Whats a Siphon Tank?
This is by far the most popular question and we have a separate topic for it. Simply put, ALL refill Donor Tanks must be of the Siphon type so that liquid CO2 can be transferred to the ALCO2JET bottle. Siphon tanks look identical to Gas only tanks, except that they have an internal Dip Tube that sucks up liquid CO2 from the bottom of the tank, and dispenses it through it’s CGA-320 Valve.
