I set up my co2 diffuser a couple of days ago and I'm having issues with the bubbles escaping around the cap instead of passing through the ceramic diffuser, the lid is passing next to no bubbles and its just working its way around the thread and out as big bubbles instead. I cant hand tighten the lid anymore and I'm not sure what else to try? anyone else had this problem? it cant be the diffuser being clogged as its brand new.
