Good To Know

• Check with us before ordering whether the cylinder ships empty or filled.
• Keep CO2 cylinders upright, secured and away from heat and direct sun — never leave one in a hot car.
• After fitting, brush soapy water over every joint; bubbles mean a leak that needs re-tightening.
• Have cylinders inspected when refilling; never use one that is dented, corroded or has a damaged valve.
• Too much CO2 suffocates fish — if they gasp at the surface, stop the gas and increase surface movement at once.
