UNS CO2 Cylinder Pro - 5LB
The UNS CO2 Cylinder Pro (5LB) is a compact, heavy-duty aluminum gas tank engineered to give planted-tank hobbyists reliable, long-lasting CO2 delivery without the bulk. Lightweight, corrosion-resistant, and easy to handle in humid cabinet environments, it is the ultimate sweet spot for dedicated pressurized systems. Features manual on/off twist valve, brushed aluminum construction, versatile 5LB capacity, DOT3AL certification, and universal CGA320 threads. On a 29- to 40-gallon planted aquarium, a 5LB cylinder typically lasts 6 to 9+ months before refilling. Sold empty due to federal regulations; must be filled locally before use.
