I bought a pair of used Eheim Classic Filters. They just got here.
Inside the 2213 was first this white fuzzy cotten like pad. Then its looks like almost various pieces of white gravel looking stuff. Mixed in are these little tubes that are hollow, looks like they are made of the same stuff.
Closer to the bottom there is something black looking, haven't pulled it out. The bottom is almost all full of hte hollow tubes.
Does this sound right for a Eheim 2213?
