The Atman Canister filter is made by the same factory that makes the AquaOne, however it is not the same as the AquaOne CF1200. This one is way newer, more powerful, and comes with push to prime. (The AquaOne CF series is an old Atman EF series)
Looking at the pics it looks like the aqua one has the exact same circular spot on the top where the UV bulb is in the atman but apparently it's not included??
