Not sure how a spray bar would add aeration unless it was above water level and the salt spray would be quite a mess. A spray bar
in a sump is a different story.
My first tank was sump-less with a canister filter, even after researching for a year I still bought unnecessary equipment, was all part of my own learning curve.
Running GFO passively in a canister filter is not as effective as fluidizing it in a Phosban reactor.
One other advantage of an overflow is surface skimming, removing the film that builds up on the surface of the water. Eheim probably has a surface skimming attachment for your canister.
