What is the importance of an Aquarium Filter?

An aquarium filter keeps the environment inside the aquaria healthy by constantly removing the unwanted substances inside. The water inside the aquaria contains a number of substances such as excess food, decaying matter, and the fishes continuously keep excreting waste materials as they swim around.

It’s vital that these toxins are properly cleaned to prevent the fishes from dying. These chemicals gradually create a poisonous stage known as “ammonia stress” that leads to poisoning the fishes with ammonia, eventually killing them. An aquarium filter eliminates these risks by keeping the environment healthy for the fishes.

How does the Aquarium Filter Work?

The process of filtration takes place in three ways: biological, chemical, and mechanical.

Biological Filtration

Biological filtration is an absolute must if you want to reduce the amount of maintenance required for the aquarium. As we mentioned earlier that the fishes constantly excrete as they roam inside the aquaria. Just like human waste or any other animal waste, these can create a toxic environment if not cleaned properly.

A biological filtration converts the poisonous ammonia into Nitrite and then convert the Nitrite to Nitrate. Nitrate is indeed quite harmless compared to ammonia or Nitrite. However, if the water isn’t changed regularly then this “innocent” (pun intended) chemical can cause kidney, liver or eye damages to the fish.

Chemical Filtration

The chemical filtration is basically the removal of toxins and other impurities from the water. The process is obtained by providing carbon or chemical resins which extract the toxins from water.

The activated carbon will keep absorbing the toxins until it becomes saturated. The activated carbon of 1 cubic inch can filtrate up to 2 gallons of water for about a month, so, little will definitely go a long way with chemical filtration. However, to make this process work, there are several criteria that should be met.

The chemical content of the water plays a crucial role in it. Water with high chemical content will saturate the activated carbon faster. If you put additional supplements or elements in the water that will also speed up the saturation process.

An even rate of water flow is also very important for this process. If the water moves too quickly then the carbon will not be exposed to the toxins. Therefore, the result will not be as effective as expected.

If there’s an excess population of fishes or insufficient amount of water changes, then that will also make the carbon to get saturated at a higher rate.

Mechanical Filtration

The mechanical filtration process is also known as particulate or physical filtration. The purpose of this filtration process is to maintain water clarity.

In this process, a strainer catches the floating elements that can’t pass through the openings of the filter media. The media could be aquarium gravel, sand, filter pads or even a filter floss.

The result of the mechanical filtration process relies heavily on the quality of the media. The finer the media, the better it will strain.  Mechanical filters generally have multiple layers of media to get the optimum result out of it.

The market is filled with countless models of filters. Sometimes it gets really hard to choose the right one for yourself. In this review, we have picked the best 10-gallon fish tank filters, keeping in mind a wide array of users with different needs and budget range.
