I don't know where your check valve is, but I assume it's between your regulator and your bubble counter. In any case, pour some water into your airline somewhere before the bubble counter--check valve or regulator, whatever is easiest for you to pull apart--until you've got 6" or so of water in the airline. Reconnect airline, turn on CO2, watch the water in the line travel to your BC and fill it completely, and any excess water continue on into your diffuser or reactor.
