Big Al's sells Eheim filter media. As for non-pad media you can use Hagen,
Eheim or any other brand. They main thing is that the media provides a
larger surface area for a bacterial colony to propagate. If you're really
not certain, then give Eheim a call or email. I've found their post-sale
service to be quite excellent.

Ok, so I went out an purchased the canister filter of my dreams.
Bought it on Ebay actually. The problem is that I've never had a
canister filter and don't know exactly what to do with it. I need
media for filtration but what do I buy? It should be here about
Wednesday or so and I'd liek to have everything I'll need handy so I
can set it up right away.
