A special cartridge containing concentrated carbon dioxide, designed to be placed in the saturator to saturate the water with the gas. The cartridge has the form of a cylinder and is made of lightweight aluminum. It is mounted on the back of the device. To add bubbles to the water, you only need to press a button. Both the cartridge and the device operate without the need to connect to a power source.
The cartridges are filled with 425g of carbon dioxide. Their capacity is enough for about 60 liters of carbonated water, which is equivalent to 40 bottles of 1.5 liters each. The gas bottle is compatible with the Hydrospark saturator.
