Foam in airlock on top of carboy (plastic)

[Tobor_8thMan]

Blow off tube. Needed when I brewed a cream ale and table sugar (table sugar was part of the cream ale recipe).

Vigorous fermentation.

Hello all,

I'm a first time home brewer, so all this is new for me! Prepared my first batch this weekend, and this morning the fermentation process has apparently started! I noticed that the airlock on top of the carboy is having "foaming bubbles" should I remove? Can this impact or even contaminate the fermenting in progress?

Ok, I caught this overflow just as it began to erupt. Hopefully I have followed advice from here all ok and it’s just a case of stout sitting for a few hours until it peaks and I can pop the S lock back on

There is no need to switch from a blow-off tube back to an S type airlock they both serve the same purpose, I use only blow-off tubes for EVERY batch. I have had blow-off at times with all styles of beer. BTW if you can have the catch vessel below the fermenter to avoid a reverse siphon. At least have it on the same level as the bottom of the fermenter.
