    Just wondering how often each section of media gets changed. Also if anyone has any tips for this particular filter.

    I don't change any of the biomedia unless it's falling apart, but I make sure to seed new biomedia for 3-4 weeks before throwing away the old stuff. The mechanical media you can change when it starts to fall apart of gets too clogged, otherwise you can just clean it in old tank water weekly to monthly or so.
