Did you "soap" all the lines and connections to make sure there was no leak?

That being said, your CO2 is very small! With a 100 gallon tank, I would
expect a 10 pound bottle to more appropriate - myself, a 20 pound for a 55
gallon tank. Granted it is overkill but, the cost difference was minimal
and, when I upgrade to the tank I'm saving for, 225 gallon, I'll be set.
The 500 gram bottle would work for a nurse bottle when the main one is out
being refilled.

Hi All,
Two weeks ago I've bought my first pressurized CO2 system - effect was
tremendous!
The sad thing it that the bottle(500grams) is now empty - frustrating...
The pressure was about 0.8 bar, bubble per second till you could not count
bubbles anymore - water pushed out from the diffuser PH 6.8 plants and
fish
are happy. Did I do anything wrong in the setup ?
Vendor claims that it should last for 3 up to 8 months - depends on usage.
Is there a problem with the regulator ?
