How to make a CO2 production system for an aquarium with your own hands
We use a polyethylene container with a volume of 1.5 and 2 liters. In each case, the sizes of tanks may vary, depending on the volume of the aquarium and the amount of carbon dioxide required.
1. Pour into the container components: 5-6 tablespoons (with a slide) of sugar, one spoon of soda and 2-3 tablespoons of starch (also with a slide).
2. Pour 1.5-2 cups of water, as seen in the photo.
3. We send everything to the water bath.
Important: in the pan should be water almost at the level of the liquid in the bottles, otherwise the composition at the bottom will not become thick, and the top will remain liquid.
4. Cook to the consistency of thick kissel, that is, until cooked. You need to get a very thick mixture.
If to overturn a bottle, it almost should not flow down.
4. Cool the resulting mixture.
While the bottles are cooling down, we are engaged in the manufacture of hermetic and reliable caps with neat tube holders. After all, CO2 – what is it? This gas, and hence the sealing must be very thorough.
It is convenient to use fittings for the VAZ brake system (approximately 12 rubles / pair in auto parts stores). We will need two such fittings, gaskets and washers for 8 (about 40 rubles / pair of sets in OBI), as well as a pair of nuts for 8.
With a knife and a heated nail, you need to make a hole, then drive the thread down the nozzle into it (thread inside the bottle). Upstairs through the washer, and below the scheme: gasket / washer / nut.
There is no point in using various adhesives for sealing, as they will not provide the required protection. But the cover made according to the described scheme will reliably hold the tube, while the entire CO2 supply system will turn out to be quite resistant to manipulations and recharges.
After the bottles have cooled, you need to add to our jelly a teaspoon of yeast (dry), before carefully mixing them in water. For example, in a glass or glass.
The bottles prepared in this way are put in place, carefully connected and do not touch them for 3-4 months. Carbon dioxide is released evenly and slowly, and if low-flow “bell” type reactors are used, the whole process will be easily controlled visually.
When the level in the bottles drops below the middle, it’s time to recharge them.
Recharging is easy. The fermented mixture turns into liquid again and poured out, a new one is put in its place, and you again get CO2 for the aquarium.
With their own hands, the made device based on plastic bottles will easily survive many such recharges without losing their qualities. Gas is supplied around the clock.
- “Bell” – This is a reactor made on the principle of an inverted glass. Other types of reactors are not recommended to dissolve the mash, since the process of carbon dioxide emission will become uncontrollable, and the density of CO2 will be uneven.
- The simplest reactor of this type is single syringe, attached to the wall of the aquarium suction cup. Rewarded drinking bowls for birds also look quite aesthetically pleasing, and they are also inexpensive. There are many options: from a plastic cup, turned upside down, to complex structures.
The effectiveness of any reactor directly depends on the “contact spot” – the size of the area of contact between water and gas. Laffart advises for every 100 liters of water (hardness of 10 grams.) To make a dissolution area of 30 square meters cm.
It is not so much – only 5×6 cm.
So, there is a dilemma – to make a large reactor, or a small one, in which the dissolution process will be much better than in a large one.
This effect can be obtained by directing a part of the water along a thin tube from the filter under the flute to get a fountain inside the reactor. If you organize such flow through, for example, in a reactor from a syringe (20 cub.), Then the dissolution will improve several times, and the concentration of CO2 will be even.
And this is equivalent to the use of a “bell” type reactor, which has more bulky sizes.
CO2 – what is it? The use of CO2 in the aquarium. CO2 supply system
Sooner or later, every serious aquarist is faced with the issue of supplying CO2 to an aquarium. And not without reason.
Why does he need aquarium plants?
So CO2 – what is it? We all know that aquatic plants feed primarily on carbon dioxide dissolved in water. This is CO2.
In nature, plants get it from the pond in which they grow. Since the volume of water in natural water bodies is very large, its concentration in them is usually constant.
But about the aquariums can not be said.
The plants quickly use all the CO2 gas from the aquarium water, and by itself, its concentration will not be restored, because the aquarium is a closed system. Even the fish contained in it will not be able to compensate for the lack of CO2, as they exhale so small of its share that it will never be enough for plants.
As a result, aquarium plants stop growing.
In addition to the fact that plants stop growing due to a lack of CO2, water, in which its content is low, has an increased hardness (pH), which is detrimental to them. Even inexperienced aquarists have probably noticed that after adding plants, tap water becomes tougher than it was in an empty aquarium.
This is due to the fact that carbon dioxide contributes to the appearance of carbonic acid in water, and it lowers the rigidity. That is, it is important to understand: the less CO2 in water, the higher its pH.
There are several ways to solve the issue of supplying plants with CO2. You can install a special cylinder and the appropriate equipment, or you can go the other way and try to do everything you need with your own hands.
Many people like this method more. And it is clear why – after all, it is much more interesting and pleasant to solve the problem on your own, without resorting to the help of purchased equipment.
The only thing worth paying attention to is the result obtained. Not knowing how everything works in an aquarium, you should not go there and change something and redo it, so that you do not get upset.
What is important here is not participation, but an understanding of what you are doing.
Nowadays, more and more aquarists are engaged in the cultivation of aquatic plants and independently solve problems with a lack of carbon dioxide in the water. To some extent, such scales may well negate all the results of the control of harmful emissions from enterprises and automobiles, because home-made aquarium devices have become necessary and very fashionable, and their volumes are sometimes quite large.
Of course, this is a figurative comparison, but there is some truth in these fears.
So CO2 gas – what is it? How to deal with carbon dioxide in our aquarium and how to produce it inexpensively and in sufficient quantities?
But it’s quite realistic to make such a system by yourself and refill it 5-7 times a year.
Interestingly, when thinking about CO2, oxygen, light, and nutrients, they often forget about temperature. And it is the main regulator of aquarium photosynthesis.
Not light and not CO2, as it may seem. Botanists are well aware of this, but “aquarium researchers” often forget about this fact.
The regulatory role of waves such as infrared reflects precisely this function. Perhaps this is due to the fact that in the technology of manufacturing light sources used for aquariums, it is unprofitable to recall the temperature.
Therefore, they pretend that it is not important.
Aquarium may well do without fashionable and glamorous excesses. And not only can, but also safely costs.
The main thing is to balance the knowledge and cause-effect relationships obtained through research. If the system is already in balance, then you no longer need to touch it!
And do not try to fix something that works so well.
And nevertheless, if the aquarium tank is too densely planted with plants, then even with good lighting it can be enough for CO2. This is especially true for weakly alkaline hard water.
If there are combined species that can only assimilate non-occupied carbon dioxide (these are all types of mosses, many herbs that grow only in acidic and soft water, lobelia), and evriyonny and stenionionnyh species that are able to extract carbon from carbonates (and this , Elodea, Echinodorus, etc.), then the concentration of CO2 will be particularly low.
It is not at all difficult to cure, since it is enough to simply populate more fish into an aquarium. In those aquariums in which everything is normal with ecology, and with a dense population of animals, plants do not lack carbon dioxide even with quite a strong light.
But in any case, an additional dose of CO2 will not be superfluous for such a reservoir.
We examined in detail the role of CO2. What it is, is now also clearly understood.
It remains to learn how to produce it at home.
