CO\u2082 Cylinder 2 kg (without siphon) \u2013 Suitable for Aquarium Use<\/strong><\/p>\n

The aquarium CO\u2082 cylinder is essential for maintaining a healthy aquatic environment.<\/p>\n

More specifically, carbon dioxide is necessary for plant growth. In its natural form, CO\u2082 is a gas, but like oxygen it dissolves easily in water. Aquatic plants use this dissolved CO\u2082 for photosynthesis in a similar way to grass or trees in a garden. Diffusers use membranes or reactors to dissolve CO\u2082 gas bubbles directly into aquarium water, creating an ideal artificial environment for aquariums.<\/p>\n

This CO\u2082 aquarium cylinder is equipped with a built-in safety valve, making it suitable for long-term use.<\/p>\n

Our used cylinders are fully safe, have undergone hydraulic testing, include a new valve assembly with tap, and are more economical than new ones.<\/p>\n
