I am looking for a better oxygenation stone and found a 2" one made from Sunleaves. As is was “Quality Manufactured in China” I am hesitant to put it in my beer. So if anyone uses one of these and hasn’t grown a third arm I’d like to know.
I don’t know about those. Not because of the China thing, but because there is not mention of the material. You really want a stainless steel stone. Stainless is going to be completely inert (300 series is typical) and all metal construction can be boil sanitized, which is a big plus and helps unclog it.
I’ll never go back.
I don’t know about Sunleaves, but this is a good one: http://www.williamsbrewing.com/22-AERATION-WAND-P490C106.aspx
I’ve been using it for years without issue, and you can boil it. The stainless wand makes it really easy to use.
+1 to this one. I have been using for about a year and works great. Also agree that the wand makes very easy to use.
