Lots of yeast activity, nothing in the airlock

[Justin Davenport]

Hello,
I just brewed a DIPA (all grain) and 36 hours after I have no activity in the airlock. I can see lots of activity in the fermenter itself - particles swimming around like crazy - there’s a real party going on in there! Just nothing in the bubbler. Anyone any ideas what, if anything might be wrong?
Thanks in advance

Your lid on your Fv isnt airtight. The C02 will find the easiest escape route. Doesnt matter though, I've never used an air lock and just cover my FV's with cling film held on with an elastic band

Simple way to check, press down on the centre of the lid and see if it bubbles. Sometimes it takes a bit of effort to get going, especially if there is a lot of water in the airlock.

Turned out to be a cracked bubbler!!!
Pushed it all the way down and Bob's yer builder
