Aquarium Co2

Hundreds of fine white bubbles enter the planted tank, quickly whisked away by the flow of water, spreading over the aquatic plants like pollen over a field of flowers. Co2 is used by the aquatic plants and returned into the water as vital oxygen for fish, shrimp and microorganisms.

In 1985, Takashi Amano had a breakthrough that would forever change the world of planted tanks: adding Co2 from small cartridges to the aquarium. Co2 is necessary for the photosynthesis of aquatic plants – in fact, before the advent of Co2 systems for planted tanks, it was very difficult to effectively grow plants in the aquarium at all. Without it, growth stagnates and wilters with no reliable way to grow a dense forest of aquatic plants.

Aqua Design Amano developed the world’s first Co2 system for planted tanks back in 1985 – starting with small disposable cartridges and regulators. Today, while the equipment has been fine crafted and polished with an elegant design, the spirit of that very first system is alive and well in all our products.
