paintball co2 system question

[aquaria mania]

just wondering how long a paintball canister would last for a 20gal running approximatly 2 bps, or would it be worth it to step up to a 5lb tank. thanks for all info

Mine lasts a little over three months at a time with a similar (slightly higher) bps in my 20. Considering that I keep a full spare cylinder around and can just walk down the street to refill them it's ideal. If I had a business that refilled larger containers that close I'd use them. I love my paintball system and may get a second for my 5.5 gallon.

that sounds pretty good, i didnt know if the paintball systems lasted that long, and i didnt really want to go to big with the system and end up making it the focal point instead of the tank
