Your cycle is looking like it's just about done so it won't be long.
One more thing, I think you should have some sort of ripple on the surface you need at least a little oxygen exchange.

If you think about it, the increased gas exchange to some point is a function of surface area...by increasing the surface area of the tank, however so slight, you're helping increase gas exchange.
Here's a really interesting link to an article called "Turbulence and Wave Breaking Effects on Air-Water Gas Exchange" - be warned, it's kind of technical.
http://complex.umd.edu/papers/breakinggas2000.pdf
Although they conclude that : "until breaking waves occur, the primary role of the wave state is to provide a means for transport and mixing
of the surface layer, via turbulence..."
(keep in mind they're talking about the ocean here)
They continue later that: "Once wave breaking occurs, the ingassing rate jumps...The onset of high amplitude acoustic events is correlated with the onsets of wave breaking and broadband spectra in the wave height. There is also a corresponding increase in O2 absorption rates."
so, if increasing breaking wave height corresponds to increasing 02 ingassing, then certainly ripples on the surface of a body of water would be more effective at gas exchange than no surface movement at all.
