Do not fret about the canister filter, I've used them exclusively on reef tanks in the past with no problems, your filter is just fine
As another member said, I would look into a larger water change and possibly run a little carbon and GFO (Granulated Ferric Oxide) double check your temperature settings; also if possible try another test kit.
I am running carbon and gfo I stated that in my post.
