Hydrogen peroxide in an aquarium in emergency situations

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

In high concentration of H2O2 is a good disinfectant. It kills the entire microflora, and after treatment, thorough rinsing is not 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 was attacked by hydras, planarians, or if small snails catastrophically proliferated in it.

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

30-40% perhydrol is poured into an 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 from the remains of dead organic matter, after which the bank is ready for use. There is nothing more alive in it.

If it is necessary to remove the planarium and the hydra without restarting the aquarium, this can be done in the existing tank by adding a pharmaceutical solution to a concentration of 4 ml per 10 liters of water.

Hydrogen peroxide in the aquarium: the dosage of algae and the treatment of fish

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 in 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 liters 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.

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

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 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;

A well-known and respected Petersburg aquarist V.Kovalev on the Living Water website tells very well about the benefits of hydrogen peroxide:

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 in 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 liters 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.

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.

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% solution of hydrogen peroxide.

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.

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

In practical aquarium fish farming, hydrogen peroxide brings its positive effects and is used in the following cases:

  1. Reviving choked fish – swimming (up to 4 ml. Of hydrogen peroxide per 10 liters of water, 2 ml is enough);
  2. Fish choking – adding a solution to the aquarium (10-20 ml. For every 100 l. Of aquarium water). This method is good when there is no possibility to start the compressor, and oxygen is urgently needed by the fish. The procedure is done no more than 1 time per day, and this takes into account the settlement of the aquarium: if the aquarium is overpopulated, you can slightly increase the dosage.
  3. Fight against unwanted animals in the aquarium (hydra, planaria) – up to 40 ml. for every 100 liters. aquarium water, make every day 1 time, the duration of the procedures 1 week or more. It is desirable to pre-remove the plants.
  4. Fighting protozoa and parasites – swimming for 5-15 minutes. (10 ml. Per 1 l. Of water). It is necessary to monitor the condition of the fish and, if necessary, shorten the bathing time.
  5. Bacterial infection on the body of the fish and its fins – bathing (2-3 ml per 10 l of water) – 2 times a day for 7-14 days.
  6. Fight against blue-green algae in an aquarium – add a solution to the aquarium (20-30 ml. Per 100 l. Of water). The effect is visible on the 3rd day.
  7. Combating algae on plants – bathing (4 ml. Per 10 liters of water) for 30-60 minutes. The method is applicable only to hard-leaved plants – it helps well in the fight against the filamentous alga “Vietnamese” (Latin. Compsopogon). [3]

It should not be forgotten that hydrogen peroxide is a very strong oxidizing agent, and in order to avoid burns on the body of fish and plants, it should be diluted with 10–20 parts of water before entering the aquarium and then brought into the aquarium and immediately before the filter outlet. When applying peroxide necessarily abundant aeration of water. It is not recommended to exceed the dosage of more than 4 ml.

3% hydrogen peroxide per 10 liters. water.
