Default CO2 Tank Problem

I just bought a 3L Aluminium CO2 tank from Y618 today. Followed the LFS staff's instructions to set up the CO2 system and it's bubbling well. Problem is, when i turn off the main valve at night (I don't turn off the Regulator valve), there is still CO2 bubbling into the bubble counter, and now I'm a little worried that maybe the main valve is not working well.

Is it normal for the CO2 to continue bubbling a while after the main valve is closed, maybe because of some pressure thingy? Or is the main valve faulty?

Please advice.

is very normal when bubbling occurs after u turn off the main valve.. is because when u turn off the valve, co2 that yet to release are slowly moving along the hose to the tank.. that for it will stop bubbling after 5mins or so.. get a solenoid instead of manual regulator unless u dun mind switching on and off ever night..

thanks very much bro.

but i found another problem. the pressure of the tank was at 1000 IB/In^2 last night. when i woke up this morning, i found that the pressure was ard 750. There is no more bubbling since i switched off the main valve last night, but how come the pressure in the tank dropped? can the tank be leaking?

does the pressure stated on the manual regulator drop when i switch off the main valve?

i've just switched it on 5 mins ago, but the pressure stated is still the same.
