Hello everyone, I am glad to see you again on my blog. Today, the theme of my post will be aeration of the aquarium. Since the purging of the reservoir with air is an old tradition that allows you to contain a much larger number of underwater inhabitants, you should understand the principles and essence of aeration of aquariums, whatever one may say.
Let’s start to deal with this issue.
We all remember from the school chemistry course that the air we breathe consists of two main gases: oxygen and nitrogen. In the aquarium environment, nitrogen is not used by underwater inhabitants and aquarium plants. He basically does not play any role in the course of various processes inside the aquarium.
However, oxygen occupies a special position in this situation. About the importance of oxygen, I already wrote in this article, you can find.
Here we will be somewhat in a different direction to deal with this issue.
Aquarium fish breathe oxygen, shellfish, and it is necessary for aquarium plants. Partially, a certain percentage of oxygen in aquarium water appears due to plant photosynthesis, which is produced during the daytime. Naturally, all living organisms breathe around the clock, they can not hold their breath.
At night, on the contrary, plants absorb oxygen and release carbon dioxide into the water. And if there are a lot of fish in your tank, an additional enrichment of water with oxygen is considered necessary.
I would also like to note one important point: the water temperature plays a strong influence on the concentration of oxygen in water. The higher the temperature, the less various gases can dissolve in it, naturally there will be less oxygen in such water.
The lower the water temperature, the greater the digestibility of gases and the higher the oxygen concentration in the aquarium water, which is vital for the respiration of fish.
Increased water temperature has another negative consequence: when the water temperature rises by 10 degrees, then in such water the flow of chemical reactions accelerates. A similar situation is in living organisms, as aquarium fish cannot adjust the body temperature by any means.
When the temperature rises in the fish, the metabolism increases, which leads to rapid breathing, and as a result – greater absorption of oxygen. And as you understand, its concentration begins to decline significantly.
If you have already sounded the alarm, then do not be in a hurry to be the bells, this problem can be solved as they say in a peaceful way – use aeration of the aquarium. Compressors can be used as air blowers in aquas. What he really is?
The device itself, to which the flexible hoses are connected, and sprayers of finely porous materials are installed at their end. Why small pores?
Because small air bubbles dissolve better in water while they rise to the surface than healthy bulbs.
Thanks to the finely porous tips, the aquarium water will be more saturated with oxygen. If desired, the flow of air bubbles can be adjusted as needed, increased or decreased. Usually, in summer, aeration of the aquarium is enhanced, since the water in the aquarium in summer can be very warm (more than 30 degrees).
And I already described the consequences of such a temperature a little higher.
It is believed that more attention in the aquarium should be paid to fish and not plants. There are several different views of people, I think you need to equally follow the optimal parameters of the environment for both fish and plants. In the saturation of water with oxygen by aeration, in addition to the positive aspects, there are also negative ones.
The fact is that if the aquarium has a high enough oxygen concentration, then there may be problems with mineral nutrition for plants.
As you know, oxygen is a strong oxidizing agent, which such important trace elements as: zinc, iron and manganese convert to a state in which aquarium plants cannot assimilate them. Moreover, when air bubbles rise to the surface of the aquarium, they absorb CO2, which also affects the plants, as they need carbon dioxide for photosynthesis during the daytime.
In general, in this matter, different opinions of aquarists who are engaged in breeding fish and growing plants.
I believe that in the daytime at any time of the year (except summer), the oxygen that the hydrophytes emit for breathing fish is in principle abundant, unless of course you are overpowered in an aquarium. To avoid problems with lack of oxygen at night, turn on the aerator and you will be happy, and when the light turns on the next day, after 30 minutes you can cut down.
On this optimistic note, I plan to finish dealing with the aeration of the aquarium, and I hope you have learned these important aspects. Thank you for taking a few minutes to read this article.
All the best to you, friends!
