Those are both pretty bad ass. Not sure how the hydrogen gas/ electronic gadget that separates the molecule would effect microbes tho? The first one might be better for teas but supposedly you wanna avoid any mechanical pumping action cuz it chops up fungal hyphae but is fine for bacterial breeding. Not sure if that would do the same tho. Have you tried ceramic air stones? They're very pricey but are self cleaning ,create finer bubbles , they use them in fish farming

I may have found a way to hack it...
