Fermenting in a bucket, lid is on tight. I don't use an airlock, just tube out into sterilized water. When I push down a little on the lid, CO2 comes out. I've done this a couple of times since the original post to see if I could check the water level in the tube (to see if it was the same). Water level always dropped out of the tube, so it must be still making gas. Just went from super active to zero bubbles, but I guess temp had a lot to do with it. Recipe says to rack to secondary after 5 days, but I think I'll wait the extra week like everyone suggested.
