What is a canister filter?

The canister filter is described as an external filtration system that helps to remove dirt, toxins and harmful debris as well as chemicals from your aquarium to provide aquatic species a clean and healthy living environment.

As an external filter, it provides more materials for filtration, which helps to increase its ability and effectiveness to rinse your water. Also, the canister filter operates based on 3 mechanisms: biological, mechanical and chemical filtration.

Biological filtration: the filtration is involved in breaking down nitrites and ammonia by nitrifying bacteria. The most important thing for the method is that you have to keep your water not too clogged so that the nitrifying bacteria may constantly expose to oxygenated water.

Mechanical filtration: the method involves trapping and removing waste participles. Unfortunately, the mechanical can’t get rid of all of the waste particles which are then suspended. The suspended particles contain harmful bacteria that may pose a detrimental threat to your animals in the aquarium.

Chemical filtration: Basically, you use some substance like carbon or zeolite to get rid of impurity in water with the mechanical filtration. However, it brings short-term benefits and works well for an emergency while it is not budget friendly.

How does a canister filter work?

Getting to know how the system work may be tricky and challenging to some extent, but it is essential if you want to equip your fish tank with the filter.

To be more specific, water runs into the canister through an intake pipe, and then after processed, the water is brought back to tanks through a return pipe. Also, it works best for planted and saltwater aquarium

Because the canister filter is a fully-flooded and sealed system, the intake and returns pipe, aquarium and filter interior create the constant movement of water. Regardless of the height of the latter placed on the canister; it doesn’t take the pump much effort to return water back to the tank.

An important to keep in mind is that the pump needs to be strong enough to force water through filter materials and get over the drag in the intake and then run to the return pipe.


The canister filter has gained popularity thanks to a number of advantages:

  • Because it is an external filter that is placed outside the fish tanks, your fish are left with for room for swimming and playing. Also, it allows you to  set up, clean the filter and do maintenance with easy because you could disconnect the machine for cleaning or maintenance without disturbing the animals inside the tank
  • Thanks to an awesome combination of biological, chemical and mechanical filtration, the filter is excellent in keeping your water clean and healthy.

  • Because the type of fish tank filter may come with a variety of types of media, you could have more media selection to suit your needs.
  • The canister is famous for the smoothest and quietest operation among all types of filters. Also, there is mostly no vibration while the filter is operating, so your fish is left with a peaceful place of living.
  • Though the canister filter provides an excellent combination of 3 methods of filtration, the mechanical filtration could be the strongest. This means it could remove nearly all debris and prevent it returning the tank.
  • Most of the canister filter is designed with an energy-saving system, and then you could save energy consumption in your house.

Despite great benefits, the fish tank filtration system also brings about unwanted effects such as the increased costs for accessories or the complexity of assembling and setting up.

What you need to consider before buying a canister filtration

The size of your fish tank

Measuring the size of your fish tank is of great importance to choose a suitable canister filter because the capacity of your machine needs to be compatible with the size of the tank to achieve the best cleaning result.

If you are up to your ears or somehow lazy, don’t buy a filter that requires frequent cleaning and maintenance because the job takes you a great deal of time and efforts.
