I assume you're talking about reverse osmosis water. I had a friend who used to install high end aquariums and she used it. It's also used in wine making quite a bit.

So i wouldnt think it's oxygen free.

No. RO only removes salts/impurities, not dissolved gas.

If RO were Oxygen free you'd have Hydrogen.

I don't think WalMart has the license for that.

Yet.

Yes, but not completely and it's going to depend on a few things. RO membranes apparently have some rejection capabilities against oxygen but the rejection is not that great e.g. about 75% in the case of my system. Thus if the water arriving from my well is at about 4 mg/L DO (which it is) the water out of my RO system is at about 1 mg/L. If your source water has more DO than mine so will your RO water and conversely if your source has less.

When it is poured or shoots out of the faucet I assume it is getting additional aeration, therefore more Oxygen is added at that point. Un-scientific but probably accurate.
