What Is A Canister Filter?

Canister filters are basically used for cleaning aquariums.
It is a filter that removes water from a fish tank via a sieve, intake tube, or valve and then passes the water through the filter media. The water is then pumped back to the aquarium using a spray bar.
These filters are really efficient and last long if they are operated in the right way. You can even select the type of filtration according to your tank.
This can be done by customizing the filter media. You don’t really have to invest lots of energy in its maintenance. It’s because the water flows through the filter media rather than flowing over the media.
One important thing that you should remember is to replace the carbon in the filter really quickly. The carbon would begin to release toxins otherwise.
If you have a tank in size medium to large, a canister filter is a right option for you. You can filter a huge volume of water using a canister filter, that too, in a really short time.
How Does It Work?
Before getting a canister filter, you should have an idea of how this thing works. This way, you will understand whether the product is convenient for you or not.
With that said, a canister consists of three essential parts. These are motor, cartridge, and tubing.
However, the central part is a cylindrical device. This cylinder contains a pump and a filter medium.
Basically, the process used in this device is Siphoning. In this process, the water flows in two water bodies, and there is no interruption between those two bodies.
A canister filter draws water out of the aquarium into the canister. The water is then passed through several filter media, where it is cleaned step by step.
Different types of canister filter have different directions of flow of water. The water may move from top-to-bottom, bottom-to-top, outside-in, or center-out.
After flowing through the filter media in a sealed canister, the water is pumped back to the aquarium. Canisters usually come with water pumps, but you need an external pump to pump the water in rare cases.
How a filter works depends upon your choice. Canister filters can provide filtration using chemical, mechanical, and even biological filtration media.
You have the option to select the process according to your needs.
