Stout stopped?

[Popspicker]

The coopers Irish with extra roasted barley, choc malt and dark malt that I started on Tuesday night (Sat morning now) doesn't seem to be bubbling anymore.
The initial stages were very vigorous and the krausen is still 2'' thick on top.
I was just concerned because the bitter I did last time still bubbled after 10 days.
The woman at the LHBS did say there was a lot there to ferment and gave me a spoonful of white crystals that I did put in with the yeast.

Would it be worth me taking a reading after only 3 and a half days by the way...could it have finished fermenting after such a short time? :wha:

patience m8 take a reading if you must to find out what its at but either give it a stir and leave it a week and a half, check your temperature aswell but be patient just because it aint bubbling doesnt mean its finished fermenting hope this helps :thumb:
