What Is Mulm?
Is the red gunk in my filter mulm? I've never exactly known what "mulm" is, but here I have this red/orange..stuff that covers my filter pads and the filter internals from top to bottom between water changes. It almost looks like earwax. I never got this accumulation until I set up the Eheim Liberty filter.
