I cannot speak from personal experience, but one of the authors of the
"Optimum Aquarium" (Dupla) provided a graph in one of his subsequent books
that showed the O2 level in one tank with and without a trickle filter.
If I remember correctly, the spikes in the graph were of similar magnitude
you describe without the wet/dry. With the wet/dry connected, the maximum
was the same, but the minimum was much higher. The over all curve went from
"spiky" to "smooth" as well.
If someone wants me to dig out all the gory details, let me know and I'll
get back to you.
in frosty Southern Ontario. February came early....
