For your reef tank, if you really want to use the canister, personally, I would remove any of the floss and or ceramic rings/rocks that are generally used in those things. Use it only for carbon / phosban etc, (these are items you need to change frequently anyways).

You are much better off sticking to your small (depending on how small they are. I do 10% weekly on a 34gal) weekly water changes and regularly cleaning your skimmer so it produces consistently.
