How to choose an internal filter for a home aquarium

The presence of a filtration system in an aquarium is the key to maintaining the cleanliness and good health of its inhabitants. When choosing a filter, it is important to be guided by several important indicators at once, the most important of which is its type.

Modern internal filters are divided into four main types.

The first and most common is mechanical filters. They are a reservoir through which aquarium water is pumped under increased pressure.

Inside this tank is a filtering porous material like a sponge. Passing through it under pressure, water leaves mineral and organic particles in it. The main advantage of such a filtering system is its low cost, availability and small size, so that it does not take up much space even in a small aquarium.

But it also has serious disadvantages – in order for such filters to always work well, you need to frequently maintain them and replace contaminated filter media. In addition, mechanical filtration allows you to remove only large components from the water, but it does not cope with fine cleaning.

In order to filter out harmful substances and organic suspensions from water, a chemical filter is better suited. Its device is almost the same as that of the mechanical, with the only difference that water is pumped through the absorbent filler (most often in its role acted as activated carbon). Such a filtration system effectively absorbs toxins from the water, harmful gases (for example, ammonia and carbon monoxide), as well as other compounds.

Servicing such a device is required much less frequently.

The third type is biological filtration systems. Inside them, inside a special compartment, there are colonies of chemosynthetic bacteria capable of constantly splitting gases and organic waste accumulating in water. Such a filter is most effective as it does not require maintenance and guarantees constant cleaning.

But, on the other hand, it does not provide mechanical filtration and does not eliminate the presence of many toxic compounds.

To provide the maximum degree of filtration will help the fourth group of filters – combined. They consist of two or all three filtration elements. Due to this, such systems are capable of removing both mechanical suspensions and organic residues and harmful gases.

The simplest example of such a filter can be a mechanical one, in the compartment of which, besides the sponge, there is also coal.

What parameters to pay attention to? An important parameter that is responsible for the filtration rate is the filter power.

Small filters usually pump water slowly, which is enough for small aquariums, but for larger volumes, you should choose a device of greater power. Another important indicator is noise. Cheap filters during operation can make so loud noise that not only will they scare the water inhabitants, but they will not allow the owner of the aquarium to sleep well.

Therefore, it is better to choose modern branded models – they work completely silently. The most popular now are filters from manufacturers such as Tetra, Atman and Aquael.

They are convenient because almost all models of internal filters from these manufacturers have the ability to control the flow rate of water and do not require rinsing due to the use of a replaceable cassette system, as well as being highly reliable and noiseless. In addition, many filters have additional useful options, for example, tubes for aeration of water. That is why opt for the products of one of these companies will be the right solution for you and your aquarium.
