The choice of aquarium water filter should be taken very carefully, as it is an important component of the successful maintenance of the aquarium and all its inhabitants.


Aquarium is a closed environment. All waste products of aquarium dwellers will accumulate in the aquarium if no measures are taken to clean it.

If the concentration of ammonium, nitrates and other toxic chemicals in the tank reaches a dangerous level, it can cause the fish to start to hurt and even die.

To solve this problem, you need a filter for the aquarium.

HOW DOES THE Fish Tank Filter WORK?

The filter in the aquarium performs a number of functions that help maintain the purity of the water and the health of aquarium fish.

The filter removes particulate matter and decomposing organic matter from the water. This and uneaten food, dust particles, settled in the water, rotting leaves of plants, etc.

The filter will also remove harmful chemicals that accumulate in the process of fish life – ammonium, nitrates and other toxins. If these toxins are not removed, they can quickly reach high concentrations in the water and quickly poison your fish.

Fish Tank Filter FUNCTIONS

There are three different aquarium filtration methods: biological, chemical, and mechanical.

At least a biological filtering is used in every aquarium. Aquariums are small ecosystems, and in order to maintain biological balance in them, a healthy colony of beneficial microbes must live, which help to filter water and keep it clean.

Subsequently, other filtering methods can be added to increase the filtration capacity or to cope with a heavier load than a simple biological method.

These additional methods are chemical and mechanical filtration.
Some professional filters use all three methods at the same time to ensure the best result – a safe and clean environment for your fish.

Biological filtration uses beneficial bacteria, processing waste produced by fish, plants, etc.

The substrate actually works as the most important element of a biological filtration system, since it provides a large surface area for the growth and prosperity of microorganisms.

It is important that a biological equilibrium is established in the aquarium before launching fish into it, since it takes 1-2 weeks for the colony of beneficial bacteria to develop on gravel or sand.

Since the substrate is so important for biological filtration, it is also important to clean it regularly when you change the water in the aquarium. Use a gravel vacuum cleaner to suck out pieces of uneaten food and fish waste products.

Never rinse the gravel in hot water, as in this case you will kill the entire population of beneficial bacteria that are directly involved in the process of establishing biological equilibrium.

Plants are also a very important part of the biofiltration system.

You can increase the efficiency of biological filtration by launching various crustaceans and snails into the aquarium, which also help in filtering water.


Chemical filtration functions using carbon or chemical resins, or other adsorbing materials to clean the dissolved particles in the aquarium.

Activated carbon is full of millions of tiny pores or holes that act as small “pockets” for the whole suspension in water. These pockets collect all the dirt from the water until they become clogged, after which carbon is simply converted into a biological filter.

Chemical filtration can remove other chemicals, such as copper and chlorine, as well as dissolved proteins and carbohydrates that are found in feed and fish waste. Also, carbon can absorb any medication that you have diluted in water.

Pay special attention to antibiotics. If you are treating fish in an aquarium, first remove the filter element with carbon and do not install it until the treatment period is over.


Mechanical filtration works by filtering water in an aquarium through a spongy medium that physically traps debris and solid particles that float freely in the water column. It can be a porous sponge, a sintepon or some other kind of material that is placed inside the filter to trap dirt as it passes through it.

You need to make sure that the mechanical filter works with maximum efficiency – these are two key elements: the flow rate and the filter material.

Mechanical filters usually come with pre-set water flow rates, but you can also change them manually. For example, you can reduce the flow rate if you keep fish like betta.

Filtering elements for such water filters are currently widely represented in the trade and have various shapes, sizes and densities.

Too small pores in the filter element will quickly become clogged and it will be necessary to wash it often, and the filter element with large pores, on the contrary, will have to be washed less often, but the filtration quality will be worse. You need to find the golden mean by selecting the quality of the filter element.

When choosing the right Fish Tank Filter for an aquarium, you need to consider many different variables. These include aquarium size, filtration technology, regardless of whether you use cold or tropical water, fresh or salt water, aquarium lighting, and more. Here are the basic requirements on the basis of which you need to select the Fish Tank Filter:

    All Fish Tank Filters are supplied in trade with the volume of the aquarium indicated on the box for which they are suitable. Do not neglect this data.
    What filtration technology is suitable for your tank? Would it be enough to use a small internal filter or do you need a canister type filter? Some types of filters require more frequent preventive measures, which may not always be a good choice, considering if you are often away from home and you do not have time to systematically maintain it.
    You need to choose a filter that will remove all ammonia and other toxins released by the fish into the water. If you choose a filter that is too small for a fish population in an aquarium, you may experience a higher level of toxins than is safe for aquarium inhabitants.
    Do your fish enjoy rough water or prefer a more current of water? Many fish do not like a strong flow of water and difficult to adapt to filters that create a strong current. Consider the requirements of your fish and select a filter that does not cause them discomfort.
    The cover for the aquarium also imposes certain requirements for the construction of the Fish Tank Filter.
