i have an 8 gal fermenter that i use as my primary, and i have used a 5 gallon carboy for secondarys up until this point, but right now my buddy has a batch in my secondary.. he had an extra carboy but it is a 6 gallon, will this screw my beer up? it was in the primary for 10 days, racked to the 6 gallon secondary yesterday and it has a fair amount of headspace. when i put the airlock on the secondary i had a small amount of bubbling occur in the couple of hours after... what do you think??
