There are two types of
aquarium filter: internal and external. Internal aquarium filters are affixed to the back or side of the aquarium,
and is ideal for the smaller fish tank. They are inexpensive and very simple both to install and
maintain. Aquarium water is drawn into the filter, and passed through the filter
Media may be sponge, ceramic noodles or
carbon, and is often interchangeable. Dirt and debris is trapped in the media and purified water is pumped
back into the fish tank. Whilst regular maintenance and cleansing of the aquarium filter media is essential,
it is important to note that filter media should not all be replaced in one go. Beneficial bacteria build up
on these 'beds' and it is imperative that some of these are kept back to deal with the nitrogen
The external aquarium filter is ideal for the
mid to large sized aquarium. The advantage of external aquarium filters is that they are kept outside of the
tropical fish tank. They therefore do not take up precious aquarium space and are much more discreet, quietly
tucked away in the aquarium cabinet.
As external filters are not on show this means
they can be bigger, which really does equal better! They are easy to install and require less maintenance
than the internal filter. Typically, we would expect to clean media in the external filter once a month, as
opposed to once a fortnight with the internal filter.
