You'll need to add your own biological media and cycle it (in keeping my media for the new filter sorry). AND you'll need some new hoses.
All the ones I had are disgusting. I recommend you replace those short connective bits between the filter and the double taps too. You need 16/22mm hose for the intake and 12/16 for the outflow. No manuals but they're still available to view; download from the manufacture website. The item "Eheim Classic 600 2217 External Canister Aquarium Filter" is in sale since Monday, February 11, 2019.
