Hello everybody,

Quick question - is there a schedule or anything for when to perform maintenance on an eheim 2026. How frequently am I supposed to wash/change the sponge, medium, etc. If there is no rough schedule, how do I know when to perform the maintenance?

Thank you!

P.S. - does anybody recommend the optional carbon layer?

When do you actually replace the "hard media" (and what percentage) ... or is rinsing enough.

Thanks for the help
