This is my first time using a blow off tube; as well as a yeast starter and aeration (hence the need for the blow off tube!).
After the about 15 hours the airlock had foam and “stuff” coming out the top, so I replaced it with a blow off tube. Man did it bubble like crazy!
Now (about 40 hours after pitching) the bubbling has slowed significantly.
Should I put the airlock back on? Or just leave the tube in until I rack to secondary (or bottle)? I know that theoretically there is a risk of contamination for the few seconds it takes to yank out the tube and put the airlock in.
Thanks in advance!
