Co2 Tank Question

[vulkan]

What size co2 tanks do you use, what size is your tank, and how long do they usually last?

I was looking at smaller co2 tanks, such as a 5lbs / 10lbs / 15lbs but was unsure of how long the co2 would last assuming I'm doing 1 or 2 bps.

-Edit-

I also forgot to ask where a good place would be to buy fertilizer online in the US.
