Co2 system regulator

Is there something wrong with the gauge on the left? Shouldn't it be on 10? If I turn the black knob all the way to the right, co2 will come out of the left(4th pic) opposite of the bubble counter I have it running 3bps. Is that enough for a 125g tank?

Not sure on the pH controller, never used one.

But, it sounds like the relief valve is being triggered. Is the solenoid on? You should be able to crank the pressure up (on the guage on the right) to about 10lbs or so, then slowly open the needle valve until you get your desired flow. If it keeps triggering the relief valve, I'd start by taking the needle valve and solenoid off and seeing if you can blow anything out, then put the solenoid on, try, then put the needle valve on. There may be something blocking it.

It sounds like the high side is open too far. I don't think there is anything stuck in it.

The alarm blinking just means the controller is on.

What do you mean by the high side is open too far? What can I do to fix it?

I've tried that. Turned off the solenoid and needle valve then turn the black knob to the right and it'll just go out the relief valve.

What fort is saying is you have your pressure turned up too high. Unscrew the knob until it is really loose (it'll come all the way off). Then, slowly screw it in... it only takes maybe a full turn or so to get to 10lbs on mine.


But, my post was under the assumption you're not getting any flow to the bubble counter. I guess, that'll help to know.

Adjust so that the right side gauge reads around thirty. Was the regulator valve closed when you opened the co2 tank?

I read on the link that you gave me to turn the black knob to the left until there is no tension before opening the co2 tank. That's what I did. But look at the right valve. Should it be like that? Shouldn't it be on the other side of the stopper when it is turned off?

Do I need to turn the solenoid off before I unscrew the knob? How many bps for a 125g tank?
I have it running 3bps
