Dude where are you coming up with this stuff? How is oxygen UNABLE to dissolve while inside thousands of tiny bubbles being pushed through water, but somehow it can be forced downwards into the water?
To the second post, explain to me how smaller bubbles(more surface area) allows water to hold more oxygen. It speeds up the rate of dissolution, not the solubility. And increasing rate of dissolution does NOTHING if you've already reached maximum dissolution, which we can all agree is SUPER easy to do in a 5gal bucket.
To the last post, yes flooming gets the highest DO levels of any method, but as you're not flowing atmospheric air through your water solution at all times, the total oxygen present is lower than with airstones, even though less is actually dissolved. So it works, gets super high DO, but don't say its better than something else when its clearly not.
