So I started an apfelwine brew yesterday, and I used starsan solution in my airlock. After checking on it today,m the fermentation is coming along great, very vigerous, but it's pulled some of the starsan foam from the airlock back into the carboy, and the foam from the apfelwine has turned the solution in the airlock yellow.
Should I change out the airlocks fluid? Will the starsan foam in the carboy hurt anything?
