[COHO] Oxygen tank

[J Shilling]

I just use a fish tank bubbler and stone for 15-20 minutes.  I have had no 
bacterial issues and extremely quick starting fermentations.  This is also 
what got my past having my fermentations stall out in the teens to getting 
them as low as 1.06!  Mind you I always seem to brew stuff around 1.60 or 
higher so it takes an excellent ferment to get that low.  I swear by my 
little fish tank bubbler.
