Stability is a key element to pretty much all fascets of aquatic gardening, this is also where EI has an edge, but I suspect that Co2 misting tends to accelerate or "augment" Photosynthesis in closed system enviroments. Dissolved Co2 is all well and good, but atmospheric Co2 tends to lubricate the process considerably. Plants have a clear advantage over algae in the right venue. Misting may not occur naturally, not often any way, but we often take advantage of biological phenomenon in this hobby. If it levels the Algae playing field a little I say go for it ! 10,000% availability is quite an edge and higher plants evolved to take full advantage of that.
