As a general rule, mechanical foams should be replaced or rinsed regularly to stop debris clogging your filter, while biological media such as ceramic rings or bio balls should be left largely undisturbed once established, since this is where the beneficial bacteria colonise and do the real work of breaking down waste. When choosing replacements, match the foam density and media volume to your filter's chamber size and your tank's bioload, rather than simply buying the cheapest fit. Staggering media changes, rather than replacing everything at once, helps keep your filtration steady and your aquarium looking its best all year round.
