How long does your CO2 last?
I'm thinking about getting a 5lb. tank, regulator with a solenoid for my new 40b. I'm just curious how long your tanks last. I'm going 5 lbs. for cost reasons at this point... I know a 10 would be better in the long run... just can't do it right now. What size tank, bps, time on, etc. I know there are many many variables... just trying to get an idea
