These are two 80 g disposable CO2 cylinders with 5/8-inch threaded necks, sized for aquarium CO2 systems that take threaded cartridges. The 80 g fill is the largest common disposable size, so each cartridge lasts far longer than 16 g or 45 g cartridges and means fewer swaps on a planted tank. They are single-use: once empty, the cylinder is recycled, not refilled. They suit planted-tank owners with a threaded regulator or adapter; anyone running a pin-valve regulator built for small cartridges will need a 5/8-inch adapter.
