When looking for a filter to use in a large aquarium, you want something that will be powerful and efficient enough to handle the increased volume of water. Canister filters are one of the best options available for larger tanks. These types of filters sit outside of your tank, connected by tubes or hoses. This allows them to pull water from the tank and process it through multiple stages of filtration before returning it back into the aquarium with improved quality. Canisters are great because they can contain multiple trays filled with different media such as activated carbon or ceramic rings which helps remove more particles from the water than other kinds of filters. They also usually include an adjustable flow rate which is beneficial for customizing your filtration system according to what type of aquatic life you have in your tank. In addition to being very effective, these types of filters tend to be quieter than other models since most noise comes from inside the tank itself rather than on top where these canister filters are placed
