For larger fish tanks with lots of fish we recommend using one of our External Aquarium filters.
These are designed to hold much more filter media, for larger volumes of water filtration. These filters are far more effective than the Internal Filter types and are easier to clean and maintain too.
Some models also have the added benefit of in-built UVC the best in clean and clear aquarium water.
