Help!Geo 612x2

[Jlombar1]

Hey y'all. Okay, I'm having an issue. Running a Geo 612x2. It was working fine until about two weeks ago. Now when I turned the pumps on (feed and recirculating), I'm getting minimal CO2 into the reactor. I could run it wide open, and minimal CO2. Seems like the back pressure from the pumps is blocking CO2 from entering the reactor.

I changed the check valve and that did not fix the issue.

Maybe you have a leak in the co2 feed hose?
You could replace all sections for little cost.
I assume your co2 tank is full and you have no issues with your gauges or regulator...

Is there water in the tubing between the outlet of the check valve and the inlet of the Co2 connection?
