My second batch of "warranty voided" JAO is clearing well. At about 5 weeks in I noticed that the water level in my airlock dropped substantially. I topped them off with boiled then cooled water and the level has dropped again and I see water in the stem that goes into the carboy. It is as if the water is being sucked into carboy. Any clues as to what is causing this and what I can do about it will be greatly appreciated.
Thanks in advance,
