The Canister Filter
This type of filter is kept external to the fish tank as a separate unit. It is essentially a bucket shaped container full of media. Hoses uptake and return the water back to the aquarium.
Keeping the filter external is useful for saving space inside the tank. The unit is also easy to access for maintenance or inspection.
With such a large compartment for a range of media a canister filter has a good capacity for cleaning the water. They are often selected for larger aquariums where a large volume of water needs processing.
Just how much water a canister filter will process is typically listed on the product. It will often state how many liters of water it can process in an hour.
