Help with CO2 Kit

[Melinda P]

Hello! I know nothing about CO2 set ups but wanted to try out the Fluval CO2 kit (I don’t have the space to the large set up that the CoOp offers).

 

I have set everything up as the instructions said and when I first turned it on it seemed to work, but now when I open the regulator, the water level in the bubble counter increases (and even overflowed a couple of times). I can hear the CO2 so it must be going somewhere but I have tightened everything and cannot figure out where the gas is escaping.
 

Any advice would be appreciated🙏

When you say it worked, did you see bubbles coming out of the diffuser?

You can run a soap test on the bottle / regulator and then try to fill it again.
