Good day, dear colleagues. glad to welcome you again on my blog. Today I want to talk about the importance of oxygen in the aquarium.
Last time I talked about such a miracle as a nano-aquarium, and today the topic will be more specific. Every aquarist should understand and know the things that occur in an aquarium with a lack and an excess of oxygen, as well as its effect on animals.
But let’s understand in order.
As you know, an aquarium is a closed ecosystem. For its inhabitants, in particular for aquarium fish, oxygen is vital, which is then converted into carbon dioxide. In the process of photosynthesis in the daytime, plants consume carbon dioxide and produce oxygen.
With the right proportion of aquarium fish and aquarium plants, everyone will feel good. The problem may be this: the balance between the representatives of flora and fauna may not correspond.
With insufficient oxygen supply, all the fish that live in the aquarium may suffer from oxygen starvation, so you need an aerator.
Oxygen in aquarium water is vital for almost all aquatic organisms. A lot of species of aquarium fish are demanding on the chemical composition of water, or rather on its main indicator – the level of oxygen.
Oxygen dissolved in aquarium water plays a key role in the vital activity of hydrophytes and hydrobionts. The amount of oxygen consumed depends on their physiological characteristics: some can easily live in oxygen-poor water, and some feel the slightest difference in the level of oxygen.
The oxygen deficiency in invertebrates and aquarium fish is very detrimental. Reduced oxygen levels will greatly affect the physical development of the fish.
According to their appetite, it will not hit in any way, but the method and quality of digestion in fish will change. With food, fish will absorb less nutrients, which in turn will greatly affect their growth.
Do not forget that oxygen is actively consumed during breathing various crustaceans and mollusks, aquarium fish and bacteria. The more aquarium fish in an aquarium, the more oxygen they need.
With its lack of water, the amount of carbon dioxide will become larger, which can result in freezing, i.e. to suffocate.
A zamor can cause an overcrowded aquarium, algae blooms, the use of medications and an increased temperature of aquarium water. To avoid all these negative aspects, control the active reaction of water and do not allow its sharp jumps, plus provide mixing in the upper layers of water.
In addition to everything else, try to prevent disruption of biological equilibrium.
The temperature of the water affects the fish very badly, which leads to an acceleration of metabolism and deterioration of gas exchange. As a result, the amount of carbon dioxide in the blood of fish increases, which leads to oxygen starvation, and in the future this will lead to the death of fish.
Especially dangerous is the lack of oxygen in fairly dirty water bodies in which carbon dioxide will oxidize dead organic matter.
Try in your banks to control the number of fish, and in particular the live beetles (swordtails, molines, guppies and placiums). If there is no overpopulation, then problems arise and should not be with oxygen starvation and an excess of organic matter.
Pay special attention to the filtration and aeration of water in the summer, when the inflow begins. However, fish are not the only consumers of oxygen.
The level of oxygen in the water is not affected by the food eaten, dissolved organics, can illumination, the number of plants and so on. If you thought that oxygen in an aquarium is necessary only for breathing its inhabitants, then you are mistaken. Oxygen is also used in the oxidation of organic and inorganic compounds.
When the number of fish in the aquarium increases, the ammonia content in the water will also increase, which will also oxidize.
The main oxygen supplier in an aquarium is aquatic plants, which during photosynthesis release oxygen into the water. Of all the varieties of aquarium plants, marsh representatives of hydrophytes emit very little oxygen.
Those plants that grow quickly in aquariums, they release much more oxygen into the water than representatives of the bog environment.
At this article is over, I think the post turned out useful and interesting. I wish you all the best!
