co2 pressure dumping

[wayner]

I set up a Reactor 2 weeks ago, completely filled 5lb co2 bottle, when I started it up the guage read 750 which is about right I think for a full bottle, 1 week later, the needle has dropped below the 500 mark, has this ever happened to anyone?

I can only think that the regulator is faulty and the co2 is leaking somewhere, I did a test where you completely close off the valve on the co2 tank to see if you still get bubbles in your bubble counter, I still did which is suppose to mean that there are no leaks.

I'm confused, has anyone ever ran across faulty guages?, if there is a leak where it would be leaking from, I did the soap test before it was set up and no indication there that there was a leak.

Anyone know where to pickup guages for a regulator here in Calgary.
