um, i use the morebeer.com one which I like. I was just recently on the williams brewing website and noticed that there's has a long metal tube that's attached to the oxygen stone which I personally feel is probably better then the morebeer one since you can actually clean the tube.

You just have to go and pick up some o2 tanks at the hardware store but there like 7 bucks each or something.

A Mixstir and a drill is every bit as effective in results as an expensive O2 system.

I just got the one from williams.
Haven't used it yet but I liked the long stainless tube since it will keep the stone on the bottom and let me control where it is.

Picked up O2 bottles at home depot.

I bought the Williams Oxygenation Kit a couple months ago. My beer quality has improved dramatically. Consistent results, always reach FG. One of the best pieces of equipment I invested in. That and the little welding o2 tanks at Lowes.

Not true. The most vigorous air-only aeration system (mix-stir, aquarium pump, venturi) can only get you up to about 6-8 PPM dO2 and that takes a lot of darn work with air only. A minute with pure O2 and you're at the optimal 10ppm dO2. Plus, that mix stir is almost twenty bucks, and that's if you already own a drill. For forty more you can be using pure O2.

I bought the Williams aeration wand and it worked well until one day when I started oxygenating my wort, somehow pressure built up and literally blew the stone off the stainless steel wand. Another issue with these is a friend of mine traced two infected batches back to the aeration stone. Make sure you sanitize!

I was able to fix my stone by putting a spare rubber o-ring on the wand and gluing the stone to the ring.

I use O2 because it ensures that fermentation starts quickly. I do starters of the appropriate size and oxygenate so that nothing else has a chance to take over the wort but my yeast. I usually see fermentation sign in a few hours and have blow off hose activity within 3-4 hours max. Fermentation is usually vigorous and appears to be efficient. I also ensure I feed the yeast nutrients while doing the starter. All these steps have improved the quality of my brews.

Sanitizing the stone and wand is just a matter of soaking in starsan I suppose...like anything else? Maybe soak longer than other items since the star san needs to get into the stone.....???

Based on results, it's equally effective. If it wasn't I would have stopped using it yeats ago.
