CO2 bottle question

[marino420td]

I am about to set up my GEO 612 calcium reactor and I'm shopping for a CO2 bottle. My tank has total water volume of approx. 200 gal but mostly just sps frags now. I can get a 5 lb bottle with a regulator for $150 from another RC member.

I priced new bottles and a 10lb bottle new is $125 and I would still need a regulator.

Is the 5lb bottle large enough for my system?

Where is a good place to purchase a bottle? I checked local welding supply stores for my prices.

Anyone?

i'd go with a 10 lb bottle. Once those frags grow into colonies you'll be filling up a 5 lb bottle every couple of months.

I use a 5 lb and it lasts between 8 and 9 months.

I had a 5 pound and got tired of going to the gas refil station, so I got a 20lb.
