VERY nicely done man. I just posted an article on our blog about how to use paintball canisters to have a cheap CO2 setup. Despite the price per volume, the nice thing about the paintball setups is that they can fit under your tank more easily than a full sized canister. Having said that, they are definitely a bit pricier. This article is just fantastic, and I think I will definitely link to it in the next few days
Thanks for sharing!
