Water Going Back to CO2 Airline?

[hmph]

Hi bros,i have started the practice of turning my co2 at night instead of running an airstone thru the night. Noticed that water is moving back (very slowly) up the reactor into the co2 airline towards the check valve and solenoid. Is this normal?

This is due to the continual dissolving of the CO2 in your airline. As CO2 in your airline dissolves in the water, water get pulled back up the airline.

Normal. Just put a check valve between bubble counter and cyclinder.
