I'm having a problem with my co2 controller setup that I'm hoping someone can help me with. I replaced my 5lb bottle today (swap). I noticed that when the solenoid switched off (has a red indicator light, outlet display light on the controller), the co2 kept bubbling through the bubble counter. It even kept going when I turned the dial on the bottle itself off.
There is often a good amount of CO2 in the line from the CO2 reg to the reactor, so even completely shutting off the CO2 tank main valve won't stop the flow right away. I typically will see bubbling for 4-5 minutes after shutting off the reg. If I crank open the needle-valve after shutting off the reg, I can bleed off the pressure quicker.
Turning the dial down on the needle valve hardly
makes and difference in the bubble rate. What's going
on here?
