the75 said:I like the paint mixer idea attached to a drill. I tried three different ways, shaking my carboy, aquarium pump with in line sanitary filter to a stainless steel diffuser, & finally an oxygen tank directly to my stainless steel diffuser. They all work, but the oxygen is the easiest & fastest acting by far. I bought an oxygen tank from a gas supply company (small 20cf bottle) as well as a regulator with a ferrule that allows me to attach a hose to it. I sanitize the diffuser & the hose, drop it in & blast my wort for 30-45 seconds, done. The first time I used it, my fermentation began within minutes & it was aggressive. Here's a video of it:

Williamsbrewing.com oxygen aeration system with the wand, stone, hose, and regulator. Well worth the price IMO.
Those dont have a filter?Or need a filter? And how much are those oxygen tanks at hardware stores? Do you only aerate it once at first or do you keep it in and aerate again (think i read something about that) ?, after a few hours or hour or whatever?
