CO2 tank replacement

[hzheng33]

so the saltwater has done its toll on the co2 tank and although functional, I would like to replace it. where can I trade in the co2 tank? willing to pay a bit for the trade as well

When you say that saltwater took it's toll is it pretty badly corroded? Might affect being able to trade it in. But yeah I would try...

AirGas
PraxAir
NexAir

Also heads up most of these places won't trade/accept a tank that does have a current hydro-test date.

I swap mine out each time it gets filled at my local welding supply place.
