CO2 for aquarium do it yourself

Periodic carbon dioxide supply to the aquarium is necessary because as a result of filtration and aeration, the CO2 content in the water tends to zero. And in such conditions, algae in a fish house can die. You can create a system (or generator) of carbon dioxide with your own hands at home. It is not so difficult.

From school, anyone knows that carbon dioxide, the basis of photosynthesis, is absorbed by plants from the surrounding air. Due to this, in fact, the growth of terrestrial flora occurs. And in the natural aquatic environment the concentration of CO2 is sufficient for the development of aquatic plants.

The same conditions must be created in the aquarium, which is a closed tank. Creating a concentration of carbon dioxide ranging from 3 to 7 milligrams per liter of aqua is a necessary condition for aquarium plants to feel normal. To do this, it is not necessary to acquire industrial carbon dioxide systems.

Drinking sparkling water as a source of carbon dioxide

It is so elementary that many aquarists do not even consider this method of introducing CO2 into aqua. And it is absolutely in vain, by the way.

The usual soda sold everywhere contains a significant dose of carbon dioxide (up to 10,000 milligrams per liter in highly carbonated water).

After opening the bottle a lot of gas comes out instantly, but still a significant part of it remains in the drink - up to 1500 mg / liter.

If in the morning to bring in aquarium water just 20 milliliters of soda per 10 liters of water, then for the aquatic flora this will be enough.

The simplest way to supply carbon dioxide

The main element is a vessel (a two-liter plastic bottle, for example) with ordinary brew. Fermented raw materials are poured into the bottle:

  • sugar - 300 g;
  • yeast - 0.3 g

The raw material is filled with 1 liter of water, sugar is not stirred. A tube (hose) is inserted into the bottle cap at one end, and the other end of the tube is lowered into the aquarium water. With the start of the fermentation process, the released carbon dioxide is discharged to the aqua.

To prevent clot mixtures from entering the aquarium, a small plastic bottle can be tied to the main tank and 2 more tubes can be attached so that the gas and fermentation products first fall into the small tank and only then into the aquarium.

This method has significant drawbacks:

  • the inability to adjust the amount of carbon dioxide supplied to the aquarium water and the instability of its supply;
  • the short duration of such a system is up to 2 weeks.

Do-it-yourself CO2 generator

For the manufacture of a working gas generator with adjustable flow will require a little more materials and labor.

The principle of the installation is the gradual supply of citric acid from one vessel to another, where there is baking soda. The acid is mixed with soda, and the CO2 released as a result of a chemical reaction enters the aquarium tank. Consider the manufacturing process of the stages of work.

Creation of the device

Take two identical liter plastic bottles. In the caps, you must carefully drill a hole through the tree through 2 holes for the subsequent installation of tubes (hoses). One tube with a check valve connects tank No. 1 with tank No. 2.

A tee tube is inserted into the second openings of the caps, one branch of which also has a check valve. Hoses with non-return valves should be inserted into tank No. 2, and a small tap for flow control is installed on the central branch of the tee.

Required reagents

A bottle of soda water is poured into bottle No. 1 (60 g of soda per 100 g of water), and bottle No. 2 is filled with citric acid solution (50 g of acid per 100 g of water). Lids with tubes should be tightly screwed onto the bottle.

All joints and openings must be reliably sealed with resin or silicone to prevent gas leakage. The ends of the first hose must be lowered into the solutions, and the left and right tee tubes must be installed above the level of the solutions — CO2 will pass through them.

Beginning of work

To start the process of generating gas, you need to press on the bottle number 2 (with citric acid). Acid through the first hose enters the soda solution, and the reaction occurs with the release of carbon dioxide. Nozzle check valve prevents soda solution under pressure from entering tank No. 2.

The released gas passes in two directions:

  • in a bottle of citric acid, creating pressure for continuous generation,
  • in the central pipe tee, through which CO2 enters the aquarium.

By means of the faucet it is possible to regulate the gas flow. If instead of a self-made tee to use hoses from a medical dropper, then an additional counter of gas bubbles will appear, which is very convenient for creating an accurate concentration of CO2 in aquarium water.

Alternative installations

There are also ways to supply CO2 from special gas cylinders or using fire extinguishers. Individual craftsmen implement such methods.

The nutrition of aquatic flora with carbon dioxide is the key to their normal growth and life. To ensure this process at home, a minimum of available material is enough, a bit of perseverance and very little financial expenses.

CO2 for the aquarium do-it-yourself supply of carbon dioxide, carbon dioxide into the aquarium


CO2 for aquarium ways to enrich the aquarium water with carbon dioxide gas, brew, recipes, do-it-yourself assembly, useful tips, recommendations, photo-video assembly of the mash Sooner or later, any aquarist is faced with the issue of supplying CO2 (carbon dioxide) to his water body.
On the Internet you can find many articles and forums on this topic, but all of them are narrowly specific - devoted to one of the issues related to CO2. Therefore, in this article I would like to put everything together, to present the material in an easy way, focusing on those methods and methods of supplying CO2 to the aquarium that do not require cash infusions and for which only your skills and efforts are necessary. So, first things first ...
What is CO2, why is CO2 needed for an aquarium?
CO2 is a gas that is needed by aquarium plants equally, or even more, as oxygen. This is not surprising, because plants are 50% carbon. In natural - natural conditions, the concentration of CO2 in water ranges from 15-40 mg / l. But in the aquarium, this figure tends to zero, even though the fish and other inhabitants of the aquarium produce it in the process of life, but in very small quantities. The normal CO2 level in an aquarium should be 4-15 mg / l. (golden mean 5 mg / l.) What is actually achieved by the artificial supply of carbon dioxide in the aquarium. The very mechanism of CO2 consumption by plants is in the process of photosynthesis. In a nutshell, the process of photosynthesis can be described as follows: plants, when interacting with light, consume carbon dioxide and produce oxygen. From the above, we can conclude that the more CO2 there is, the more O2! What does this give? Everything is obvious:
- lush growth of plants - this time! Plants in the aquarium are beautiful and healthy, booming.
- the presence of oxygen from plants is two! Allocated additional oxygen is consumed by fish and other inhabitants of the aquarium, which can reduce the need for mechanical aeration of the aquarium, or even completely nullify it (but for this you need a lot of additional knowledge and fine-tune the aquarium's bio balance).
- in addition, using the supply of CO2 to the aquarium, you can lower the pH of the water, making it more acidic - that's three! What really like many fish. Cautions and dangers of CO2 in an aquarium!
It must be understood that carbon dioxide is not the only element involved and necessary for the growth of plants, as well as for the aquarium as a whole. On this occasion, you can give a good example: If a person breathes the purest oxygen, but does not eat, he will die.
Therefore, if we talk about aquarium plants,
then for them the formula for success is as follows: LIGHT + CO2 + FERTILIZER + TEMPERATURE At the same time, the loss of at least one element of the formula, entails the poor condition of the plants, and even death. A little more about each element: LIGHT. No matter how much CO2 in an aquarium, without light it will not enter the process of photosynthesis. Only a sufficient amount of light and CO2 favorably affect the plants and the aquarium !!! Otherwise, you just "choke" the fish! Lamp power in the aquarium is calculated based on the volume of the aquarium. For fluorescent lamps, it is 0.5-1 W per liter. FERTILIZER. Plants vital minerals, macro and micronutrients. Without them, their aquarium existence is fleeting.
TEMPERATURE. Each specific plant needs a certain temperature. And besides, the temperature affects the saturation of aquarium water CO2. The higher it is, the lower the concentration of carbon dioxide in the aquarium and vice versa.
So you can make CONCLUSION that: only the correct, balanced configuration of all components is GUARANTEE OF SUCCESS!
Otherwise, it will produce CO2 emissions - a glut of carbon dioxide and as a result, the death of aquatic organisms.
"The word hydrobionts is used because it is often found in articles on this topic and in aquaristics as a whole. The word is phillipsyvoe, but essentially means the totality of all fish, mollusks, aquarium plants, lower aquarium organisms." And one more warning: With the help of CO2, you can bring down the pH of the aquarium water (what is this pH read HERE). Small fluctuations in pH within 2 degrees during the day and at night are not terrible, but sudden drops are dangerous. Therefore, it is very important to monitor this parameter first and in case of anything, adjust the CO2 supply.
Additionally, I recommend that you read the article. AQUARIUM PLANTS: let's talk about the benefits of plants for your aquarium! You will find a lot of interesting things in it and you will learn about the life of aquarium plants.
BUT, back to CO2. So, we got the knowledge base. I think that you have put together your impression of the need for a CO2 system in an aquarium and you can safely answer the question - Is it possible to do without installing CO2 in an aquarium? It is possible, but not necessary !!!
Methods of carbon dioxide in the aquarium. Types of CO2 installations.
There are three ways or types of supplying carbon dioxide to an aquarium:
- MECHANICAL, it is balloon, it is the purchase method;
- CHEMICAL;
- INSTALLATIONS of FERMENTATION;
An article on this subject is HERE! There is also a table of CO2.
In short, we can say that MECHANICAL METHOD - This is the best way: go to the store to buy the installation and according to the instructions, you apply gas to the aquarium. But - it is expensive, cumbersome and again expensive! I do not think that for one home aquarium is worth cranking. Although if you are unlimited in money and are truly keen on aquarium plants, this way is for you!

The cost of balloon CO2 installation is $ 200
CHEMICAL:
mixing reagents receive the allocation of CO2, which is fed into the aquarium. This method is the place to be, but it is more complicated than the installation of fermentation. There are also “sales” CO2 tablets.
Cost $ 9, you need to constantly buy new ones
And so we got to the easiest, cheapest way of supplying CO2 to the aquarium - it is the INSTALLATION OF CONCRETE (synonyms: system, unit of CO2, mash, mash of CO2, etc.).

In my opinion - this is the most interesting and unobtrusive way of supplying gas to the aquarium. On the Internet, there are only two drawbacks to this fermentation system:
- suitable only for aquariums up to 100-120 liters;
- it is not possible to regulate the flow of gas (cut off at night);
However, what's stopping you to put two fermentation plants? Here you have the capture volume of aquarium in 200 liters. Regarding the second item, I do not see any problems pulling the CO2 sprayer out of the aquarium at night or making the CO2 release valve. In addition, it is worth noting that such a CO2 supply system by type of mash Navryatli will overpower the aquarium with carbon dioxide. She is weak! Well, and what's more, you always watch the aquarium and in the case of something bad you can always stop the process.
There are a great number of carbon units of CO2, they all sparkle with innovation and simplicity. There are even more recipes, ingredients for the fermentation system. Below, I will definitely list all the brewing brewing recipes for the aquarium known to me, but in the meantime I offer you a step-by-step, sensible CO2 system manual for the aquarium (with photos) that you can do with your own hands. Such installation will not require from you special knowledge and efforts, any specific details and will cost you a mere penny. That is why, I recommend it to you, moreover, in our opinion, such an installation is one of the safest self-made CO2 installations.
Ok so here's a list of that
WHAT NEED

A two-liter plastic bottle of mineral water or other beverage.
Used as a main container for the mash. It is better to use a transparent bottle, so you will see the process and in the case of "unauthorized situations" respond in time, although they are unlikely to occur, if done correctly.
Cost $ 1, empty $ 0 :)

A liter bottle of juice with a wide neck. For example, from under the juice "Biola". It is used as a kind of filter, so that the beer and the accompanying biaka do not get into the aquarium. Cost 1 $.

A bottle of sports water, or rather a cap from it. It will be needed to block the mash and create a gas bubble counter. Cost 1 $.

The syringe is pyatikubovy. Used as a bubble counter. The cost of a penny.

Dropper. Sold in any pharmacy. Need as hoses and connectors for a CO2 system. Cost 0.5 $.

Silicone "aquarium". Need for a better sealing unit. The cost of $ 1.

Backpressure valve 1pc., Can be 2pcs. Sold in any pet store, designed to block the mash, and also to ensure that the water from the aquarium does not flow into the system or on the floor. Cost $ 1-2 apiece.

Spray. Kameshkovy, a sprig of mountain ash, "CO2 bell" and so on. You can do without a spray gun - by connecting or sticking a tube with CO2 into the filter. Cost 0.5 $

Adapter triple, faucets. Not necessarily, but for those who are afraid of CO2 emissions need. Sold in a pet store. It is worth one 0.15 $.

Tube or hose aquarium. It is slightly thicker than dropper hoses, it may be necessary. Worth $ 0.3 per meter.
Suckers To attach shlag submission of CO2 in the aquarium.

TOTAL: cost of the CO2 brass system
will be released at 7-8 US dollars.

STEP BY ASSEMBLY
CO2 SYSTEMS FOR THE AQUARIUM We take the cap from the sports bottle. Disconnect the white cap.

Knife cut, scraped partitions in the red part of the cap. Try to do it carefully and so that there are no tails left. Leave aside.


Take the syringe. Remove the piston. Cut off the bottom of the syringe.

We insert a back pressure valve into the syringe so that nothing flows from the syringe and the air passes into it. Check !!!


Insert the syringe into the prepared red cap from under the sports bottle as follows. The cap can be requested (optional). Fill the syringe with water. It turns out the bubble counter. With the help of it, you can determine the intensity of the gas supply to the aquarium by leaving bubbles. (it is convenient to pour water using another syringe with a needle)


Ready-made "cover-valve-counter" is screwed on a two liter bottle. Leave aside.

We take a drip. Disconnect the adapter. Immediately can be removed from the dropper supply controller. He will not need. So, if you block it, the mash will burst.


Disconnected perkhodnichok leave.
We make a hole under it in the lid from under the "Biola".

Insert the adapter into the cover.


Nearby we pierce a cover from under "Biola" with a needle from a dropper.
Make sure the needle does not clog with plastic caps.


From the bottom of the lid into the peredelok we insert the spl from the dropper to the bottom of the bottle "Biola" - to the bottom.

All adapters need to be sealed from two sides (tightness of the filter, after drying of the silicone, you can check by lowering it with water and blowing it). Fill the resulting filter with water. Like that.

We connect everything! With the help of dropper hoses.
Note!!! What is the main part of the hose goes to the filter valve with a tube, and from the needle goes the hose to the aquarium with a spray.

CO2 system for aquarium is ready !!! You can carry it to the aquarium.
For those, it is afraid of an overdose of CO2 in the aquarium and does not want to constantly get a sprayer. Additionally, a “trigger valve” can be incorporated into the above construction. You can insert this fragment anywhere in the system.

TRANSFER TO RECIPES
Brags for the Aquarium
Each aquarist individually selects a recipe for home brew, modernizes and varies it to fit his needs. Here is one of the common recipes - the so-called "slow mash" recipe. Works up to 3-4 weeks.
Take 150 grams of sugar. Fall asleep in a two-liter brago.

Add a quarter of a teaspoon of soda.

A little fish food

A teaspoon of fertilizer for plants.

Slice of bread.

Add the yeast. A bit - 1/4 teaspoon.
You can pre-dissolve.


Fill bragotaru with water. Оставляя 4-6 см. до горлышка. Воду заливаем кипяченую (не горячую) или отфильтрованную. Я беру воду из аквариума, ниже объясню почему. После того как все ингредиенты залиты водой мешать болтать их не стоит, так брага быстрее "выдохнется". Для ускорения процесса старта работы браги дополнительно можно развести 40-50 грамм сахара в стаканчике с теплой водой, до получения сиропа. В другом стаканчике развести ? чайной ложки дрожжей. После вылить и смешать с сиропом.Pour the obtained into the bragotar (observing the distance from the neck 4-6 cm.). I recommend to do this for the first time, so as not to wait a long time for the result - when will the brag work. We close the container, cork the entire system,
drop the sprayer into the aquarium and wait for the reaction and CO2;)


The reaction and CO2 gas will go in about 8-12 hours. If up to 24 hours the gases do not go, then something is wrong - either the system is poisoning it, or something is wrong with the reagents. Check the tightness of the installation or add sugar and yeast.

Now I would like to, before giving the other recipes, talk about all the ingredients of home brew separately.
In fact, in order for the brew to work, you need sugar, yeast and water. All the rest is innovation and yeast auxiliary components.
SUGAR. You can use any, but they say that the cane is the best. The more sugar there is, the more yeast bacteria will eat. The more alcohol and CO2 will be released.
YEAST. There are bread (dry and "wet"), you can use those and those! Almost no difference. Recommend dry. There are also beer and fodder yeast. For co2 systems recommend beer.
WATER. It is necessary to clean, so that yeast bacteria do not fight with other competing "comrades", as well as bleach and other impurities. I use aquarium water for the brew; in it all the harmful substances have already disintegrated and it is most suitable for fermentation.
The remaining items are:
Soda need to neutralize acids. Makes the mash more alkaline, which prolongs its viability. Soda can not be used - this is an additional element.
Fish food and fertilizer for plants. They participate in the fermentation process - by stimulating it and feeding the yeast bacteria.
Slice of bread - also improves the fermentation process. Some throw instead of him two raisins, dried apricots and others.
AFTER HAVE DRAWN IT, RECOMMEND TO DRAIN 2/3. THE REMAINING PART IS DOWNLOADED WITH NEW INGREDIENTS.
Other CO2 recipes of the type "mash": Sugar - 40 tablespoons;
Starch - 16 tablespoons;
Soda - 13 tablespoons;
Water - 2 liters;
All ingredients are cooked in a saucepan until thickened. After it is cooled and poured into a five liter container, add 1 tablespoon of dissolved yeast to a glass of water. Performance 3 months.
Sugar -150 grams;
1 teaspoon yeast;
2 teaspoons of soda;
2 tablespoons of flour;
1.5 liters of water .;
2 l. bottle;
Efficiency 1-1.5 weeks.
10 gr. citric acid;
10 gr. drinking soda;
The ingredients are mixed in a dry state, poured into a moist (without water) bragotar. Tara sealed. Works 6-10 hours (for the whole daylight hours).
On a two-liter bottle:
Sugar 3 cups;
30 grams of gelatin;
1n l. water;
1 tbsp. drinking soda;
1 tsp of yeast;
Gelatin is soaked for one hour in 0.5 liters. water. Then add another 0.5 liters of water, add sugar, soda. Heat over low heat until completely dissolved. After cooling, the "jelly" is poured into bragohra, dissolved yeast is added on top (without stirring). Efficiency 2-4 weeks.
5 tbsp. spoons of sugar;
2 tbsp. spoons of starch;
1 tbsp. spoon of soda; ? liter of water;
1 tsp of yeast;
Dissolve sugar, soda and starch in water. Put in a water bath until thick. Next, pour over the yeast, dissolved in a glass of water. Efficiency 2-4 weeks or more, if you put more starch.
I hope there are enough recipes !!! Offer your own.
Now let's discuss how to correctly CO2 in the aquarium. Carbon dioxide should be fed into the aquarium using a spray: stone, rowan sprigs, bells, and also directly attach or insert the CO2 tube into the filter with aeration. Which sprayer is better, which one to use? Choose you based on your CO2 needs.
Stone spray. Sold in any pet store. The disadvantage is that CO2 bubbles are not very small (they will be less soluble in water).
A sprig of mountain ash. Gives small bubbles, but quickly clogged.
Bell. Purchased or homemade. A cap-dome, delaying the supplied CO2.
You can combine sprayers. For example, put a dome over a stone sprayer. Bubbles reaching the surface will linger in the dome.
Where to put a CO2 sprayer in an aquarium? It is also up to you to decide, it is better to set it so that it spreads in a stream of water.
Here, by the way, a good video on the assembly of CO2 for the aquarium And finally, I wanted to talk about
RESULTS AND SIGNS OF NORMAL CO2 WORK.
- after installing CO2, after about a week, aquarium plants should be covered / bubbled with oxygen. Observed active growth of plants.
- Fish should feel great. In case of worsening of the state of health of the fish, they are deposited for 2 hours in clean water (brought to their senses). CO2 off. Restarting the adjusted CO2 is fed in 3-7 days.
- the appearance of algae - a sign of CO2 emissions. It is necessary to reduce the supply of carbon dioxide.
- if the pH has collapsed. One dissolved teaspoon of baking soda will raise it by 4 degrees (in a volume of 50 l. Of water).
- if a gray bloom (film) appeared on the spray gun - it is not scary. These are organisms associated with fermentation, they do not harm the aquarium. But it is better to wash the sprayer.
- How to make sure the normal level of CO2 consumption by plants. Buy and make a pH test in the morning before turning on the light and the second in the evening. Compare the results and decide whether everything is normal.
I WISH YOU SUCCESS!
