Never heard of it. I guess some one on oxy for health should of tried it by now. The more oxy you can get in the water the better but like lord says might not be the bang you want. Oh it's carbon dioxide you really want the room full of. Seems like you would want C02. It would keep the water temp low and fill the room too. You would nee meters and a good ventilation system for the room. C02 would be dangeruos in a living space for peeps. Give it a try and let us know. My dad is on oxy the house stays full. I also know people who walk around with those portable units smoking cig's and don't blow up.
