CO2 Diffuser

[equidorz]

Hi guys,

I am facing a problem with my cermaic diffuser. I am using a solenoid regulator Co2 system. Few hours after i turn of the main switch of my Co2 system i notice that there is still bubble being release by the diffuser. There isnt any activity in the bubble counter. Anyone experience this before? Is there something wrong with my system or connection?

Thank you.

normal, it will be like that until the build up pressure equalize.

Hi Shadow,

Thank you for your reply. Do you mean that this is common? And how long will it take for it to stabilize? I do not face this problem in the pass so i was thinking that there might be something wrong with my diffusor or system? And can you explain what is means by pressure stabilize?

Thank you.

[equidorz]

Sorry, the word used should be equalize instead. My bad.

[Shadow]

should be less than 15 minutes, never actually timming it though. I'm not sure if equalize the right word either...

[equidorz]

oh, in that case i believe there might be something wrong with my system because even after hours after turning off the main solenoid bubbles are still seen. Anyway thanks for your help. Cheers!

[Shadow]

that sound like your solenoid stuck

[equidorz]

Oh, is there anyway that i can test or repair if its really faulty? else or do i need to change a new solenoid?

If there isn't any activity in your bubble counter it should just be residual pressure in the tubing.

How long is your tubing from the CO2 tank to diffuser? I'm assuming you're using the usual black CO2 hose?

If the solenoid is stuck or leaking you should be seeing bubbles still going through the bubble counter..

He said:

There isnt any activity in the bubble counter.

but his residual pressure last for more than 1 hour, unless he is using rubber hose which expand due to the pressure.

My tubing is around 1.3m from the co2 tank to diffuser. Im using the normal transparent rubber tube. Nope i dont see any bubbles going through the bubble counter after i turn off the solenoid but i still see bubble release through the diffuser. I got a feeling is solenoid stuck as shadow adviced.

Anyway i will go and take a look at the bubble counter again to check if there is any bubble going through the counter, maybe its less than 1 bubble per second thats why i am unable to detect any bubble in the counter.

Im using the normal transparent rubber tube.

Use tubing intended for CO2 application. They more rigid that the regular air tubing.

hhmmmm...That is wierdo. If there isnt any bubble for the bubble counter, therefore there is no bubble being released to your diffuser.

What type of co2 diffuser you are using?

[equidorz]

Hi herm. Thank you for your advice. I am using the transparent tubings because of the cost and of course the transparent tubes look nicer. Anyway I have check and confirmed that there are still bubbles in the counter after I switched off the solenoid, however the rate is like 3mins per bubble so it is hardly noticable unless you patiently for it to appear! Anyway can I confirm as per shadow that my solenoid is stuck?

Youre Welcome.

CO2 tubings are transparent. Take a look the pic.

What solenoid are you using?

Youre Welcome.

Hi Herns,

Yes i am using this kind of transparent tubings. Similar to what is provided in the picture.



What solenoid are you using?

Its a brandless solenoid i got from the local fish shop many years back.

Cheers

[herns]

Its a transparent tubing but this is for CO2 application. The one you are using is transparent as well but that is a regular tubing use for air pumps. Even both have transparent look, they are different.

[BFG]

To simplify, the co2 ones that you should use is harder compared to an air tubing that is commonly found at the lfs. Pressurized tubing is created to be tougher than their non pressurized counter-part.


Hope this helps!

Hi all,

Thank you for the prompt replies. I feel that it is not the tubing that is the root cause, it should be something to do with the solenoid. I might change the solenoid first. But on another note, i got a friend who is using a manual regulator and is also facing same problem as me. Im confused.

[herns]

BFG & I hear you clearly with that. We are just not trying to help you with your solenoid misery but also, we are letting you know the tubing you currently use is not intended for CO2 use.

Hi Herns,

Noted. Thank you for the useful infomations, but first i need to take care of the solenoid first.

Wee.
