When we begin to prepare the aquarium so that our little pets can live in good conditions, we need to know the amount of oxygen that the water must have so that they can have good health. One of the main causes why fish get sick is due to the lack or excess of dissolved oxygen in the water. Therefore, it is essential to know the oxygen needs that the aquarium needs so that the fish can live in good conditions.
In this article we are going to tell you what the problem of lack of oxygen is and how to not have neither lack nor excess of oxygen in the aquarium.
Oxygen problems in aquariums
One of the main causes that can cause fish to get sick can be in oxygen. Mostly this occurs because the aquarium is not well regulated and lacks that balance that fish need to have a problem-free and disease-free habitat.
One of the main causes that can occur for fish to lack oxygen can be poor regulation of artificial air, mostly injected by pumps or bubbles. If so the water would be more than polluted with oxygen-limiting impurities.
All this derived from the fact that the aquarium can be overloaded with many fish for a small enclosure, this, apart from limiting the freedom of movement, prevents proper oxygenation.
To find out if the fish have a lack of oxygen, we will notice how they keep swimming on the surface for a long time, and according to which species they can try to jump out of the aquarium to take oxygen.
On the other hand, excess oxygen is not beneficial for the life of the fish either, an excess of it produces serious disorders such as the disease known as 'air embolism'.
Why does an oxygen saturation occur? If in the aquarium we have a habitat with plants that do their job well, there would be no problems to regulate it. But if the aquarium is subjected to a lot of sunlight, we alter the temperature of the aquarium and the plants will increase the oxygen by themselves, completely altering the life of the fish. Precisely the heater is the one indicated to regulate its temperature hence we avoid exposing them to sunlight.
We will notice that the fish have excess oxygen if we see that small bubbles are produced in their fins, then the fish should be transferred to a fish tank with the oxygenated water in its proportion, if on the contrary we do not realize it, the fish will die.
Neither lack nor excess of oxygen in the aquarium
We must know that a fish must breathe oxygen dissolved in the water in practically all cases. Therefore, it is essential that our water has enough oxygen for these organisms to live in it. It must be taken into account that the amount of dissolved oxygen will be modified depending on the number de peces and the size of the aquarium. If the aquarium is hot or temperate It is necessary to know that the solubility of the gases is inferior to the present one the aquariums of cold water. This makes tropical water fish have less oxygen than those that swim in cold waters.
An example of a fish that lives in cooler and more oxygenated water are trout. The volume of oxygen dissolved in air is less than that dissolved in the same volume of water. From this idea we can extract the importance of keeping the aquarium well oxygenated but not excessively.
As our aquariums are closed systems in which there is no movement of water, we are the ones who have to produce oxygen diffusion continuously. One of the ways is to install a aquarium oxygenator. The aquarium oxygenator is responsible for generating bubbles that are a way of breaking the surface of the water and being able to move it to trap oxygen from the air. Therefore, we must know that the amount of bubbles that rise will depend on the rate of dissolved oxygen in the water. Nap The amount of bubbles is small, the amount of dissolved oxygen in the water will be low. If you have a fairly high oxygen demand, you will have oxygen deficient conditions and the fish can suffocate.
To know this, we must know more or less the needs of each type of fish depending on the water and the amount of them. Oxygenator noise is a factor to consider. There are numerous types of aquarium oxygenator depending on its price and quality. The idea is to buy silent pumps since many others make a significant noise that can create discomfort in the fish.
Ways to oxygenate the aquarium
The filter itself to clean the water can serve to oxygenate the aquarium. If the filter is powerful enough to move the volume of water in your tank, you can point the water out at the surface. It is necessary to ensure that the water does not splash so that it does not begin to empty the aquarium and unnecessary noise is avoided. Placing the filter so that it oscillates on the surface is enough to oxygenate the aquarium. You can also take advantage of an internal filter that you have abandoned to be able to move the surface of the water well. This is how we achieve that the oxygenation capacity can increase.
Another way to oxygenate aquariums is by means of oxygenating plants. Plants help in the oxygenation of both ponds and aquariums. The downside is that it only supplies more oxygen during the day. They need an appropriate amount of light and carbon dioxide in order to photosynthesize. Plants breathe at night, this means that they will consume oxygen. This makes it unnecessary to use a device to oxygenate the aquarium and prevent the fish from suffering from a lack of oxygen.
In conclusion we can say that respiration is a vital process for life in fish and therefore it is important to oxygenate the aquarium correctly. I hope that with this information you can learn more about how to not have a lack or excess of oxygen in the aquarium.
Thank you very much indeed ...
Help me see why two more fish died: '(
I am oxygenating my aquarium with a backpack filter just, remove my oxygen pump and diffuser ... It has worked well for me ... Only a large scalar is on the surface for a long time, although this was also done before removing the pump and the diffuser…. Increase the flow rate of the knapsack filter so that the surface has more movement ... I will comment if with this the scalar «improves'
