Im looking to get an oxygenation kit (not a pump aeration kit) and wondering what people like most. I know williams brew has one for $55 with a SS wand and 2 micron stone, but for what I have read they have really shotty regulators that can leak and empty a tank in no time. I was wondering if the wand really made a difference or just attaching it to tubing has enough weight to keep it down at the bottom of a carboy.
