co2 Tank ?
 

I have a compressed 10 lb alumnium o2 tank in my garage and was curious if I could have this converted or just filled with co2 for a calcium reactor? Does anyone have any ideas if this acceptable?

Anyone?

I think so take it to a fireextinguisher place and ask them if it is rater high enough for pressure and if a CO2 valve will fit in it. they will probably charge you about 35 to 50 bucks for a hydrostat, fill and new valve
