Hey everybody. Got yet another question. So I bought a oxygen kit to put oxygen back into my wort after a boil. All I need is the oxygen tank. Saw a tank at Home Depot. But I look at the bottle and it has all these warnings on it. Ie. Only to be used for welding and contents under pressure. Are these normal warnings? Can it be used for brewing oxygenating purposes? Or am I being to paranoid?
