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. 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.
