The variety of internal filters in our stores has recently been pleasantly pleasing. Along with this, aquarium fish lovers have a question, which filter is better? The choice of filter depends both on the size of the aquarium, and on the number and sensitivity of the fish that live in it. Quite often, internal filters are used to purify water in aquariums. They are simple and universal.
Main functions:
- mechanical filtration;
- biological filtration;
- creation of water circulation;
- aeration.
The design of the internal filter for the aquarium is quite simple. The filter itself is small, consists of a pump with a foam sponge and a pump. If the sponge is very clogged and can not be cleaned, it can be replaced. The pump is an electric motor in which the fixed winding is hidden in a sealed housing, which prevents water from entering the pump.
In general, all internal filters for the aquarium are arranged according to a single principle: at the top of the device is a pump that pumps water through the filter material, cleaning it from dirt and saturating it with oxygen.
Selecting an internal filter for the aquarium
Before you buy a filter, you need to pay attention to the power of its compressor and filter material. The larger the volume of the aquarium, the more powerful the compressor should be, usually up to 1200 liters per hour. Most often, as a filtrate, a foam sponge is used, in some filters there is a compartment in which it is possible to put special fillers in the form of sand, stone, etc. The volume of the filtering material is up to 700 sq. Cm.
The most important criterion for choosing an internal filter is the volume of the aquarium itself, it should not exceed 180 liters, the limit - 200 liters. Also, when choosing an internal filter for an aquarium, you need to remember that if this type of filter can provide water purification in an aquarium with a large volume of water, its dimensions will be too large. In this case, you should choose a filter of a different type.
Installing an internal filter in the aquarium
This is not such a time-consuming process. It is enough to fix the filter on the side or back wall of the aquarium with the help of suction cups, in an unobtrusive and convenient place. If your "pond" is not covered with a lid, then special fastenings are provided for this, with their help an internal filter is fixed on the upper cut of the aquarium glass. filter in the aquarium horizontally to the bottom, directing the jet upward.
In order not to waste money, some fans prefer to install self-made internal filters in the aquarium.

- There are gaps between the elements, and water seeps into the filter;
- often unaesthetic.
Therefore, it is better to get a good filter and do not waste precious time assembling a very inconvenient device.
