Re-hydrated my US-05 this time instead of sprinkling the dry stuff. Really happy with the nice active ferment that I am having. My experience so far with 05 is that it is the tortoise where the other Fermentis yeast I've used S-04 is the hare. The problem is I waited the prescribed 3 days. My krausen dropped a bit and seemed stable and I switched to three piece airlocks. The next morning, my airlock is fouled with krausen and I have to monitor it all day to make sure my airlock doesn't boil over. Is there any good reason that I should switch to the airlocks or does the blow off tube set up do exactly the same thing except with less need to worry? I saw the setup at Lumberyard in Flagstaff AZ and it looks like it is basically a big blow off tube.
