I'm not saying it's right, but that's how it is.
however that being said, an air bubbler or an aquarium jet will add the same amount of oxygen into water, there is only so much that water can retain, and mixing it with the atmospheric amount of roughly 20-21% does the same effect. That's why they flamed you. Plus you need to remember, some of these guys just sit around and wait to flame people, kinda like a weird sport. Don't take offense to it.
the best thing to do if you want really healthy, oxygenated water is to get an established aquarium, with established bacteria and good bio-wheel filters, and use them to water your ladies
