Im pretty new to homebrewing. This is my second batch. So on the third day of ferm. i had the carboy in the closet and it was getting too cold, so i moved it to about 10 feet into warmer air. The top was very foamy before the move. about 10 hours after the move, when i checked the carboy all the foam was gone. There was still alot of action coming through the overflow but no foam on top of the beer. Is that supossed to go away, or did the move have something to do with it?
