What Is a Canister Filter?
The canister filter is very common
It is a water filter for aquariums that includes filtration media outside the aquarium. It typically has a pump, filter media, gravity, and lift tube.
This filter allows tank owners, aquarists, or fish keepers to use various filtration methods, including toxic chemicals and fish waste.
You can use a canister filter in many fish tank types, such as saltwater tanks, freshwater tanks, turtle tanks, and custom-made aquariums.
Many tank filters can be submerged in water during use, but that is not the case with the canister filter.
Canister filters are the opposite. To work correctly, you must keep it outside your aquarium and below the water level.
As long as they come with proper filtration media, canister filters can deliver water filtration of all kinds, including mechanical filtration, chemical filtration, and biological filtration.
How does A Canister Filter work?
The mechanism of a canister filter is simple
The canister filter has a simple structure, and so does its mechanism of action. Its operation process basically the following three steps:
Step 1: Draw the Water
It will start by drawing the water outside your aquarium utilizing one lift tub.
It then passes the water to a pressurized canister that includes various filtration media that clean the water inside the canister.
The direction of the water flow may vary depending on your chosen filter model and the brand. This direction might be from bottom to front, top to bottom, back to front, outside to inside, and more.
Step 2: The Filtration Process
After the water is drawn out of your aquarium and goes inside the canister, a pump will push it to the part of this canister where filtration occurs. The filtration process refers to the tank water going through various filtration media.
The filtration media would deliver different kinds of filtration, including chemical, mechanical, and biological filtration. It depends on the filter media you use with your canister filter.
Step 3: Return the Water to Your Aquarium
After the canister filters the tank water, the pump will push it back to your aquarium. Your canister filter utilizes one water pump to move the water as this filtration system is sealed.
