Canisters are my choice for tanks forty gallons or larger, especially for show tanks, as they can be completely concealed and not detract from the appearance of the aquarium. Because canister filters force the water through the filter media, they are particularly good at removing particulate matter. Some canister filters even have diatomic sleeves, or other add on features, to allow for special filtering situations. More About Filtration
