You shouldn't ever doubt Yooper.....
I actually don't own a blow-off tube which has never been a problem in the past. HOWEVER, I brewed on Saturday and went downstairs yesterday to check on the brew. I noticed that I was close to the top with Krausen bubbles, but thought nothing of it.
This morning, my airlock was almost full of yeasties and krausen. I quickly though of ways to create a blow-off system. This is what I did.
I installed an old airlock without the movable plastic peice and the top. I attached a 9/16th tube to the inside of the airlock and put the other end in an old milkjug type gallon jug with water. I then attched the airlock to a stopper and put back on my carboy.
If I hadn't been in a rush to work, I could have devised something better. Do you think I"ll be ok with this? In my haste, I did not sanitize the jug or the tubing, but did sanitize the airlock. SHould be ok, as it was fermenting for about 2 days before I did this. Never had this much bubbles and Krausen before!!!
