Taking the advice of the fine folks at TBN, I've just purchased an oxygen tank, a regulator, and a .5 micron stone. I'll be brewing with it for the first time tomorrow. Today, I hooked it all up and tested it with a small cup of water, and the air flows and makes really nice tiny bubbles. Excellent. Now, the question is, how do I store the thing? I tried removing the small hose from the regulator so I could coil it back up and place it back in the ziplock bag it came in, but it looks as it it's not made to disconnect once you've put it on the regulator. The owner of my LHBS told me to make sure to never touch the stone, because the oils in my hands could block the pores, so I'm trying to be very careful with it, but if I can't remove it from the regulator, what can I do? Is it safe to remove the regulator from the tank? Or will it then just release all of its oxygen? Or should I just coil the hose up around the tank and just store it like that, taking care not to touch the stone to anything?
Also, the small document that came with it said that I could clean it by backwashing water through it. I have no idea how I would go about doing that. Can I just soak it in starsan to clean it?
