Default cheapest way to go pure-O2

I've started to make some bigger beers, and even with a starter of liquid yeast, I think my results would be better with aeration (I'm currently not doing anything on that front)

I see the 2-gram oxygen cylinders at Home Depot for $10 - how many 5-gallon batches can I aerate with one of those? I assume they are just disposable like a propane camping tank?

Also, do I need to get the Williams Brewing aeration kit w/ diffusion stone, etc? I heard Jamil on the Brewing Network say that most of the gas goes into solution due to disturbing the surface, not due to the tiny bubbles. Can I just get some some of stainless small-bore wand to pump the oxygen into the bottom of the carboy?

Do these cylinders require some sort of regulator like a C02 bottle, or can I just run it full-blast for 60 seconds?

I bought the O2 kit from Austin Homebrew and got my tank from Lowes. It was a little more than I wanted to spend, but it was worth it. My fermentations have all attenuated as much as the yeast will allow and even a little more in some cases since I started this. I have done 5 batches at 5 gallons so far with my O2 tank..

Aeration is very important and you should take it seriously. It helps the yeast multiply for a vigorous fermentation that overtakes any infections and avoids stuck fermentation later.

The Williams kit is what I use and I highly recommend it. The stainless steel wand makes it very easy to get the stone down in the bottom of the bucket/carboy. Otherwise you are pushing on a floppy hose that wants to curl around and come back up. It comes with the regulator valve you need.

You don't need to blast the O2 for 60 seconds. A gentle fizz (think about it - any bubbles rising to the surface are not going into the liquid) for about 30-45 seconds is all you need. At that rate, one of those red O2 cylinders will last for 7 or so batches including starters (which require maybe 15 seconds). I did find a Benzomatic 2.1 OZ (not gram) cylinder at TruValue Hardware for about the same price as the smaller one in the big box store. It claims to have 50% more. I have not used enough of it to tell how long it will last. I write the batch number I start with on the bottle so I have a general idea when to pick up a replacement.

The plumbing type bottles are disposable. I have tried to find a local supplier of O2 in greater quantities (medical or welding) but haven't had any luck yet. Maybe someone will chime in with a way to tap that source.

.
I'd like to get that wand some day, but for now I just zip-tie a SS spoon to my air stone to give it enough weight to drop down to the bottom of the bucket.. It works great!

Also, scour Craigslist for someone selling medical O2 tanks. I kept looking once a week and eventually found someone near me selling two full tanks (including their regulators) for $50, and I had to spend $2 to modify my wand (from William's brewing) to make it work with the new tanks. It was kind of a large expenditure up front, but it beats paying $10 for the tiny tanks from the big box store.

How much does it run to fill the tanks? And what size are they? I was only brewing about once a week when I was in Texas, but I had one of the bottles from the box store last for years.

I just put 1 oz of oxyclean into the wort before I pitch the yeast. That creates oxygen when I dissolves. Works like a charm and is cheap.

Wow, really?? Simple and cheap, but safe? Does it affect the taste? Cool
