The work is devoted to the selection of a water pump for the aquarium. The article discusses the nuances that you need to pay attention to, selecting the desired model.
One of the devices that should be in the arsenal of any aquarist is considered water pump. So called a device that provides forced air into the aquarium.
What is a water pump for?
In natural water bodies, sufficient oxygen content in water is provided by “green plantings” and the photosynthesis process occurring in them. Also, part of the oxygen is provided by a large contact area of water with atmospheric air. In the conditions of artificial reservoirs it is rather difficult to reproduce these processes to the full. therefore

resort to forced saturation with the help of water pumps.
However, from each rule there are exceptions. This axiom is not passed and the statement that the air pump for the aquarium is required. Some species of fish breathe atmospheric air, rather than dissolved in water. And if you plan to populate a homemade artificial reservoir, for example, with pearl gouras, macropods, speckled catfish or Coridoras catfish, then this accessory is not necessary for them. Although a veil of small bubbles in the background will add additional attractiveness to the aquarium.
Also, the water pump is optional for aquariums whose population is sparse or the presence of fish is not planned in principle.
Another function of the aquarium vodoshnogo pump – ensuring the circulation of water. With it, temperature uniformity throughout the water column is achieved.
The basic rule of choice.
Choosing an air pump for an aquarium, you need, first of all, to focus on its performance. The desired value of this indicator is directly dependent on the volume of water that needs to be saturated with oxygen. It’s easy to calculate sufficient performance. It is enough to multiply the displacement of the aquarium by 0.8. This is the performance per hour per liter

the volume will be sufficient to provide the desired degree of aeration. Although, as experts note, in some cases this figure can be reduced to 0.5 l / h, and in some cases it is better to increase to 1 l / h. It all depends on what kind of inhabitants will inhabit the aquarium. After all, each type of fish feels more comfortable in conditions as close as possible to the natural.
According to the principle of operation, the air pump for the aquarium can be diaphragm or piston. The first kind has less power. But at the same time such water pumps are cheaper. However, for amateur aquariums with a capacity of up to 200 liters the capacity of a membrane water pump will be quite enough. At the same time, the price of such water pumps is significantly lower. Therefore, it is not necessary to arrange an unnecessary “arms race” for anyone, spending extra money on it. True membrane, often referred to as vibration, water pumps can be sources of significant noise. In piston models, this disadvantage is somewhat less pronounced. In addition, there are centrifugal pump pumps that can saturate water with oxygen from the air using a special nozzle. [sam_ad id = "15 ″ codes =" true "]
When choosing a water pump, pay attention to the presence of an air supply adjustment. This can be accomplished by installing a flow shut-off valve on the duct. But it is better to opt for a model in which the flow is regulated by a smooth change in performance.
Another argument in favor of a particular model of a water pump can be the noise level during its operation. But this can only be estimated empirically, including the unit before its purchase.
Summarizing, we can say that air pump for aquarium is optional, but in most cases a desirable technical tool. And his choice depends, first of all, on the capacity of the home pond.
