Aeration In The Aquarium And Everything You Need To Know About It

Fish breathe oxygen and exhale carbon dioxide, which plants consume during the day of photosynthesis, releasing oxygen. Plants play a major role in maintaining the required amount of oxygen. Different plants supply different amounts of oxygen. If the ratio of plants and fish in the aquarium is chosen correctly, then both gases are sufficient for them, and they feel great. If there are few plants and many fish, then the latter lack oxygen, in which case the aquarist resorts to aeration. In addition, aeration is needed in nursery aquariums, when large quantities of fish are contained in a relatively small volume.

Aeration In The Aquarium And Everything You Need To Know About It

Aeration performs the following tasks:

  • Saturates water with oxygen.
  • Creates a circulation of water in the aquarium.
  • It equalizes the temperature in the whole aquarium.
  • Destroys the bacterial and dust film formed on the surface of the water.
  • Simulates the necessary environmental conditions, such as flow. These conditions are necessary for some species of fish.

But if you have a lot of plants in the aquarium, you can not use aeration. aeration is used to remove excess carbon dioxide. Our industry produces various types of micro compressors powered by AC power. The drive in them is an electromagnet, which informs the lever connected to the rubber membrane, 50 reciprocating movements per second. They provide performance up to 100 liters per hour.

When you turn off the pump, water can rise through the hose and, if the pump is installed below the water level in the aquarium, then, according to the principle of communicating vessels, it enters the pump and spills onto the floor of the room. Vibro compressors need additional inventory – this is a hose and sprayer + suction cups, and clamps to adjust the air supply.

Foreign companies produce various air pumps with a capacity of 1 to 100 liters per minute. But do not choose too powerful compressor for your aquarium, because it can cause stress to the fish. What volume of aquarium is one or another compressor usually indicated on the package. For example, the FAT-mini filter aerator is designed for an aquarium of 30-60 liters, no less than no more. This filter aerator is the weakest of the FAT series, but its performance is from 50 to 250 l / h.

Many models are equipped with a built-in filter. Such compressors are very convenient. The air in these compressors is mixed with a water jet directed back to the aquarium, this creates additional ventilation. They are installed directly in the aquarium. Filtering materials from such filters are quickly contaminated and they need to rinse the filtering agent once a week.

Factors affecting the oxygen content in water

  • Temperature.
    Water temperature affects the oxygen content in water: the warmer the water, the less oxygen it contains, and vice versa. In addition, the increased temperature accelerates the metabolic processes in fish, with the result that their oxygen demand rises precisely at a time when its content in water decreases. This problem can be overcome by more intensive aeration.
  • Plants.
    Plants are often appreciated for their ability to produce oxygen. However, it should be remembered that at night they themselves consume oxygen and produce carbon dioxide. Thus, although plants can really help to meet the oxygen requirements of fish during the daytime, at night, all living things in an aquarium compete for oxygen, the content of which at this time of day is decreasing. Therefore, in aquariums, densely planted with plants, at night there may be a lack of oxygen.
  • Snails and other creatures.
    A large population of snails can have a significant effect on the oxygen content of an aquarium. Bacteria can do the same. Oxygen consumption by aerobic bacteria involved in the nitrogen cycle is permissible because, instead, they bring significant benefits. However, if an excess of organic waste is observed in an aquarium (for example, due to regular overfeeding of fish), the bacteria population will grow and absorb more oxygen than when rationally fed fish. Snails, of course, also increase the content of organic waste.

The value of aquarium water aeration, which is carried out with the help of special compressors blowing air from the nozzles through it, consists not only in the saturation of water with oxygen. Aeration, among other things, causes the mixing of water layers with air bubbles, helps to equalize the temperature in the aquarium at all levels, and especially if the water is artificially heated, eliminates sudden changes in water temperature, both horizontally and vertically.

In addition, the circulation of water created by a powerful stream of air simulates certain environmental conditions that are necessary for different types of aquarium fish. Aeration of aquarium water contributes to an increase in soil flowability, provides the necessary conditions for the normal functioning of soil bacteria, which prevents the accumulation and decay of organic residues and thereby the formation of gases such as ammonia, methane and hydrogen sulfide harmful to fish.

Tips and secrets of aquarium aeration

  1. Increasing the temperature of the water in an aquarium increases the oxygen consumption of its inhabitants and vice versa. Knowing this, you can quickly help the fish in case of asphyxiation.
  2. Hydrogen peroxide. Few people know about its use in an aquarium. She can:
  • revive choked fish;
  • fight against undesirable living creatures (hydras, planarians);
  • assist in the treatment of fish (bacterial infections, parasites, protozoa);
  • fight algae on plants and aquarium.

But you need to know how to use it correctly, otherwise you can only bring harm and poison all the fish. In this article we will not dwell on this. If someone is interested in this question, then the information can be found on the Internet.

  1. Oxidizers They are of different purposes: for long transportation of fish, for small and large aquariums, for ponds. The essence of the work: hydrogen peroxide and a catalyst are placed in a vessel. As a result of their reaction with each other, oxygen is released.

In conclusion, I will say that you should not underestimate the importance of aeration in an aquarium. Moreover, there is a large selection of equipment for it. You can find cheap and quality models.

When choosing a device, it is necessary to compare its capacity, the displacement of the aquarium, the number of inhabitants and their CO requirements.2. Typically, manufacturers indicate the recommended volume for each model.

And remember that only an aquarium with healthy conditions for the inhabitants can be beautiful.

A little about the excess oxygen in the aquarium

First of all, a surplus of2 no less harmful than a disadvantage. It can cause gas embolism in fish when air bubbles appear in their blood. As a result, the fish may die. Fortunately, such a phenomenon is rare. Nevertheless, you should not be zealous with aeration (for example, it is not necessary to install several compressors).

Changing water in small portions, controlling the composition of fish and the number of plants, regulating the flow of air from the compressor will help to achieve the perfect balance.
