I've been brewing this cider for 8 days. It was going smooth and had a lot of krausen so I took out a bit two days ago, but now it has passed more than 48hh and I was expecting some more krausen or some more movement, but even the airlock has nearly stopped bubbling now.

Did I kill my cider? What should I do?

(I have a 6L plastic carboy, and used 3,5g of champagne yeast(bioferm champ))
