Air lock bubbles

[nordoe]

So I am on my third batch of homebrew and decided to brew a big beer. Chocolate cherry stout and used 2 packs of london wyeast. The bubbles are actually coming out of the air lock onto the lid of the fermenting bucket. I used sanitized water in the airlock and it is now turning brown. I am assuming it is foaming actually coming up the hole. Is this bad? What can it do to my brew?

Its fine. Pull it out, clean it out, reinstall with fresh water/starsan solution.

brew's fine. you'll want to hook up a blowoff tube to give the krausen somewhere to go. Ceilings have been painted due to an explosive release of pressure.
