Question about CO2 regulator

[7thheaven]

Hi All~

I use Harris dual gauged regulator with 2.2l co2 tank.

and you know there are two gauge in dual regulator and I wanna know the
right(proper) value of them..especially the left one value
(connect to CA reactor...second gauge(?))

Thanks..

The left one on my M3 set-up is tank pressure, mine 1000-1100 psi when full. Right side is line pressure (bubble count). Mine is set at 52 psi and runs at about 90 bpm. HTH

I run my low pressure side around 14 psi.

Thanks..Marshal and Chad W

Is it recommanded value in low pressure?

I'm sorry I'm afraid I don't understand your last post 7th heaven. I'll try and explain a little further . The high pressure gauge is the gauge that shows internal pressure of bottle. The low pressure gauge shows the line pressure being supplied to the reactor. It's been a little while since I have looked at my reactor manual but I would think your reactors owners manual would maybe have a recommended supply line pressure. HTH

The Korallin reactor recommends about 15 psi IIRC. My bubble count doesn't stay consistant at that low of a pressure. I use line pressure to adjust bubble rate. I just get the needle valve close to the right bubble count, then fine tune with pressure. Not the most common way, but it works for me.
