It is almost impossible to keep an aquarium without a pump. This small device is an essential element in creating water flow. The aquarium pump, being a pump, helps decorate the reservoir, creating all kinds of currents, and purify the water by pumping it into the filters . To maintain the balance of the water world, it is necessary to choose a product whose power would exactly correspond to the volume of the reservoir. Since in the working condition any pump heats water, this property can not be ignored by choosing a model for a marine aquarium .
Another important detail that you should pay attention to is the shaft. Most often it is made of ceramics or stainless steel.
Types of Aquarium Pump
Submersible aquarium pump. For the production of most models, shockproof plastic is used. Devices differ in size, height of water, power and performance. The pumps begin to work only after they have been immersed in water. Some models are able to regulate the supply of oxygen. They are attached to the glass by suction cups or by means of a magnetic device. Products of small size aquarists try to hide among the scenery.
External aquarium pump. The external model is installed outside the reservoir. It pumps water, which is fed to the inlet through a pipeline. From the submerged differs only in the way of installation, although many consider it a better and more versatile invention. Some manufacturers include a synthetic large-mesh sponge that performs the filter operation, which prevents large particles from entering the rotor.
Almost all aquarium water pumps are noiseless. The latest developments are electronically controlled, many of them are presented in the market as universal. They have a good thermal protection, which protects the device from overheating. The new generation of models is designed to work in liquid and air environment, perfectly suited for creating any type of fountains. To extend the life of the product, it is recommended not to allow it to work without water. The liquid level during installation should be higher than the pump itself. This method allows water to flow freely to the device.
