Particles coming out of new CO2 Tank... I'm a nuts?

Been using a 10# tank on my keezer that I got via an exchange from my local Airgas store and have had zero issues. I recently purchased a spare 5# tank (new) to use for random CO2 needs, transferring sani to kegs, pressurizing kegs to store and so on.... was hooking up and testing a gas line for the new tank and when I release C02 through the regulator I notice particals coming out of the hose. I got this tank filled at my LHBS. Am I seeing frozen co2 particles or is it bad CO2 or nasties in the tank???? Don't see these coming out of the tank from Airgas.

 

Probably frozen C02. But to be sure spray some in a glass carboy(so you can see it) and just see if it goes away after a little time. If its frozen C02 then they will evaporate.

I'm gonna guess its a C02 tank that was slightly overfilled.

Jaybird you are a genius
Think over fill was the issue. Curious if it had something to do with me bringing a boiling hot empty tank (left in my SoCal trunk all day) to get filled. Released some pressure from the tank and no longer seeing the particles. Sure it was just frozen CO2 now.

Thanks!!

 

That's the kind of thing that drives a regulator set batty when coupled up to an overfilled cylinder (bt/dt). Usually can be cleared up (or avoided in advance) with a couple of short blasts of the uncoupled cylinder valve...

Cheers!
