External filters are installed in aquariums in excess of 300 liters. The device is placed near the tank, two hoses are immersed in water. One of them serves for pumping dirty water, the second fills the aquarium with clean water after a preliminary cleaning system. This type of filter is efficient and economical. However, the cost is quite high and the equipment takes up a lot of space.

Bottom filters

Their second name is false. The filter plate is laid on the bottom of the aquarium. Top closes ground. Since the filtration is carried out from below, the water is purified in two ways: through the filter and through the soil. These devices are not suitable for large aquariums because of their poor performance. It is also noted that they are difficult to operate.

Mounted filters

This device is popular with aquarists. The device is installed near the wall of the aquarium, and the filter device itself (filtering mechanism) is lowered into the tank. The performance of this type of equipment is different. But for small aquariums, they are not suitable.

What are the internal filters?

Filtration systems are divided into three types:

  1. Mechanical.
  2. Biological.
  3. Chemical.

Next, we consider them in more detail.

Mechanical cleaning

Water purification is carried out using a sponge located in the filter cup. Water is taken from the bottom through special holes in the glass. Particles of debris and dirt settle on the sponge, and the water from the filter comes out already cleared.

Filters with this cleaning method are suitable for various aquariums.

Chemical cleaning

The basis of the internal filters for an aquarium with a chemical cleaning method is coal. Water passing through the carbon filler in the filter, leaves an unpleasant smell, pollution, and most importantly, ammonia. It is filled with useful impurities and minerals and in this form goes into the tank.

Aquarist Reviews

As always, opinions are divided. Other aquarists are satisfied with Tetra filters, agree that the devices work well enough, without complaints. And someone says that after the first disassembly and washing the filter began to work worse, buzzing. And even it flows.

Reviews of the internal filter for the aquarium of both brands are different. Choose a device for the aquarium should be carefully examining the technical characteristics.

Conclusion

Which internal Fish Tank Filter is the best? There is no objective answer to this question. How many people, so many opinions. One likes the Polish company Aquael, others prefer the German brand Tetra.

What to consider when choosing a filter? First of all, technical specifications. It is necessary to understand that in an aquarium with a volume of 50 liters a filter designed for servicing a 30-liter tank will be insufficient.

Secondly, the price category. A good filter cannot be cheap. The average price of devices with a minimum performance is 800 rubles. The more powerful the device, the more expensive it is.

And thirdly, you should think about the future inhabitants of the aquarium. For small fish do not need huge tanks with a powerful filter. The flow of water will destroy the fish. Conversely, small filters are not placed in large aquariums. Insufficient amount of oxygen will kill its inhabitants.
