sorry just have to disagree with honeythorn there for a moment, im sure this is what she meant but didnt explain so well
Depending on what filter you have, and what filter media you use in it, some media you can take out and change weekly, white filter wool for example.
BUT things like ceramics and sponges should be left in the filter and not replaced as this is where your good bacteria live. (even though in your instruction booklets it may tell you to replace them every so many weeks, there really is no need unless they are very old and dropping to pieces ) if they are looking grubby, take a small amount of tank water in a bowl (NOT tap water) and rinse the sponge about in the bowl (not too much, just swirl it round till the big bits of gunk come off) then replace. never rinse it in tap water as this will kill off the good bacteria.
