Topping up of CO2 cylinder

[hebi]

hi guys. do you all know which LFS provides on the spot top-up of CO2? i understand that some requires you to leave the tank there and collect a few days later. also, is it best to get a top-up at the LFS which you bought the cylinder from? thanks

NA provides one to one on the spot exchange, this is provided you're using the black and silver canister.

hmm ok thanks. let say i buy the cylinder at other LFS, i can still go to other LFS to top-up right? regarding NA, the black and silver canister can only be bought from there?

cylinder can be top up at any lfs, but its better to leave your tank at the lfs, if you do instant top up of co2 normally the tank wont be full, maybe 3/4full or even half. but if you leave it at the lfs they normally bring the tank to factories to process, not too sure what process is that but i know it involves freezin the co2 something like that..
