug will start to rot and poison the water.

Emergency situations

Hydrogen peroxide is used to disinfect a liquid when an excess amount of organic matter has accumulated in it, which may be the result of the following reasons:

  • Overfeeding of the inhabitants leaves uneaten food residues in the water, which, decomposing, pollute the aquarium;
  • If the breeder accidentally poured too much feed and did not immediately remove the excess;
  • If one or more fish die. if not removed in time, they will begin to decompose and release toxic substances into the water;
  • If the filter breaks.

Important! In this situation, first you need to eliminate the source of pollution, replace the water by 30-50%, and then add the reagent at the rate of 1.5-2 mg for every 10 liters of water.

In addition to the cases described above, hydrogen peroxide is also used for the incubation of eggs. peroxide contributes to the maximum yield of fry and their better development. Many arthropod lovers add a solution for brine shrimp. for faster hatching, they are immersed in the drug solution for half an hour.

For the dosage of hydrogen peroxide required for the aquarium, see the following.

Fish treatment

For the treatment of fish, hydrogen peroxide is used in two cases:

  • Resuscitation of fish suffocated in sour water, water with ammonia or with an increased concentration of carbon dioxide;
  • Bacterial infections on the body or fins. mainly fin rot, as well as external protozoa or parasitic infections.

In the first case, peroxide (we are talking about a pharmacy 3% solution) is added at the rate of 1-3 ml per 10 liters, it makes it easier for fish to breathe, saturating the water with oxygen, and accelerates the oxidation of ammonia, thereby reducing its concentration.

In the second case, the concentration of the substance should be 2.5 ml per 10 liters of water, peroxide is added to the aquarium once or twice a day, the total treatment time is from 7 to 14 days. You can use short-term baths with a concentration of up to 10 ml per 10 liters of water.

However, in my opinion, in this case, using H2O2 not entirely justified and effective. Fin rot and ichthyophthyriosis can be treated quite easily with more gentle drugs (and the former is sometimes just by raising the temperature and improving the quality of the water).

Hydrogen peroxide: disinfection of the aquarium

In high concentration H2O2 is a good disinfectant. Kills all microflora, while after treatment, no thorough flushing is required (as, for example, after the use of chlorine-containing agents), since it decomposes into safe oxygen and hydrogen.

Disinfection with hydrogen peroxide can be used after an outbreak of infectious diseases, as well as if the aquarium is attacked by hydras, planarians, or if small snails have disastrously bred in it.

For disinfection, all living things (what we want to preserve) are removed from the aquarium. fish, invertebrates, plants. The soil and equipment can be left inside, in which case it will also undergo disinfection.

30-40% perhydrol is poured into the aquarium (not a pharmacy 3%, but a highly concentrated industrial solution of hydrogen peroxide), which is then diluted with water so that the concentration is 4-6%.

After processing, the liquid is drained, the aquarium is rinsed with clean water, if there was soil, it is carefully siphoned off the remnants of dead organic matter, after which the bank is ready for use. Nothing alive in her anymore.

If you need to remove planarian and hydras without restarting the aquarium, this can be done in an existing container by adding a pharmacy solution to a concentration of 4 ml per 10 l of water.

Is hydrogen peroxide harmful to plants, fish and biofilter bacteria??

In order not to damage the plants, peroxide should be added in a dosage of no more than 2.5 ml per 10 liters of aquarium volume per day. Stiff-leaved plants such as anubias tolerate it better than others (up to 5 ml per 10 l).

Poorly tolerated H2O2 vallisneria (practically soluble in water), lomariopsis, some mosses, ludwigia, hornwort, kabomba and other long-stemmed plants with pinnate or needle-like leaves.

Fish (as well as snails and shrimps) usually tolerate the use of hydrogen peroxide calmly if its dose does not exceed 4 ml per 10 liters of water and if the animal does not get a concentrated solution.

The same can be said for the nitrifying bacteria in the biofilter. Even if part of their colony suffers from the harsh effects of atomic oxygen, it will quickly recover.

Hydrogen peroxide against algae

It is used for the destruction of blue-green algae, when it is necessary to urgently and ruthlessly suppress their outbreak, green unicellular (euglena), causing water bloom, as well as in the fight against Vietnamese and black beard.

Contribute in a dosage of 2-2.5 ml per 10 liters of water every day for a week. It is better to inject the solution from a syringe, trying to get it onto the algae accumulations. The effect of application usually begins to appear on the third day.

To get rid of flip flops and a beard growing on the leaves of hard-leaved slow-growing plants, you can soak greens for half an hour or an hour in a separate bath with a peroxide solution (concentration 4-4.5 ml per 10 l).

It seems to me that the method has the right to exist only in relation to blue-green algae, and then only as part of a complex therapy.

To combat euglena, a UV sterilizer helps much better, darkening the aquarium and introducing a culture of daphnia into it.

Hydrogen peroxide for the aquarium: benefit or harm

Now, when every self-respecting aquarist has a cherished shelf with aquarium chemistry. water conditioners, medicines for fish, disinfectants and others. it is somehow strange to talk about using simple pharmaceutical products in an aquarium. Such as, for example, hydrogen peroxide. But let’s still first figure out what role this substance can play in the life of an aquarium, and then decide whether we need it or not.

Operating principle

The main functions of hydrogen peroxide (H2O2) two:

  • Saturation of water with oxygen (since in water it decomposes into hydrogen and oxygen);
  • Oxidation of organic matter, including the components of living cells of lower organisms (bacteria, algae, polyps and others), which are undesirable or harmful in the aquarium (this effect is fatal for them).

Let’s talk about how to work with H2O2 in aquarium. It must be added to the specified concentration, diluted in advance with water in a jar or syringe about 10-20 times.

From a can or syringe, slowly pour the diluted solution into the filter stream.

After half an hour or an hour, it is necessary to carry out a partial water change (30-50%) with a soil siphon, since after using this substance in the aquarium there is a large amount of dead organic matter (dead algae, bacteria, protozoa), which can begin to rot.

So, in what situations can hydrogen peroxide be used??

Hydrogen peroxide in an aquarium in an emergency

This refers to situations where there is unexpectedly too much organic matter in the aquarium water, for example:

  • A whole jar of food was accidentally overturned there and for some reason was not immediately removed (this usually happens when a child fed the fish, did not manage, and was afraid to tell his parents);
  • Or if a large fish died, was not noticed in time and began to decompose;
  • Or the filters were turned off for a long time (several hours), and then turned on and released a huge amount of dead bacteria into the water.

In these cases, after removing the source of water pollution and making a partial change, turn on aeration to the maximum and add 1-2.5 ml of peroxide per 10 liters to the water.

Other uses H2O2

In addition to these purposes, hydrogen peroxide is sometimes used for:

  • Enriching the aquarium water with oxygen as a temporary preventive measure, for example, in case of a forced increase in fish stocking density, when the aerator or compressor does not cope;
  • Incubation of brine shrimp eggs for friendly hatching of nauplii. before being placed in the incubator, they are poured with a pharmaceutical solution of peroxide for half an hour;
  • Oxygen enrichment for the incubation of fish eggs and better development of fry. in special incubators and fry, where there are no living plants.

So, the use of hydrogen peroxide in our age of high technologies is quite justified. Although it should still be considered as an emergency aid in emergencies, and not as a drug for the constant maintenance of the aquarium.

For ear pain

Hydrogen peroxide has healing properties for the ears, it has a beneficial effect on otitis media. It is necessary to instill 4 drops of 3% peroxide in each auricle, the benefit will be that the remedy will eliminate inflammation and relieve pain.

The benefits and harms of hydrogen peroxide is a hotly debated issue. To understand whether it is possible to apply the agent inside, or it is better to use it only externally, you should study all the properties and features.

Gargling with sore throat

Hydrogen peroxide is used for medicinal purposes for angina. add a small spoonful of solution to 3 large tablespoons of water. The resulting mixture is gargled three or four times a day, at intervals of 3-4 hours. The antiseptic properties of peroxide quickly relieve inflammation and eliminate infection.

Body cleansing

Hydrogen peroxide is beneficial for cleansing the body, when taken internally, the solution helps to quickly remove toxins, urea and ammonia compounds. The tool brings a good effect with an excess of toxins, the beneficial properties are clearly manifested after alcohol poisoning. A useful solution helps to quickly cope with the effects of libation, relieves the body of harmful substances and eliminates increased heart rate, tremors and nausea.

What does hydrogen peroxide cure?

The healing properties of hydrogen peroxide are used to treat the following ailments:

  • Infectious and colds. flu and sore throat, colds and bronchitis, tracheitis and pneumonia;
  • Diseases of the nose and ears. runny nose, otitis media, sinusitis;
  • Dental diseases. caries and periodontal disease;
  • Neurological ailments. multiple sclerosis in the elderly, osteochondrosis;
  • Heart ailments. the solution can help in the treatment of the consequences of heart attacks and strokes, has a beneficial effect on atherosclerosis and varicose veins;
  • Skin conditions. from dermatitis to eczema.

For toothache

The benefits of hydrogen peroxide for teeth are expressed in disinfecting and mild analgesic properties. A couple of hydroperitic tablets are diluted in 100 ml of water and thoroughly rinsed with the agent for several minutes. It is better to repeat the procedure several times a day. this will bring quick results.

For teeth whitening

With a useful solution, you can remove strong plaque. the brush must be dipped in peroxide and the usual procedure for brushing your teeth. Another way is to add 1-2 drops of the solution to the toothpaste.

From sinusitis

With chronic rhinitis and sinusitis, it is useful to rinse with a solution, the substance removes the inflammatory process and eliminates bacteria. About 15 drops should be diluted in a tablespoon of water and, using a pipette, briefly drip peroxide into the nose with a pipette, and then cleanse the sinuses.

The harm of hydrogen peroxide

When using a medicinal solution, and especially for internal use, it is important to remember about the minimum dosages of the beneficial substance. When consumed in excess, peroxide causes colossal harm. It can lead not only to nausea, vomiting and heartburn, but also to the appearance of ulcers and erosions in the stomach and intestines, to blockage of blood vessels and general poisoning of the body.

If an overdose does occur, and the solution has entered the body in too large quantities, you should immediately seek medical help. As an emergency, it is recommended to drink as much water as possible to reduce the concentration of the solution in the body. But in this case, it is not necessary to provoke vomiting, with the reverse movement along the esophagus, peroxide can cause even more harm.

Emergency help

It is not uncommon that a situation arises in which an overabundance of organic matter appears in the aquarium, for example:

  • An accidentally overturned food can;
  • A fish that died and was not noticed in time, which begins to decompose;
  • Disabling the filtration system for a long time.

The decomposition of organic matter interferes with the normal life of fish and plants. The water is polluted and the inhabitants of the “water house” may die.

In this case, treatment of the aquarium with hydrogen peroxide is simply necessary. What should be done? First of all, it is necessary to remove the source of pollution, and replace part of the water. Next, you need to turn on enhanced aeration and add the drug in the following dosage: 10.25 ml per 100 liters of water.

How much hydrogen peroxide to add to the aquarium?

Hydrogen peroxide. An easily accessible and essential tool for solving many problems in the aquarium. It will help to disinfect and oxygenate the water, cure fish and get rid of excess vegetation. However, hydrogen peroxide should be added to the aquarium in a certain proportion, otherwise the substance can cause great harm to fish and plants.

Operating principle

What happens after the hydrogen peroxide enters the aquarium? Let’s figure it out.

The drug, getting into the water, decomposes into hydrogen and oxygen, thereby enriching the stagnant aquarium. The oxidation reaction that accompanies the interaction of peroxide with the cells of lower organisms contributes to the destruction of unwanted flora, including blue-green algae. When adding reagent, small bubbles appear, which rise up.

Conclusion

Hydrogen peroxide. An environmentally friendly product and a great helper in the fight against pollution of the aquarium, algae and fish diseases. One of the main advantages of the drug is its effectiveness, availability and inexpensive price.

Of course, it makes no sense to use this tool all the time, however, in emergency situations, when you urgently need to remove algae, cure fish or destroy a large amount of organic matter, Hydrogen peroxide will show very decent results.

When carrying out the disinfection and treatment procedure, turn off the lighting and the filtration system. Since the drug loses its properties in the light, and the included filters will reduce its concentration.

It is very important to remember that Hydrogen Peroxide for fish and aquarium treatment must be diluted with water before adding. This will make it possible to avoid the death of fish and harm to ornamental plants, which can get the product in a high dose.

For what purposes can be used

Hydrogen peroxide can be used to:

  • Disinfection of the aquarium;
  • Destruction of unwanted vegetation and microorganisms;
  • Treating fish.

With insufficient aeration (air saturation) of the aquarium, with a sharp increase in water temperature, the fish lack oxygen, and they begin to suffocate. Hydrogen peroxide in this case. “Life buoy” for aquarium inhabitants. Usually, the result of using the product will be visible in 15.20 minutes, the fish quickly come to their senses and leave the surface to the center of their home. However, if hypoxia (lack of oxygen) lasts a long time, the drug may be useless.

Another use case. This is to use hydrogen peroxide in the aquarium against algae. Blue-green algae or slimy colonies of cyanobacteria most often appear in containers with reduced oxygen. They multiply instantly and can double their mass in a very short period of time, while mucus appears on the walls and on other plants. All this is accompanied by a rather unpleasant smell.

Thread. Filaments from green to almost black, growing anywhere in the aquarium, they entwine plants, stopping access to light, which prevents them from growing and developing normally. Small fish can become entangled in the threads and die. Hydrogen peroxide is considered an excellent remedy for filamentous.

Also, the drug helps with compsopogon (black beard), which covers not only filter elements and decorative attributes of the aquarium, but also plant leaves with a black bloom, gradually destroying them. Compsopogon growth can be caused by increased aeration or large amounts of uneaten food. If you miss the moment when the black beard begins to actively conquer the space of the aquarium, it will be very difficult to remove it.

Hydrogen peroxide. A proven remedy against cladophora, a filamentous algae that quickly loses its decorative effect in an aquarium. over, its spherical shape, gets along well with other plants and fish.

It should be noted that the treatment of aquarium plants with hydrogen peroxide can cause the death of some species. It has been noticed that ornamental algae with thin leaves can react negatively to the addition of hydrogen peroxide to the aquarium. In this case, it is recommended to reduce the dosage of the agent or replace it with an analogue.

Hydrogen peroxide will help stop reproduction and completely destroy hydras and planarians. However, in this situation, when carrying out the procedure, it is recommended to plant fish and algae in another container.

Features:

To preserve long-stemmed plants, the dosage of hydrogen peroxide should not exceed 10 ml per 100 l.

When carrying out the disinfection procedure in an aquarium with fish, the permissible dose. 25 ml per 100 l.

How much hydrogen peroxide to add to the aquarium, an increased or standard amount, each aquarist decides for himself. However, for beginners, it is recommended to use the lowest possible dose and increase it as needed. Or put fish out of the aquarium.

When using hydrogen peroxide in an aquarium, lower the temperature to room temperature and turn off the light, as the product loses its properties in high light conditions and in warmth.

When disinfecting water, destroying unwanted vegetation and treating fish, it is very important to observe all precautions. Hydrogen peroxide should be kept away from eyes and foodways. Otherwise, irritation and burns of the mucous membrane, as well as severe poisoning, are possible. If more than 3 mg of the drug of 3% concentration is ingested, a lethal outcome is possible. For therapy, a set of measures is carried out to wash the stomach with sodium thiosulfate (0.5%) or sodium bicarbonate, as well as intravenous administration of sodium thiosulfate (30%) in a volume of up to 300 ml.

How to use

Hydrogen peroxide (3% solution) must be diluted to a concentration that will not harm its inhabitants before adding to the aquarium. Fish are very curious, they can swim right under the drops of the drug and get burned. The exception is a situation in which complete cleaning and disinfection is carried out with the eviction of all residents.

Filters must be turned off during the procedure.

The amount of Hydrogen Peroxide in your aquarium will depend on the problem you need to deal with.

To combat compsopogon, you can use a concentration of 1 ml per 4 liters of water. 15.20 minutes after adding the product, 25% of the water in the aquarium is changed. The procedure is carried out several times until the algae are completely destroyed. If necessary, you can not dilute the peroxide, but release it with a syringe directly to the places where the black beard accumulates.

To destroy the thread, add 2 ml of hydrogen peroxide to 4 liters of water and after 30 minutes change from 25 to 50% of the liquid in the aquarium.

For the destruction of cyanobacteria, 25 ml per 100 liters are used. The product should be applied three days in a row.

When fighting planarians and hydras, 40 ml of the drug is consumed per 100 liters of volume. The drug is applied daily during the week. It should be noted that at such a concentration, decorative thin-leaved plants can be damaged.

Therapy for a bacterial infection is carried out at a dosage of 25 ml of the drug per 100 liters of water, from one to two weeks.

For additional aeration of the aquarium and for easier breathing of the fish, add 1 to 3 ml of the product per 10 l.
