If yours is simply annoyed from the irritation, as alasg001 suggested, then give it another couple of days. However, if it's not coming out by Saturday or so, you might try bumping your alk up to 8-9 dKH and see if that helps.

Yea ... DKH was between 9 and 10 and then I added about 60 lbs of dry rock to my tanka few weeks ago. I've upped the B-Ionic since. I'll keep my eyes on it.
