Aquarium Filters & Media

Aquarium filters are basically available as two sorts – external filters and internal filters. Both of which carry their own advantages but where space allows, an external filter is always the better choice due to the high capacity of filter media and usually higher turnover of the fish tank water.

When choosing an aquarium filter you must always buy one which is rated for your size of aquarium. An easy calculation to use when trying to work out the volume of your aquarium is LxWxH in CM then divide this number by 1000 which will give you your fish tank volume in litres which you can then match up to the aquarium filter.

Remember, its too easy to under filter and aquarium but difficult to over filter an aquarium. Its always better going for the higher rated aquarium filter than a fish tank filter either just big enough to cope or too small.

Not using the correct size filter will only result in poor water quality, stressed fish and problems with your aquarium.

Internal Filters are as the name implies filters which are housed inside the aquarium which circulate water inside the tank whilst pushing water through the unit which contains filter sponges, carbon and other media such as phosphate removers or bio – media. Internal Fish tank filters are normally associated with Internal filters up to around 200 litres. Although there are some much more substantial filters available such as the Juwel Internal filter system which come as standard with all Juwel tanks.
