External filters are an excellent option for medium sized aquariums and upwards. Their large size and power means they are the most suitable option for larger aquariums, or those that are heavily stocked or house messy fish which produce a lot of waste. Excellent for aquariums housing large and/or big groups of cichlids, carnivorous fish species, oddballs, stingrays etc. They are also a great option for those who wish to invest a bit more in a filtration system in order to cut back on aquarium maintenance. A larger filter means larger surface area for beneficial bacteria which means more waste can be broken down. Being an external filter there is no large unit that sits inside the aquarium itself, just some intake and outlet pipes, this makes it easier to create a more natural aquascape and also gives your fish more room to swim! It is worth remembering the clean out your filter impellor regularly in order to keep your filter working to its full potential.
