I have been aerating with pure oxygen using the oxygenation wand from William's for the past four beer batches. In that time I have gone through two disposable O2 tanks. William's says one tank should last me 20-30 batches. What the hell am I doing wrong? I turn the valve until I start to hear the air flow, then I aerate for 60-90 seconds. I don't open the valve all the way, and I have never left the valve open. Am I just buying lousy tanks? I bought Worthington brand 1.4oz. cylinders from Home Depot.

You need to remove the regulator after each use. most of them touch the pin enough for a slow leak. I just had one drain on me.

different brands of O2 tank seem to matter.

I have this same problem. I seem to go through 1 tank for every 2 batches(5 gallons). I do not leave the regulator on the tank when I am finished using it.

Misery loves company! What brand tanks do you use?

Huh! That sucks. I leave the regulator on and get at least 8-10 batches per tank. Same Worthington tanks from Home Depot.

I push the tip of the wand against the glass softly and watch it when turning it on to make sure it isn't just shooting out of the tip. There is a huge difference between it barely coming out, coming out a good amount, and it coming out a ton. I try to shoot for enough coming out that it is fizzing out of the tip and causing a foam at the top of the wort but not rolling the top of the wort like a boil would.

I also only go 60 seconds. My first tank didn't last 20-30 batches...probably only 6-10, but that's an improvement over 2, haha.

I had this same issue. I'd get 2 batches out of a 1.4 Ounce tank even after "calibrating" (basically, I marked the knob and reg body) my regulator by guaging bubblage in a glass of clear water. Turns out, my reg creeped. I only learned of this after I bought a flowmeter.

Since thios discovery, I stored the reg away in a dusty box and replaced it with a dual stage welding reg (capable of holding a 1psi flow rate) for O2 and a RO tank. Pricey? Not after I sat down and figured out how much I was wasting through the previous method.

I'll take a look at the reg when I get back home. I don;t actually know who makes it. Basically, I told the counter guy what I wanted and bought what he suggested. The regulator alone was around $80.

This one is similar in looks tho (not that, that matters) http://minority-one-inc.amazonwebsto...source=froogle

and here are some bidable offerings (not mine); http://shop.ebay.com/items/?_nkw=2+s...tors&_osacat=0
