The Magnum 350 isn't a HOB filter. It hides under the tank and doesn't have a biowheel either. Just a long suction line and a directable discharge. It is also clear so you can see how nasty the filter is without opening it up.
There is a Magnum HOB with a biowheel, and I completely agree that that would negate the point of the canister.
I stand corrected. Was thinking of the wrong filter.
