I was reading an old past issue of Thge Aquatic Gardener(TAG) where Diana Walstad has measured the CO2 in one of her tanks with a siesta and like my predictions suggested why the siesta methods works for some(those with moderate CO2 limitations, too low CO2 bubble rates etc).......the data supports my contention in her aquarium.
Upon turning off the light, the CO2 rose back up quickly.
In aquariums where the demand for CO2 far out strips the supply, even if enriched or steadily added.............this method works well to deal with algae for some hobbyists. However, for those with good CO2.........it has no effect.
Thus we can say that the siesta method has dependence on or limiting CO2. While for those were it does not help..............the CO2 is independent of other factors.

Ole has a good article in there as well about gas flims (and this may be why perhaps..........water changes allow the plants to grow much better when the plants are exposed)
Dupla's Optimum Aquarium(1986) also discussed the high CO2 content in the tap water in Germany, which is likely true for many worldwide.
