As a general rule for a mixed carbon\/zeolite\/sponge cartridge in a small starter kit filter: rinse the sponge in removed tank water at each water change to clear debris, and replace the whole cartridge once flow visibly drops or the carbon and zeolite stop pulling out odour and discolouration — carbon and zeolite are consumed and don't recharge, even though the sponge itself can be rinsed and reused for longer.
