Filter For Aquarium Which Is Better

A prerequisite for the health of your pets and the beautiful appearance of the aquarium is its constant cleaning. For this purpose, an Fish Tank Filter is applied, which is selected depending on different conditions and can be internal, bottom, external, with additional filtration, ionization and aeration of water. Modern manufacturers of filtering devices create designs that can solve many problems by altering the contents of the filtration chamber. Often the choice depends on the type of fish or reptiles and their number.

What is an Fish Tank Filter?

The standard design of the filtering device includes a pump-pump, a filtration chamber, a spongy removable nozzle for collecting waste products of aquarium inhabitants. Water is taken and passed through a sponge in the water, and the remaining filter elements can be located both in the water and outside. Their efficiency or throughput depends on the performance of the pump, which pumps water into a special compartment with filter media.

Why do you need

A filtering device is necessary to collect and remove waste products from aquarium inhabitants. Additional features include the removal of excess mineral salts and the addition of ingredients that favor the growth and reproduction of the inhabitants of the aquarium. Passing through the filtering module, water can be ionized, saturated with oxygen or carbon dioxide, excess microorganisms can settle on a special filler in the filtration chamber.

How does it work

The principle of the filter is simple – the pump-pump draws water into the filtration tank. When passing through the outer sponge, fish feces and large debris linger in its pores. On the material with which the filtration chamber is filled, the deposition of unwanted microorganisms or the addition of salts and minerals occurs. Water when it passes through radiation is ionized, the compressor is saturated with oxygen or carbon dioxide and returns back. This filter works constantly, so the water in the aquarium has a clean appearance, and its inhabitants are healthy and active.

By location, the filters are divided into:

  • external – the body is installed outside the aquarium, the inflow and outflow is made through the nozzles;
  • internal – fully or partially placed in water;
  • cascading – hung on the glass of the aquarium;
  • bottom – the filter element is located under the aquarium soil.

Fish Tank Filters vary in filtering mode:

  • mechanical – cleaning is done by running polluted water through a filter sponge;
  • biochemical – cleaning is performed by neutralizing harmful substances and impurities under the action of beneficial bacteria;
  • combined – combine sequentially mechanical and biochemical purification.

Aquariums come in fresh and salt water. Each of these types requires its own kinds of filter elements. The choice of its type or filtering variant depends on the size of the aquarium, the species of fish and its other inhabitants. Every experienced aquarist knows for which fish and aquarium plants, what kind of filtration is needed. A novice fish lover should choose a universal combined filter and consider all possible options. Airlift filter module with zeolite is useful for removing ammonia from the aquarium.

How to choose

The initial information for choosing a filtering device is the volume of water and the required capacity. For a small rectangular or round aquarium and large fish fit mechanical internal filter. For a large size and number of aquarium fish – a combined device with tanks for biofiltration fillers is required. It will not be superfluous to install a bottom filtration element (false-bottom) – this will make clean not only the water in your tank, but also the bottom soil coating.
