It's probably not relevant, but I thought one of my fermenters had started fermenting again. It turned out, I believe,
that it was just a rise in ambient temperature pushing some gas through the lock. The SG never changed.

If it is fermenting, pressumably it will throw a little sediment over time so you may be able to check that way too.
