well the tan water is PH 6.8, GH 10 Don't know the KH yet - which I must
know....
The diffuser is like a glass shaped bell with a hard membrane that diffuses
the gas.
At first I could really see and counted the bubbles but after a few days no
more bubbles and there was only gas in the diffuser, this made a bit concern
but I did measure the PH twice a day was ok, no signs of stress so I figured
I was doing ok...Maybe I did Bubbled to much ? Not all of the bubbles were
fully diffused as you could see tiny bubbles at the water surface.

if it wasn't a leak, you may be bubbling too much, but without water
parameters, can't tell ya... the only way I can get water pushed out of
the
diffuser is to open the regulator wide open, where it's pushign more CO2
out
than the water can 'absorb'

post your water parameters, your tap water and some guru here will chime
in..

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 ?
