Hello! I have a Kegco 5#/5 pound CO2 tank for sale. It is full and has a current hydrotest of 01/2023 so you can refill it in the future if you need it! I actually took it to a store that specializes in hydroponics/gas and they told me that the tank was "very full," if that means anything.
Local pickup at New Destiny Church 625 8th St, Oakland, CA 94612 or delivery in the Bay Area for a fee!
