So this is my second brew. first one came out great. While I was boiling the ingredients I broke my thermometer. Since it was Sunday there was really no where I could go to get a new one. I put some White Labs liquid lager yeast in the batch and Im pretty sure that the temp was over 75 degrees. Its now 24 hours later and the only visible sign of anything happening is that water from the airlock is actually being sucked into the fermenter. As soon as I put more water into the airlock it immediately gets sucked in again. Instead of pushing air out of the airlock my wort is sucking pressure in. The airlock is fine, Ive tested it. Anyone have any idea what has happened here?
