Frequently Asked Questions
1. Does the UNS 16oz CO2 Paintball Kit arrive with gas in the cylinder?
No. Federal shipping regulations strictly prohibit the transport of pressurized gas cylinders. The included 16oz tank ships completely empty and must be filled locally at a paintball park, welding supply store, or homebrew shop before use.
2. How long will the 16oz paintball kit last before needing a refill?
On a typical nano or desktop aquarium (under 10 gallons) running a standard 1 bubble per second rate for 8 hours daily, a single 16oz cylinder fill typically lasts between 2 to 4 months.
Team Buce Plant Tips
Setting up pressurized carbon dioxide is far simpler than it appears! Explore our step-by-step guides to master your setup:
"I purchased this kit after doing a decent amount of research on CO2 systems and the different kinds available. The instructions with this kit were very straightforward and easy to follow with the videos on the UNS YouTube channel providing troubleshooting tips. The only thing I wished I had given a bit more thought to was getting the canister filled with CO2. All of the shops near me said it was too small or that they only do tank exchanges, and I ended up buying a 2. 5 gal tank from a brewery supply store. No fault of Bruce Plants there, all in all I would definitely recommend this kit if you have a paintball shop near you that will do refills, otherwise just buy the parts separate and get a tank from your local shop."

Faulty Canister.
"Everything works great. My only problem is that the canister cannot be filled because it is missing a piece it requires for the co2 to stay in the container. I’ve brought it to multiple stores near me and they’ve all told me they can’t fill it due to this issue. I don’t know if I just got a faulty canister or this is something that is with all the UNS canisters, but other then having to buy another canister from my local paintball shop, everything else works good I have no problems."
