What size of CO2 tank?

I have a 180 with some sps and clams. What size tank, 5 LB, 10, 20?
How long does 10 pounds last for each of you and why?

I get 6 months out of a 5lb. Pretty good size and fits under alot of stands.

Thanks Don, that's good enough for me.

Yep, 5 pounder will last 6 months for me as well.

Thanks Dave, 5 it is. Getting tired of calcium chloride and 2 part buffers. Kalk is a pain without a spendy stirrer or PTA messy bag refills. Am starting with a cheapo Corallife Calcium reacter and will move up when a good deal on a larger better one surfaces.

As a side note, since I'm already looking at purchasing my second Ca reactor in the next year or so to keep up with Ca demand, I would look at the fluidized reactors or recirculating designs for their efficiency. A second chamber is also good for removing excess CO2 from the effluent, and lastly a john guest fitting on your skimmer for effluent to drip into to help blow off any excess CO2. Just something to keep in mind so you're not buying your second reactor in two years.
