CO2 regulation
C/H:
The cloudy stuff is corrosion caused by CO2. Carbolic acid. CO2 is extremely corrosive to plastic or silicone tubing. Try changing you tubing to NEW automotive brake line. This stuff is immune to CO2 corrosion. Do you have a bubble counter? If so there is likely a check valve built into the bubble counter and therwefore you do not need an inline check valve. If not consider a bubble counter with an integral check valve. This check valve will likely be stainless which is also immune to CO2. Was the inline check valve plastic? If so it is likely corroded by the CO2 and that is the likely reason for the flow stopage. The bubble counter is really useful in setting flow rate. If you do not want to go the bubble counter route get a metal check valve to terminate the corrision issue.
