I do like the puzzle, and the artical is very interesting but it gives no explanation on how they get it to stay stable for 70 days or actual DO levels relitive to water temp It doesn't make sense and I can't find any other info on nano bubbles staying suspended in water. How does gravity not effect this? How does the water temp not effect this ? Do you have any more links you were reading? I'd happily buy a nano bubble generator and do some tests if there not crazy expensive and I could find some info that supports 70f water can hold more than 9 ppm DO. Thanks for the links
