Strawberry Kolsch poroblem, or not?

[Bussy]

I'm currently making a Kolsch and added stawberries to the secondary. It's been two days and I have not seen bubbles from the airlock. Should I worry? Shouldn't fermentation start over with the sugars in the strawberries? Thanks for your input.

Sometimes your airlock isn't totally sealed so you don't notice. Other times the fermentation that kicks back up is hardly noticeable.
