Advice 1: How to saturate water with oxygen

Some aquarists have to address the question: how to provide fish with the necessary amount of oxygen? Especially in the warm season, when the rate of metabolic processes in the organisms inhabiting the aquarium, sharply increases and the concentration of dissolved oxygen in the water, on the contrary, drops sharply. Since fish do not have the ability to regulate their body temperature in warmer water accelerates their metabolism. How to saturate water with oxygen?

Instruction
1
First of all, make sure that in the aquarium in sufficient quantity was present to water the plants. A lot of them: various echinodorus, cryptocorynes, Elodea, rogolistnik, aponogeton, etc. of the Oxygen that they, as a rule, is enough to meet the needs of fish, even in the warm season, of course, provided that the inhabitants in the aquarium are relatively few. Note, however, that if plants will grow too densely, then there may be unpleasant side effects, they should from time to time to thin out.
2
If the plants in the aquarium for one reason or another, there are no (or very few), then it is necessary to resort to aeration, i.e. forced injection of air in water. You will need: compressor, rubber hoses and the tip of the spray gun. His task is to create output as many bubbles as possible, to increase the area of contact of the air with water ( so that more oxygen is passed into the water). Therefore, the tip is made of a material that contains many small pores.
3
Should provide the ability to adjust the amount of supplied air (e.g., during the cold period the fish requires much less oxygen for the reasons mentioned earlier). So either buy a compressor the capacity of which you can change or get the metal clamps (preferably the screw), with which you can "pinch" the hose, changing its cross section.
4
If you want to saturate with oxygen the aquarium with sea water, then one of the porous tip is not enough (especially when a large volume of the aquarium). In such cases, as a rule, use a narrow long tube-"column" with lots of small holes.

Advice 2: How to saturate the body with oxygen

According to the observations of scientists in the last 200 years, the proportion of oxygen in earth's atmosphere has declined by almost half, from 38% to 20%. Its lack is particularly acute in large cities with developed industry and busy traffic. To avoid hypoxia, experts recommend specially to enrich the body with oxygen, using not only fresh air but also modern technology.
How to saturate the body with oxygen
Instruction
1
To saturate the body with oxygen to a greater or lesser extent in several ways. The most effective and fastest of them – the so-called hyperbaric oxygen therapy, treatment with oxygen is fed under pressure into the pressure chamber. These sessions improve overall health, increase muscle tone and resistance to infection, help to resist stress. Find out if in your city the opportunity to undergo this treatment, consult your doctor. An alternative to the chamber can be a so-called oxygen capsule, which, along with equipment for sunbathing, often set in beauty salons. It not only helps to saturate the body with oxygen, but also has a strong cosmetic effect, as it is often used in combination with aromatherapy and color therapy.
2
Do some exercise, if you still haven't done yet. To cope with anoxia help classes and rhythmic breathing exercises, yoga, bodyflex. Daily outdoors, walk to and from work, go on nature weekend.
3
Take a course of oxygen therapy with the use of so-called oxygen cocktails, juices, who, with the help of a special device to turn into the oxygen-rich foam. According to doctors, half-liter serving of "Crema" on the efficiency effects on the body is two hours walk in the woods. It is worth noting that the attitude to this method is quite ambiguous. Skeptics argue that oxygenated only through the respiratory system, and not through the gastrointestinal tract. Whatever it was, if possible, this way it is worth trying: it's perfectly harmless, and is often recommended even for pregnant women, for whom oxygen starvation the most dangerous.
4
In recent years appeared in the sale of special mineral water enriched with oxygen. According to the advertisers, dissolved oxygen absorbs when eating. You may verify this assertion for yourself – in any case, the body will benefit at least from the quality of the water.
5
If possible, take a course of salon treatments, enriched with oxygen skin. The most popular of them – the so-called oxygen mesotherapy, in which aiming a jet of gas is applied to the skin from the apparatus through a special nozzle. This procedure rejuvenates and improves the appearance and speeds up the regeneration of the skin. Purchase a special oxygen cosmetics with anti-aging effect.
Note
The consequences of insufficient intake of oxygen can be very diverse: from headaches to depression. That is oxygen starvation leads to failures in work of separate bodies and organism systems as a whole, nervous, respiratory, immune. Ultimately, chronic hypoxia leads to premature aging. So do not neglect any opportunity to enrich your body with oxygen, using all means available for you.

Advice 3: How to release oxygen from water

Pure oxygen in large quantities is used in medicine, industry and other fields. For these purposes it is obtained from air by liquefaction of the latter. In the laboratory the gas can be obtained from the oxygenostergade compounds, including water.
How to release oxygen from water
You will need
  • - clean the tubes;
  • electrodes;
  • - DC generator.
Instruction
1
Before beginning the experiment, repeat safety. Strictly observe the rules of work with electrical appliances. Also, remember that the produced gases are flammable and explosive, therefore, require careful handling.
2
Repeat the concept of electrolysis. Remember that the cathode (negatively charged electrode) will undergo the process of electrochemical reduction. Consequently, there will be collected hydrogen. And at the anode (positively charged electrode) - the process of electrochemical oxidation. There would be atoms of oxygen. Write down the reaction equation: 2H2O → 2H2+О2Катод: 2H + 2e = H2 │2Анод: 2O – 4e = O2 │1
3
Prepare two electrodes. You can get them from copper or iron plates with a length of 10 cm and a width of about 2 cm Attach to them conductors of electric current.
4
Then in the pot, pour water and lower back electrodes. As a vessel for electrolysis use a deep mold or glass thick-walled, extending up.
5
Then take two clean test tubes and pour back the water. Close them with corks. Later open these vessels under water in electrolyzer and immediately put on the electrodes. Do this carefully so the water from the test tubes are not spilled. This is necessary in order to prevent air and in the process of electrolysis were clean gases.
6
Connect the DC generator. Turn it on when you know it's prepared correctly. Under the action of electric current on the electrodes will begin bubbling gases. Gradually the oxygen and hydrogen will fill the tubes, displacing the water.
Note
Keep in mind that according to the reaction equation of hydrogen will be collected two times more oxygen.
Useful advice
The electrodes can use thick nails, suitable in size to the vessels.
