How to lower the ph in the aquarium :: aquarium water ph :: Aquarium fish

The effect of acid-base balance on aquarium vegetation and fish

pH is an indicator of the acidity of the solution, characterizing the concentration of hydrogen ions. The pH of the “neutral” solution, that is, where the concentration of hydrogen ions H + and hydroxyl ions OH- is almost the same and “balances” each other, is 7.0. Typically, the pH of drinking water is close to the neutral index, that is, to 7.0. But sometimes there is a situation when it should be lowered.

For example, in everyday life this may be necessary if the fish in an aquarium need a more “sour” environment. How can I lower the pH of the water?

The question “And yet! What appeared first? Egg or chicken? “- 12 answers

  • – strips of indicator paper;
  • – acidified water;
  • – buffer soil;
  • – carbon dioxide;
  • – a piece of wood.

1. First of all, try to find out exactly what level of pH your pet needs for normal well-being and vital activity. It depends primarily on the type of aquarium inhabitants.

You can use special literature for aquarists, search for information on the Internet or ask a specialist to ask a question (for example, in a pet store).

2. Purchase strips of indicator paper in specialized stores. Of course, they give only a “rough”, very approximate estimate of the pH value, therefore it is better to measure its level using a special device – a pH meter.

Such devices are practically in any laboratory.

3. You can lower the pH of the aquarium water, adding to it exactly the calculated amount water with a lower pH (acidified). Orthophosphoric acid is commonly used as an acidulant reagent.

It is better to add such water in small portions, mix thoroughly and make control measurements of the resulting pH level. Otherwise, it is easy to lower the pH to values ​​harmful to the fish.

4. In some pet stores there is a special buffer soil on sale. When it is placed in water, the pH level gradually decreases.

It also requires constant monitoring.

5. A good way is to introduce carbon dioxide into the aquarium water. This can be done with the help of special devices or cartridges where carbon dioxide is under pressure.

6. Sometimes a simple but effective method will help. In the aquarium after pre-treatment, put a piece of wood. What kind of tree is suitable for this, what processing it will require – find out from a specialist.

You will immediately solve two problems: lower the pH water, and your aquarium will acquire a new decoration.

The topic of phytoterpies in an aquarium – the use of various leaves, bark, charges and decoctions is not new in aquarium and on the Internet a lot of things have been written about this. On our resource, there is also a fairly extensive forum thread. Leaves of oak, almond, alder cones in an aquarium and an article about it Herbal medicine for fish and aquarium.

But, still and again I want to spend time and talk about the benefits of tea!

The motive for writing this article was the frequent appeals of forum users with almost a plea for emergency help to save the fish! When you enter into correspondence with a user, it turns out that he has no idea about the aquarium life, there are no preparations in the yard, as luck would have it at 3 am))).

And then there is a dilemma – you need to help a person, but how? I usually say: “You have to understand this and that … I give the links, read this … buy it tomorrow and apply it … if the fish suffocates, add hydrogen peroxide etc.”.

But, alas, as a rule, the fish die in the morning, the links remain unread, the user disappears … But the most amazing thing is that time passes and the same user again refers to the forum with the same problem.

The second motive for the “tea discussion” was different opinions about the effectiveness and benefits of tea! Well, let’s dot the Ї.

So, what makes tea with aquarium water? And he does about the same as mother nature in the natural habitats of fish. Water in lakes, rivers and other bodies of water will fall from streams of forest that flow among the remains of dead plant matter (organic matter), flow through fallen leaves, mosses, and so on.

As a result, water is enriched with so-called tannins and humic acids – organic compounds of dead organic matter. These substances have a beneficial effect on the health and well-being of fish.

You ask me, well, and where does tea? The fact is that tea, in some respects, replaces the entire complex process of enriching water in nature!

That is, it partially contains those beneficial organic compounds that fish receive under natural habitat conditions.

In order not to be unfounded, let’s look at what is contained in tea.

The substances that give tea useful and healing properties include:

– tannins (tannins);

– pigments and other groups;

Tannins (tannins). Actually these substances also give tea characteristic tart taste.

Their approximate content in the tea leaf is from 8% to 30%. They are a complex mixture of tannin and catechins, polyphenols and their derivatives.

In addition, caffeine in conjunction with tannins, as well as the tecatechins have the properties of vitamin P, which has a capillary strengthening, hypotensive effect, stabilizes the collagen of the vascular walls, promotes the best activity of vitamin C.

Essential oils. Contained in tea slightly (0.006% in dry tea leaves).

They act in a certain way on the central nervous system (especially on the limbic system).

Alkaloids. Caffeine is the main tea alkaloid. In tea, it is combined with tannins and forms theine.

Its content in tea is from 1% to 4%.

Vitamins. In certain quantities, almost all the essential vitamins are present in tea. The most basic are vitamins P, B, A, D, E, K. The tea also contains minerals, salts: iron, manganese, compounds of magnesium, sodium, silicon, potassium, calcium, etc.).

So, from the above, we can conclude unambiguously that tea can sometimes be used instead of expensive conditioners. Especially when there is nothing at hand.

Tea seems to “age” water, giving it beneficial properties.

What is useful tea for fish and aquarium?

Tea is effective for restoring the skin (wounds, cuts). It is effective in severe forms of ichthyophthyriosis (semolina fish), when the disease is accompanied by massive destruction of the skin epithelium. Even if we destroy the parasites with the help of drugs, there will be wounds on the body of the fish in those places where the ciliates “lived”.

What can fish do for sepsis or osmotic shock?

Tea is very useful in the treatment of fish with salt baths. Salt kills ectoparasites, but at the same time it strongly destroys the skin, which can be restored by tea brew.

Tea has a tanning, astringent, septic effect, from which wounds heal quickly.

Tea has a tonic effect. Thus, it can be used simply for the pleasure of the fish, or during treatment, to reduce stress, calm the nervous system, mitigate the negative effects of treatment.

Tea warnings!

Looking through the forum discussions about adding tea to the aquarium, one can always find diverse opinions. Some say tea is cool!

Others, on the contrary, say that all of this is a “filkina letter”. If you put all the opinions together, we get the following:

1. Tea is not a panacea. It can be considered as a useful conditioner – an additive that improves the quality of water.

2. Tea is not a medicine. Severe wounds, ichthyophthiriosis, fin rot other diseases cannot be cured by them.

Tea only contributes to the easy and rapid course of the disease. Tea helps well during the rehabilitation period after an illness.

3. It must always be remembered that tea “acidifies” water. Excessive, illiterate pouring of tea can lead to pH will collapse, from which hydrobionts will die. In a good way, you need to check the pH level with tests before adding the tea, and only then decide whether to pour the tea or not.

At the same time, in practice, it was noted that tea can be safely used in small quantities, approximately once or twice a month. Nothing will happen.

If, however, it so happened that you overdosed tea, which is primarily manifested in the strangulation of fish (fish swallow air, breathe heavily). You need to immediately replace some of the water with fresh water, increase the aeration and pour 20-30 ml from the syringe into the aquarium. hydrogen peroxide per 100l. water.

Fish will quickly come to their senses.

4. Despite the fact that tea is not a medicine, it still has a negative effect on pathogenic microorganisms, in particular on ichthyophtyrous ciliates. The fact is that the “more sour” water, the more difficult it is for an ichthic person to express himself.

As aquarists write, fish in acceptable acidic water never suffer from ichthyophthyriosis (decoy of fish).

5. Tea dosage. Different sources write different dosages and methods of making tea broth. Who writes that you can only use the third decoction, who offers one dose that the other.

You can read about all this in the above forum thread and the article on herbal medicine. I propose to withdraw some common qualifications based on my experience. I apply the first brew of tea and pour it into the aquarium before acquiring a pleasant, light, light yellow shade with aquarium water.

The dose depends on the type and quality of tea, if we talk about the dose, then for black tea, for 100l. (net volume) of the aquarium, I spent 40-70 ml. tea

6. You should know that green tea is more saturated with substances than black. It needs to be poured in smaller doses.

On this, perhaps, everything! Finally, I will only give examples of branded drugs, various brands that, one way or another, use “tea properties”.

That confirms its effectiveness.

Melafix API Melafix and Pimafix Pimafix

1% tea tree essential oil of the family Myrtaceae Melaleuca cajuputi Powell or Melaleuca leucadendron L. for Melaficca or 1% essential oil of clove pepper Pimenta racemosa (the Myrtaceae family) for Pimafica.

0.2% defoamer FG-10 Antifoam company Dow-Compliance Corporation. Midland, Michigan, USA, 97.8% of deionized water.

Tetra algumin

Mild biological remedy for algae control. Contains both humic acids, which create the beneficial effect of black water, and substances that protect water from algae.

Used when you have problems with algae.

Tetra torumin

Liquid conditioner, creating the effect of the so-called black water “, typical of the South American basin, which is customary for haracin, soft water cichlids, etc.

Water conditioner ToruMin is based on peat extract, contains tannins, humic acids and hormones. A beneficial effect on the natural behavior of fish and their color, improves plant growth.

The conditioner facilitates care of especially valuable, capricious breeds of fishes and creates conditions for their successful reproduction. With regular use of ToruMin, the light transmission of water decreases slightly, which stops the growth of algae.

Water acquires increased transparency and light brownish tint.

The same JBL pH minus is a natural oak extract)))
