I'm employed by a lake association, and a few years back they had a nano-bubbler system put in. It's the same type of setup used in the reflecting pool, though those ran on ozone while ours just uses a reactive oxygen species. A reactive oxygen species is basically an oxygen molecule carrying an extra electron, whereas ozone has an extra oxygen atom. I pushed back against it quite strongly, since it's honestly nothing but snake oil that causes more damage than benefit, and the promises made about it outright violate the laws of physics. Sadly, they managed to get it approved and we went ahead with the installation. Fast forward 3 years, and our lakes became pea soup since Cyanobacteria can easily consume oxidized nutrients. Exactly what I had warned them about from the start. So the downside is it set us back 10 million dollars, but the upside is that through all of this I publicly embarrassed a whole team of scientists because my calculations were correct and theirs are now shown to be wrong, and I earned a great deal of respect from the community along the way. Plus, it's a very affluent area
