That's all I use. I have a brewbucket primary and those like Primo-Water 5 gallon blue jugs from walmart/lowes. I've never bulk aged in them exactly but I had some that insisted on bubbling slowly for like 4 or 5 months.
I'm a science teacher so I'm going to swipe a dissolved oxygen test kit, boil the oxygen out of 5 gallons of water, seal it up in one of those jugs with a bung and airlock and test it a year later. See what I get.
