I'm planning on purchasing my first a CO2 cylinder and regulator. My question is can my tubing be attached directly to the standard commercial regulator and go directly to the aquarium diffusor, or do I need some sort of step-down aparatus between the regulator and aquarium. Also, I have several aquariums and would like to use the same cylinder for all, so can I use the typical aquarium valves that we use for air-stones etc,to direct the CO2 to 3 aquariums.
Also, in the Montreal area I can't seem to find any place other than Praxair for my cylinders, and the smallest they provide is 20 pounds. Any idea how long a cylinder this size would last for a 65 gal. aquarium? And, if there's anyone from Montreal (or even Canada) on this forum, do you know of another location for a cylinder. I would preferably like to purchase a 5 pound cylinder that I keep instead of recyling a monstrous 20 pounder.
Last question: Would you suggest CO2 cylinders over carbo-plus?
