Need some help please. Brewed a beer Oberon clone. It has been in my secondary fermentor for about 3 weeks. It was settling very nice when last week it started to get what i would call foam or a head on it and it now covers the whole top of my beer. Is this something to be concerned about? Thanks Please don't be to technical with your answer as I only do this for a hobby.
