    Left gauge should show 1000psi, it's the pressure of the CO2 inside the cylinder.

    Right gauge should be around 30psi, it's the pressure of the regulated CO2.

    Hi Terrance,
    Can you elaborate more on "it's the pressure of the regulated CO2"?
    Thanks.

    The gauge on the left measures the content pressure in the cylinder.
    When your cylinder is newly filled, it should be > 1000 PSI.

    As the pressure of the cylinder is usually high, and difficult to work with, the solenoid regulator will step down the pressure to around 30 PSI which is much easier to control

    The gauge on the right measure the working pressure output which is around 30 PSI. Which is to say that you are actually working with only 30 PSI instead of >1000 PSI. The PSI that you are working with is usually factory set!

    May I know the stepping down process is down in which part?

    Does that mean right gauge will measure the pressure in Part B?


    Part A= ?
    Part B= ?
    Part C= needle valve
    Part D= electronic valve to allow CO2 flow into 'C' by on/off eletricity.

    Thanks.

    A = Regulator
    B = Solenoid Valve
    C = Needle Valve
    D = Solenoid Coil (wires)

    1)The stepping down of pressure is done in the regulator.

    2)Yes.

    Regards

    Shiyong, there is somthing missing in the pic!
    Are you operating you CO2 system without a bubble counter?
    Or izzit you have it somewhere else?

    My question might sound stupid, but i ever seen LFS connect the airline straight to the outlet of the regulator w/o bubble counter and worse still w/o diffusor!

    Moreover, JBJ solenoids usually come with bubble counter that fix nicely on to the output!

    Sounds familiar, Colourful Aquarium? (beside NA that one)

    Most? I thought they were rare. NA sold me the JBJ regulator without the bubble counter, and most JBJ regulators I've seen online did not have the brass bubble counter that was supposedly attached.

    Hi Evolim,

    Taz_boy is correct, the bubble counter is outside the picture.
    Thoses items I have but outside the picture after needle vavle:

    needle vavle->check valve -> bubble counter -> check valve-> external reactor-> tank.

    according to LFS, the brass bubble counter has quite a number of failure cases, imagine if there is any leakage, the water will go down direct to part D (Solenoid Coil).

    Thanks kindly.

    You are rite!
    Din thought of that!
    Thanks!
    Think i gonna remove my bubble counter then!

    Colourful Aquarium does that?
    I tot the uncle quite knowledgeable one!
    His planted tank in the back of the shop looks fine to me!
    Will pay more attention to his tanks the next time i go there!

    Anyway, i saw mine in Serangoon area!
    The shop jus oppsite the new community center!
    There is also this Indian uncle that speak Hokkien tending the stall!

    I tot all JBJ solenoids will come with the brass bubble counters?
    That was that is written on their website!
    http://www.jbjlighting.com/pdfs/CO2_Manual.pdf
    When I bought mine, it came with the bubble counter!
    Or and I jus lucky?

    hi all, it may sound a little basic here, but is the function of the bubble counter only to gauge the outflow (bubbles per second)? If so, you may only need it at the start? My bubble counter dries up and i don't bother to fill it with water. Basically i judge the CO2 by the bubbles from my diffuser.
    There will be no more deaths after the holocaust. Of course, having 3 fishes in my 400L tank helps.

    For me, the bubble counter does have a built-in check valve, therefore, it also prevent the water from the tank to siphon back to the solenoid, causing damage to the solenoid!

    I think no one would ever want that to happen!
    If not I must save up for another few months before i can get another solenoid!

    Yes, and I believe it sort of acts like a check valve too. (not sure)

    It's not a compulsory peice of equipment to have, I don't use one; I do the same as you and read bubbles from my diffusor.
