| | When is there danger of an end-of-tank CO2 dump?
I have a 20lb tank with high quality dual regulator and needle valve. My tank was originally at about 900 PSI on the primary regulator, now after many months it's at about 300 PSI on the primary regulator, with a steady output of 60 PSI on the second regulator, which is controlled by a quality needle valve.
At what point is there a danger of end-of-tank dump?
Also, is there still a danger of end-of-tank dump if you use a quality needle valve? Won't the needle valve prevent this?
Is there as much danger of an end-of-tank dump with a smaller CO2 tank? I plan on switching to a 10lb tank when this tank is up, just to save space. With a solenoid it will last as long as my 20lb tank without one.
Thanks for your thoughts, I don't want to take out all of my fish because of a CO2 tank dump!
