Types Of Fish Tank Filters

Assuming that beginner aquarists often have problems choosing the right filter for an aquarium, we present the most popular filters for small and large aquariums.

Internal filters are the simplest. They should be placed inside the aquarium and attached to the glass with suction cups or special hooks. Water is sucked in the lower part of the filter, passes through the filtering element, which is used as foam rubber or synthetic wool, and then released in the upper part of the filter. The outgoing jet is directed to the surface of the water in the aquarium and thus effectively enriches the water with oxygen. This type of filter is recommended for all aquariums. To the best of its advancement, this filter may, in addition to mechanical filtration of water, contain a biological filter.

Advantages of internal filters:
– low price;
– low power consumption;
– well filters water.

Disadvantages of internal filters:
– small filter element;
– low performance as a biological filter;
– takes place in the aquarium.

In the middle of the water is supplied from the aquarium through the intake manifold with filter. Then the water is drained back to the aquarium through the pan. This type of filter is recommended for all aquariums. It is especially recommended for aquariums of large volumes in which the movement of water is not desirable.
