I'm new to all grain and in the process of improving the quality of my beer and reducing the duration of my brew day. Currently, I have an aquarium pump with a diffusion stone and oxygenate my wort with air for 30 minutes before I pitch. The pump is similar to this one from Northern Brewer:

Yeast: The Practical Guide to Beer Fermentation by Chris White and Jamil Zainasheff, I learned that I should shoot for 8-10ppm of oxygen and that pure O2 is more efficient than an aquarium pump. So I had a few questions on what I need in assembling my system:
1. What size O2 tank is best for oxygenating?
2. Where is the best place to get a tank? Can the tanks be purchased or rented? Which is best?
3. What's the best flow meter for the tank?
4. What size diffusion stone is best for oxygenating wort? Can I use the one from my aquarium pump system?
5. Should I use a wand or tubing to connect the tank to the stone? I have heard that the wands are difficult to sanitize.
Let me know what you all think. Thanks for your help.
