UP Aqua’s Replacement CO2 Cartridge (1 single non-refillable cylinder or 3 non-refillable cylinder-pack) for the UP Aqua CO2 System kit is made of extruded aluminum. Each cylinder contains 95g of Carbon Dioxide, ideal for keeping your freshwater aquarium plants fed.
Important Info: Use teflon tape on any fitting that does not seal with a gasket or o-ring. DO NOT OVER TIGHTEN.
You get what you are paying for. Easy to set up. Consider paying the additional money to upgrade if you are looking for lower maintenance CO2 equipment. CO2 cartridges are more costly in the long run anyways.
