The need for a filter element

Filters are responsible for the mechanical, biological and chemical cleaning of the aquarium. Some systems also saturate water with oxygen, but experts recommend buying separate aerators.

Internal filter

The internal filter is the simplest design, suitable for small primitive aquariums. Principle of operation: water enters the lower section of the apparatus and exits through the upper one, while simultaneously being saturated with oxygen. Such a device is an attractively affordable price, simple installation and low power consumption.

Among the disadvantages of the internal filter, we note that it takes up space inside the aquarium. Filtering and aeration is carried out by such a system sufficiently only in small tanks.

Another non-obvious minus is associated with the need to frequently remove the filter. In order to remove it, you will have to put your hands in the water. This can lead to infection in the water and infection of its inhabitants.

  5. Before connecting the device, it is necessary to fill it with aquarium water using self-flowing. If this is not done, the air in the tubes will interfere with the normal operation of the filter. Procedure: first open the tap to fill the water intake tube. Wait for the filter to fill. Then close the inlet hose and open the valve for the exhaust pipe.
  6. Now you can connect the external filter to the network and open both taps.
  7. Read the instructions carefully, since different manufacturers may have nuances associated with both the use and installation of the device.

If the external filter has strong power, you need to put a net on the end of the tube so that the system does not suck in small fish.

If the water does not flow well into the external filter, then you need to clean the air plugs in the pipes. Just turn the device on and off several times. If it does not help, drain all the water and refill the device.

Choose a filtering system in accordance with the needs of the aquarium and do not be afraid of modern designs: instructions will always help you with installation. Also do not forget to regularly clean the filters from the remnants of dirt and organic matter. The purity of the water and the comfort of the fish in it are worth these small efforts.
