8‑litre CO₂ cylinder with valve

This Aquario 8 l CO2 cylinder is a new unit, not a converted fire extinguisher or oxygen bottle, so it suits aquarists who want a documented, fresh cylinder for their CO2 supply. At 76 cm high and 14 cm in diameter, the supplier states it will fit in a standard aquarium cabinet.

Why it matters

• The cylinder is manufactured new and is not regenerated from older units, which the supplier notes are often decades old.
• The valve is the newest type, with a safety rating of 150 bar.
• The body is painted to PN EN 1089-3.
• The cylinder is legalized for 10 years from its production date and carries the Pi mark, which allows it to be refilled anywhere in the EU.
