I'm guessing that you are seeing water backing up the CO2 inlet when the CO2 is off (overnight)? This is normal due to the filter running 24/7. Simply install a check valve close to the reactor and this will stop any water from reaching the regulator.
If the water is backing up during CO2 use (day time), you will need to increase the regulator pressure to compensate.
Please let us know.
