Overview[]
A Water Tank is a Cargo item used by the Oxygen Garden to fill a station with oxygen and/or refill either an Oxygen Tank or a Carbon Dioxide Scrubber in the other slot of the Oxygen Garden.
It is pre-loaded into one of the two Cargo slots of an Oxygen Garden and two slots in the Stand-Alone Laboratory. The water tank can deplete but at a very slow rate; it is the only Cargo item that can't be refurbished and had to be replaced once it had ran out.
It has no known uses other than to be used in an Oxygen Garden to produce breathable atmosphere aboard space stations.
