The world’s pioneering CO2 system that made it possible to grow aquatic plants in aquariums.

Aquatic plants produce organic matter from carbon dioxide (CO2) and water through photosynthesis, and use the organic matter as a source of energy to grow. Therefore, the addition of CO2 to promote photosynthesis is essential for the healthy growth of aquatic plants. In this article, we discuss the CO2 system, an indispensable device for safely supplying CO2 to aquarium tanks.
CO2 System 74-YA/Ver.2
It’s a standard model CO2 system, also included in the CO2 Advanced System.
CO2 System 74-SA
A high-end model that can regulate CO2 discharge pressure between 0.00 and 0.35 MPa.
In order to establish a cultivation method for aquatic plants, ADA has focused on developing CO2 systems since its inception, and has created a revolutionary CO2 system using a small CO2 cartridge cylinder and CO2 regulator. In 1985, ADA commercialized the world’s first CO2 system that has made it easier for hobbyists to cultivate aquatic plants. In addition, it helps reduce the amount of carbon dioxide released into the atmosphere because the carbon dioxide gas filled in the small CO2 cartridge cylinders is produced by refining carbon dioxide from industrial exhaust gas, and used for photosynthesis of aquatic plants. Another feature of ADA’s CO2 system is its early adaptation of the components that ensure safety and performance, namely, the highly accurate speed controller and the floating needle that opens a small CO2 cartridge cylinder securely.
CO2 Forest Bottle
CO2 cartridge cylinder that comes with a refreshing scent reminiscent of a forest.
