Hang On Aquarium Filters
Such hang on filters are easy to maintain because the whole unit is outside the aquarium. Filter media can be replaced without disrupting your fish. Hang on filters also save your aquarium space by not taking up any internal volume.
If there is one drawback to this type of filter it is the fact that it will not be suitable for aquariums with hoods. If your fish tank has a lid this may also cause some interference.
