Krausen clogging your airlock and blowing up your buckets? Get a blow off tube! Attach near where you would normally put an airlock/bung and put the other end into a bucket of water to create an airlock and allow a place for air and krausen to escape.
1" ID / 1 1/4" OD Tubing for use as a blow off valve. Sized to fit perfectly inside a the mouth of a glass carboy. Pre-cut in 5ft increments.
Alternatively, it's a little difficult but you can usually stuff a 3/8" tube into a normal sized airlock hole (whether it be in a lid or bung) and create a blow off tube that way.
