i have a paintball co2 tank that id like to use for my setup. idk what to buy for it though. i found this:http://www.drsfostersmith.com/product/prod_display.cfm?c=3578+3747+15526&pcatid=15526 but idk if theres something better out there. any help?
If I'm doing my math right, a 5lb tank is 80oz which is 4x larger than a 20oz tank. I'd think that you'd get 4 times more length between refills or about 20 weeks for a 50-55g aquarium based on Oregon_aqua and my experience. That assumes you've got it on a solenoid that turns it off at night.ok how much longer would like a 5 lb tank last me?
