    All you need to do is give the media a swish in old tank water to remove any large pieces of debris & clean the impeller if that looks gunked up.
    You don't change the media unless it's falling apart or you'll lose all the beneficial bacteria, the only thing that needs replacing every 3-4 weeks is carbon if you use it.
