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.

FAQs
How often should I clean the filter?
Clean the filter every 2-4 weeks, depending on the bioload of your aquarium.
How often should I replace the filter media?
Replace mechanical filter media when visibly dirty. Replace chemical media every month. Biological media should be rinsed in aquarium water, not replaced unless damaged.
How do I prime the filter?
Follow the priming instructions provided with your specific filter model. Usually involves filling the filter with water and initiating the pump.
What type of filter media should I use?
Use a combination of mechanical (sponge), chemical (activated carbon), and biological (ceramic rings or bio-balls) media.
Why is my filter making a gurgling noise?
The gurgling noise is usually caused by trapped air. Try tilting the filter to release any trapped air.
Can I use this filter with a saltwater aquarium?
Yes, but ensure the filter is specifically designed for saltwater use, as some materials may not be saltwater-compatible.
How long does the filter last?
With proper maintenance, a Fluval External Filter can last for many years.
