Inline Bubble Counter Help..

[jacko_oafc]

Just received a bubble counter from HK.
Its an inline one.
Link is here ( i did not get a check valve ),

I put it in the co2 line outside the aquarium between my co2 bottle and ceramic diffuser inside the aquarium.
I filled the bubble counter with water ( about a quarter way up, it will only fill so much ) and connected it all up.
I cannot see any co2 bubbles at all inside the bubble counter.
Can anyone help me with this ?

Buy a check valve, otherwise the water will go into your CO2 bottle. It wont go down the tube at the moment because there is pressure from the CO2 keeping it in (hence why you could only fill it so far).

I am presuming you have a fermentation kit?

What mixture did you use and how old is it?
