I'd advise leaving it alone for at least another week. After active fermentation, your yeast needs some time to "clean up" after itself by metabolizing some fermentation by-products. My standard is to never touch my fermenter for at least two weeks, and even longer for bigger beers. And visible activity is a poor indicator of continuing fermentation. After a couple of weeks, check Final Gravity with a hydrometer; it's done when you get the same reading three days apart.
