UNS CO2 Paintball Cylinder - 24 Oz.

When you are managing a beautiful nano aquarium or a compact desktop scape, finding space for bulk equipment can be a real challenge. The UNS CO₂ Paintball Cylinder (24 Oz.) offers the perfect middle ground for hobbyists who want a long-lasting, refillable carbon supply without sacrificing valuable space around their display.

Key Features & Benefits

• A dedicated manual on/off twist valve gives you complete control over the tank opening, so you never have to worry about sudden leaks during installation.
• The 24-ounce capacity offers a compact footprint that easily tucks away into small under-tank cabinets, desktop setups, or tight shelving displays.
• Lightweight aluminum construction provides a clean, rust-free profile that safely handles the naturally humid air inside an aquarium stand.
• Transitioning to a refillable tank lowers your long-term operating costs and provides superior pressure stability compared to small disposable cartridges.
