Nature2 comes with an adjustable stick so you can have the canister in the middle of the filter. It doesn't affect water flow much. If it is a concern, some people just lay the canister in the filter compartment.

With the "goodbye Bromine" comment, I just want to be sure you know that you still need to use a santizer (with N2 -- dichlor, the Frog works with Bromine or dichlor). IMO, the folks that use N2 with daily MPS and only occasional dichlor are asking for trouble. You need regular doses of sanitizer to keep a clean tub.
