Canister fish tank filters are aquarium filters that are large and powerful and is used for biological, mechanical and even chemical filtration. Canister filters are external filters that are usually placed below the tank.

Canister fish tank filters are hardy and require very little maintenance. Some are even able to go for a few months without having to have any maintenance performed on them.

These filters do vary depending on the brand and model. But in general, canister fish tank filters perform their filtration following the same principles. A magnetic impeller motor located in the lid of the canister drives water into the tank through large foam pads which traps large particles. The water will then flow through a series of chambers which contain different filter media which will cleanse the water to greater degrees of purification each time. The final process is when the water is passed through a media that is designed to provide biological filtration by providing a horbour for bacterial colonies. The final product is a thoroughly purified water that is pumped back into the tank from the top. The water can be supplied back through various options, either through a spill trough or a spray bar.
