I bought a Whisper aerator from MoreBeer and tried it out yesterday. Should I be able to see bubbles coming out of it in my fermenter? The instructions cautioned against excessive foaming but it did not produce any foam at all and no visible bubbles while it ran. Oh, and, the pump was plugged in, it was vibrating and making some sound, and I could see a few very small, very slow bubbles when I later checked the stone in my sanitizer. It just didn't seem to be doing much when it was in my fermenter...
