Oase

An unpleasant task for many aquarium owners is often the filter cleaning – in addition to changing the water, this is one of the most important and most frequent obligations. Cleaning‐ and replacement cycles for filter media, such as filter foams or active charcoal, depend on tank size and animal stock. Should it really become necessary to replace filter medium, OASE recommends that you undertake the replacement incrementally, for example first replace one of multiple filter foams, after two weeks replace the next one, and so on. The reason is that the biologically active microorganisms that have settled in the filter, settle in the filter media. If you replace everything all at once, the filter will not be completely active for several weeks, because regrowth of bacterial cultures takes some time.
