Pump for aquarium: purpose and types
In order for the aquatic environment of the aquarium to be as close as possible to the natural conditions, 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.
Filtration should be carried out in almost every artificial reservoir (except the Dutch one). For this purpose, and designed water pump for the aquarium. After all, any aquarium is, above all, a closed biosystem. As a rule, in the natural environment, the concentration of living organisms and plants is much less than in a domestic artificial pond. Therefore, the water in it is more and much faster polluted by waste products of its inhabitants, the remnants of food, etc. This can lead to a high concentration of harmful substances and poor health or even illness and death of the fish.
Pump in the aquarium performs the function of pumping water. Differently they are called water pumps. In fact, the aquarium pump is the simplest filtering device. Most often, they operate on the principle of centrifuges and are driven by magnets embedded in the engine and impeller. With the help of a pump, you can either pour water into the aquarium, or feed it to devices located on its outer side (mounted filter, sterilizer, etc.).
In fact, pumps for an aquarium produce a water flow in it that facilitates the movement of water layers, which, in turn, leads to their saturation with oxygen. The water does not stagnate, it is less susceptible to blooming, and the fish feel much better with a normal degree of oxygen concentration.
In addition, the pump for the aquarium 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 a compressor for supplying air. Sometimes they are additionally equipped with a water heater, an UV lamp, etc. Such a design, in fact, is already a complete filtering system. The pump for the aquarium is usually equipped with powerful suction cups that allow you to securely fix the device on the glass. Sometimes for fixing use special clamps.
By design also distinguish between deep and external pump. Submersible (deep) are located right in the aquarium. External (external) beyond.
Before you get a pump for an aquarium, you need to ask the seller what material its body is made of. This is of great importance, since such an important parameter as the degree of noise of the device depends on it. Water pumps of varying capacity are available for aquariums of various sizes.
When purchasing a pump for your homemade artificial reservoir, in addition to financial capabilities, be guided by such factors as its power, functionality and noise.
