This article says to switch out bio-media every three months which I do not agree with, everything else is on spot!I have seen references to a broken link on how to back flush a Eheim classic. Does anybody have a working link or can describe the process?
thank you

Hmm I though it was there. As far as I know backflushing is a common thing to do with the classics.Yes, the Grigg article seems to have edited out the back flush potion of the original article--maybe its not standard practice to do so anymore. I guess you are of the school that rinses out the media rather than replacing it? I would rather do that.
I rinse all at once in tank water. Just make sure the media bag is big enough, you don't want any water bypass...Obviously you rinse it in tank water. Do you rinse all of it at once. I was thinking of putting it in a media bag for easy moving?
