Reply With QuoteNormally, there should be another check valve bubble counter and the diffusor/reactor/etc.
hey folks
my Co2 setup is like this
Co2----->JBJ regulator----->check valve-------->bubble counter------->cheap ceramic diffusor
as i have yet set up my tank, i left the diffusor inside my 2x1x1.5 tank, not connecting with the timer.
Today, i saw the air tube connecting the counter to the diffusor filled with water. Why does this occur?
Is it due to pressure from the water in the tank?
Did i hook it up wrongly?
please advise.

I've more leaves in my tank!
Hmmm, I having the same setup with you. Mr Chan from NA helped me setup one. Shouldn't be a problem.
was the co2 turned on?
could be due to co2 being absorbed by the water thus causing back siphoning. also the water pressure will push water through ceramic diffuser and up the tubing.

Are you using the bubble counter with built-in check valve in brass construction?
If so, you are not the only one out there!
I encountered the same problem too!
I figured out that the setup is hooked up correctly!
So only left with 1 possibility, the check valve is not functioning as expected of it!
Wat I did was to in between the airline, inserted another check valve to counter this problem!

I used to have an airline to diffusor directly from the cylinder. The water can backflow into the airline... Quite dangerous to have water inside the airline and then try to force it back into diffusor. I had several mini 'explosions' while the water is being forced back, blowing the diffusor off and scaring the fish and me!...

That bubble counter has the check valve in the base of it, to prevent water in the check valve from back flowing intot e regulator. It does the same job as the check valve in gregorsamsa's setup. There is no check valve in that counter to prevent back flow from the diffusor.

thanks for the response.
i have just bought another check valve to be just sure that no water flows back.
i am using the normal plastic bubble counter. I am sure that the water does not flow into the solenoid. However, by virtue of the water flowing back into the airtube, it will dramatically increase the time needed for Co2 to get into the tank.
You likely have a leak somewhere along the tubing joints.

I usually put the check valve after the bubble counter, but for your case, I think the check valve has some leak.
Pardon me for being lost. Is it correct that 2 check valves are required- one before and one after the bubble counter?
yes, I too have 2 check valve 1 before and 1 after the bubble counter
leak. Hmmm.
will look into that. I suspected a leak initially too when I realised that the my gauges registered falling pressure despite the solenoid being deactivated. the pressure should remain constant through the night from what i rmemeber. thanks people for your help.
