I use the old aquarium pump, filter & stone. I plug it into a timer and run it for 15 minutes every two hours for 12 hours or so. Less, if I make a starter.

Too bad I wasn't homebrewing back when my mom died. She had this O2 generator in her house about the size & shape of R2D2. Now that would have been real HB status!

Since I started using and O2 aeration stone, I have had shorter lag times and no stuck fermentations. I would never go back to any other method, the only disadvantage is that there is a little more to sterilize.

My $8 tank has lasted about 15-20 batches so far. I only turn it on enough for the surface to barely bubble.

My first 02 tank didn't last long at all, but then I learned to go slowly. 30 brews may be a little bit optimistic, but I would guestimate that it's fairly close/

I stir it while it's in the fermenter.... with a wire whisk jammed into a power drill! Oooooh the bubbles!

I have the Williams aeration system too. It works great. I give it a good 90 seconds to 2 minutes. It really makes a big difference over shaking.

The two drawbacks to anything but pure O2 is risk of contamination and much less O2 saturation. If you think about it, whisking or shaking is really trying to get your surrounding air to give up its 21% O2 into the wort (we all know that air is only 21% O2 right?). Well, you're also getting the other 79 % in at the same time which could include nasties. You might have a ton of bubbles but the yeast could care less unless it's dissolved O2. If you think you're gonna brew for a while, an O2 system is definitely worth it in my opinion.

I use an aquarium pump, a hepa filter and a 1 micron stone. Run it for 5 minutes and I'm good. But if you're interested in this system, the review said that it's "Slicker than snot on a glass door knob" What better recommendation could you ask for?

Now where's that box of tissues?

I have a spigot on my brew pot and attach about 8 inches of tubing and one of these to it:

Then let it fall into the carboy. Couldn't be easier and I have excellent fermentations. I also make starters, which to me is more important than an O2 injection system.
