Every experienced aquarist knows how important it is to have a high-quality aquarium pump suitable for the size of the tank. It enriches the water column with oxygen, does not allow water masses to stagnate, thus avoiding clouding and the development of various diseases and putrefactive processes that may adversely affect the inhabitants of the aquarium.
Types of aquarium filter water pumps
The principle of operation of air aquarium vodushnyh pumps is quite simple. With the help of a special device, a mechanical injection of air takes place in the outlet opening to which a special hose is attached. This hose falls as low as possible into the aquarium and water is saturated with oxygen. Most often, a special sprayer is attached to the end of the Schlag, which breaks up the air stream into many tiny bubbles, which allows the aeration process to be carried out much faster. Aeration is called the supply of air to the water mass, so aquarium inlet pumps are often also called aerators.
Depending on the mechanism of air injection, there are two main types of aquarium water pumps: diaphragm and piston. In membrane oxygen supply to the air occurs due to the movement of special membranes. This is a great option for a silent aquarium water pump, so it can be turned on all the time, even at night. Such an air pump will not interfere with the rest of the people in the room. But there are similar devices and their disadvantages. So, such a quiet aquarium inlet pump does not have enough power to conduct aeration of very large water tanks or aquarium columns. However, for home aquariums it is usually quite enough (the largest volume of water in which a membrane water pump can work is 150 liters).
The second type of aquarium vodushnogo pump works on the basis of the movement of the piston, which forcefully pushes the water jet into the hose. With this mechanism, it is possible to create even very powerful aquarium inlet pumps capable of coping with large volumes of water. Most often they are used in aquariums located in public places and having a large size. Aquarium columns are also most often supplied with a similar vodshny pump. The disadvantage of this mechanism is an increased noise level compared to the membrane variant.
Installation and use of a water pump
Most often, the air / water pump should be located above the water level. Therefore, its external unit can be put on the shelf next to the aquarium or directly on its cover. There are also options with vacuum suckers, which are easily fixed to the walls of the aquarium from the inside or outside. Depending on the design features, the aerator can operate from an electrical outlet, or from batteries. After installation, the pump tube is lowered as low as possible into the aquarium, it is advisable to place it on the bottom (some owners, guided by aesthetic considerations, bury sprayers in the ground, although this is not recommended).
If we talk about the mode of operation of the aerator, then in the case of silent mechanisms, most aquarium owners leave them to work all the time, since this device does not consume much energy. Meanwhile, some owners believe that it is more useful to periodically turn on the aquarium inlet pump (the optimal mode is two hours of work and two hours of rest). In addition, it is recommended to constantly turn on the aerator after feeding the fish, as well as at night. In this case, the aquarium will be best enriched with oxygen, and the putrefactive processes caused by the products of the vital activity of fish and food debris will slow down.
