What works better in the long run is to rinse out the media each time you do a water change. That way the filter never really plugs up and the biological filter just keeps on working rather than going into the trash.

Sorry, I should have been more specific. I was speaking more about mechanical filtration. I thought this was the same thread that I explained about biological filtration. Lol. I got confused replying to too many different threads.
Oldman is right. Internals will serve as biofilters. But no more so than a cheap sponge filter or even a box filter. but then again, because bacteria will grow in just about any surface, even without the I ternal, bacteria would grow in your substrate and provide the same biological filtration. But that's another topic all together.
What I meant to say is that internal filters provide no mechanical filtration, and are not great for what they are. You are just as well off with a sponge filter powered by a powerhead. And at a fraction of the cost of an internal.
Sorry if I confused anyone. I should have been more specific.
