So I got this on ebay for $140:

Milwaukee MA957 CO2 regulator & SMS 122 pH controller

I guess I need a reactor now. What do you recommend? I am limited on funds. Do most of you rent or own your CO2 tank?

I own mine. But I think your true cost is going to be in the reactor. The co2 bottle should be pretty cheap.
