I am venturing into pressurized CO2. I have purchased a Milwaukee regulator. Now I need a co2 tank. My question is, are the tanks that are
used for beer/soda appropriate for aquarium use? I found a 5 lb. aluminum one on e-bay that is reasonably priced. It is new and never been used. But it is listed for soda/beer. Is this the type to use for an aquarium? Or is there a special one?

Thank you both for your help. I will ask about the date. I haven't bought it yet because I wasn't sure if it was what I needed. Thank you again!
