Thanks for the compliments everyone. I've seen so many questions regarding how to clean Classic filters & which parts are which, so I thought this would be helpful.
JustinChase, Welcome to MFK! There are a lot of great people here that are willing to answer your questions. You should be fine with the filter cleaning as long as you alternate cleaning them.
Zerojquan85, the 2213 comes with an insert that holds the media. The 2215 & 2217 do not. The disadvantage to using media bags is that they will allow some 'bypass' around the bag as it is difficult to conform to the shape of the canister. I ONLY use the media bag for my bio-media. BTW, you can now purchase lattice screens for the 2213 if you want to eliminate the insert. People that have done this have noticed an increase in the output flow. Hope this helps.
Yanbbrox, it is always an excellent idea to keep the bio-media submerged in tank water when servicing your filter, step #9. I have well water with no chlorine or chloramine but sometimes I do forget to note this when I respond to a question. As for the mechanical media/pads, they can always be rinsed in a dechlor product solution after cleaning with city tap water.
