hi.
I have a question on the media for canister filters. I plan on getting the Eheim classic 2213 filter. The media does not come with the filter so I dont know which to get. For mechanical filtration should i get course or fine media? what do I do about the biological filtration? Do I get bio-balls and just throw them in there? Am I suppose to layer the media in a special order? or can i just throw each layer of filtration on top of each other?
