2.5 lb CO₂ Program Tank

Our 2.5 lb CO₂ Program Tank is a compact, convenient option for draft systems, home carbonation, and aquarium CO₂ setups. Its smaller size makes it easy to store, easy to move, and especially useful anywhere space is limited.

For draft beer and beverage dispensing, a CO₂ tank provides the pressure needed to push beer, cider, sparkling water, or soda from a keg to your faucet. Connect it to a CO₂ regulator, attach your gas line, and you’ll have the controlled pressure needed for pouring, carbonating, and maintaining your beverages.

This size is also particularly popular with aquarium users, especially for planted tanks. CO₂ supplementation helps aquatic plants grow more vigorously by giving them access to the carbon dioxide they need for photosynthesis. A 2.5 lb tank is a great fit for many home aquarium setups because it offers more capacity than very small disposable cartridges while still being compact enough to fit neatly beside or inside an aquarium cabinet.

Because this is part of our CO₂ tank program, you don’t need to worry about finding a fill station or dealing with expired tank certification. When your tank is empty, bring it back and swap it for a full one. It’s quick, simple, and keeps your setup running without the hassle.

A 2.5 lb CO₂ tank is a smart choice for:

• Home kegerators and small draft systems
• Planted aquariums
• Portable beer dispensing
• Carbonating water or soda
• Small kegs and mini keg systems
• Carbonation caps and PET bottle carbonation

If you’re running multiple taps, a busy draft system, or a large aquarium setup, a 5 lb, 10 lb, or 20 lb tank may be a better fit. But for compact systems, occasional use, and aquarium applications, this 2.5 lb program tank is an easy and practical choice.

Please note: regulator, gas line, disconnects, aquarium diffusers, and fittings are sold separately.
