It's just a guess on my part but I was sort of hoping that with the combination of zeo and these, that the addition of the bacteria to the reactor would explain this.
It does mean that I don't know if it's the zeo or the pellets responsible or if it's both. I don't have a way to quantify how much reduction is attributable to either.

Maybe. One thing the pellets are good for is sloughing off a bacterial film which the manufacturer claims is good coral food. A sponge on the output or a filter sock would impede this, or possibly get clogged.
Zeovit also makes this claim.
I have noticed that when I agitated the reactor that more of this film is released than when I was running zeovit before on its own. So there seems to be some truth to this aspect. Whether it's as good as they say it is for corals though, ... too early for me to speculate on.
Having mixed the two together though ... I do have a problem down the road when it comes time to replace zeolites. The pellets don't stay put as a layer on top, the agitation fully homogenizes the mix so I'll be picking out zeolites one pebble at a time when the time comes. We'll see how much I hate that. Putting a sponge in the chamber to separate the two substrates seems defeating. So I still wonder if in the long run these are better off in their own reactor, or passive in a high flow area in the sump in a loose filter bag. But we'll see how it goes.

The manufacturer claims no need to replace the pellets but just let them slowly dissolve, theoretically dissolve into nothingness over 6 months. So the plan is to keep the pellets but just pick out the zeolites.
