Aeration Stone Causes Foaming

[Steven Barrett]

I have an aquarium pump and aeration stone that I’ve tried to use to aerate wort for a few batches and after a minute or so the foaming is so excessive I have to turn it off or foam will overflow. Has anyone else run into this issue? Am I doing something wrong?

You're not doing anything wrong. Wort just foams when you bubble gas thru it.

Brew on

Thanks @doug293cz. More specifically, I would like to aerate it for longer but I can’t due to the foam generation.
