Pump for aquarium: purpose and types
In order for the aquatic environment of the aquarium to be as close to natural conditions as possible, and its inhabitants feel well, it is necessary to use various additional equipment. Almost every aquarium requires aeration. In addition, additional water filtration is often necessary.
Filtering should be done in almost every artificial pond (except Dutch). For this purpose the water pump for the aquarium is designed. After all, any aquarium is, first of all, a closed biosystem. As a rule, in a natural environment the concentration of living organisms and plants is much less than in a home artificial pond. Therefore, the water in it is more and more quickly contaminated by the products of the life of its inhabitants, the remains of food, etc. This can lead to a large concentration of harmful substances and poor health or even disease and the death of fish.
The pump in the aquarium performs the function of pumping water. Otherwise they are called water pumps. In fact, the pump for the aquarium is the simplest filtering device. Most often they operate on the principle of a centrifuge and are driven by magnets built into the motor and impeller. With the help of the pump, you can both pour water into the aquarium, and feed it to devices located on its exterior (hinged filter, sterilizer, etc.).
In fact, the pumps for the aquarium produce a water stream in it that promotes the movement of water layers, which in turn leads to saturation of their oxygen. Water does not stagnate, is less prone to blooming, and fish with a normal degree of oxygen concentration in it feel much better.
In addition, an aquarium pump can be used to create various aquarium effects, for example, fountains and waterfalls. Therefore, it can also be called equipment for decorating an artificial reservoir.
Previously, such devices were sold without additional accessories. Modern pumps can be equipped, for example, with an air compressor. Sometimes they are additionally equipped with a water heater, ultraviolet lamp, etc. Such a design, in fact, is already a full-fledged filtering system. The pump for the aquarium is usually equipped with powerful suction cups, which can securely fix the device on the glass. Sometimes special fixatives are used for fastening.
The design also distinguishes between deep and external pumps. Submersible (deep) are located right in the aquarium. External (outside) outside of it.
Before you buy a pump for the aquarium, you need to ask the seller what material is made of her body. This is of great importance, since this depends on an important parameter, such as the degree of noise of the device. Various water pumps are produced for different sizes of aquariums.
Buying a pump for your home artificial pond, in addition to financial opportunities, be guided by such factors as its power, functionality and noise.
