Hi RudeDogg1

There is someone round here who runs his bottles until they're empty on a JBL regulator, but I can't for the life of me remember who it is :oops: .
Hopefully he will pop by soon and confirm this.
I run a JBL system myself but have never been brave enough to run the bottle till empty :lol: . I always change it when the pressure gets down to around 20 - 30 bar.

i run mine till they stop with no problem, to be fair to the JBL gauges, they are very good.

Was reading a similar topic earlier in which Ceg stated that you shouldn't run them dry because it can get air / dirt / moisture into the CO2 bottle which could cause a weakness in the bottle, so just something to bare in mind.

I've run several systems to empty and never had a dump. Maybe thats just me, I know people have experienced it. The only thing I have noticed is that as the cylinder gets lower the pressure goes up so I get an increase in CO2 in the tank which I have to be careful of, not that its ever caused me a noticable problem with the fish or anything.
