Even on all 3 types, you can see that there is a lot of diversity when it comes to filtering media. The best way to use the media you have selected largely depends on the quality of your filtration process. Inexpensive systems which use prefabricated inserts or capsules are not always simple or even possible to adapt in this way. Most indoor and high-end filtration methods allow at least a bit of customization, and cartridge filters, using their multiple media baskets, would be the most customizable alongside aquarium sump systems.
