D'oh! Overflowing carboy, bubbler shooting streams of foam all over the walls!
I didn't want to take the top off and get more air in with the wort but it was going crazy. I guess I put too much water in the carboy. I cleaned the air lock and put it back on it started bubbling even more. More streams of foam squirting everwhere. Argghhhh! Its slowed down a bit now.
Did I screw it up with more air? If not I've got a tube top thing I can use as an air lock instead. Thanks for your thoughts on batch two.
Thanks! Put the other top on with the hose into a gallon milk container 1/3 filled with water. That makes sense that while some air gets into the wort it is pushed right back out by the co2 once the new airlock it on. Got it.
And yes it's a five gallon carboy filled to the shoulder. I guess I got the wrong one as these begginer kits all seem made for 5 gallons.
