Canister filters are typically placed on the outside of your tank, usually with one piece inside the aquarium, intake, and outlet. Canister filters have inlet and outlet fittings which allow for the water to flow in and out of the filter. Generally, you can adjust these tubes so that they fit your fish tank perfectly.
Canister filters have a motor which propels the water into the canister to be filtered. Some models have mounted motors that use gravity as well as the motor to start the filtration process. Once the canister filter is filled with water, the internal pump forces the water out of the filter and back into the fish tank.
