Yes, I store it separately but only because it's too tall to fit on the shelf with the regulator attached. Guess that was just lucky for me.

Aeration System Introducing lead and Lead Compounds into wort

Crack the valve open just enough see the slightest bit of churning on the surface. I set a timer for 2.5 minutes and shift the stone around every 15 seconds or so to make sure all of the wort gets exposed to the stream of fine bubbles. Make sure you are using a fine enough stone. I'm not 100% sure but I think mine is .5 micron and my beers are awesome

My $0.02...
#1- i too would use up a red disposable canister after only a few uses. I would always remove it from the regulator between uses. I think if one uses a wand and stone it lasts longer. When i use my spike conical and carb stone, i think it requires more pressure/force... which is more gas.
I am of the opinion that the amount of oxygen needed per 5 gallon batch is about 3 cans of that disposable brand.
At any rate, i moved to a steel tank of food grade oxygen... expensive, but it should last me forever now.
Side note- spike has some good info on their micron size and research (they use a 5 micron). I am too lazy to link it, but basically they noticed no difference.
To me there is no doubt the oxygen helps the yeast. Pitch rate too, temp control... all important parts of the processs. Ymmv.
#2- i am a California native. We call it Calunicornia now. When i rented cars, we had prop 65 on the door to the lobby. Because guess what... cars use gas, and gas can cause cancer.
It is on just about anything you imagine out here. As stated above... NO ONE pays attention to it.
This state is a JOKE. People are leaving in droves. Just google a one way uhaul into California, and a one-way out of California. It is about 10x the cost to leave here.

Let's just say we're big into birds.

In California they have warning labels on the air you breath because it might give you cancer.

As of 1/1/2021, a new law requires any cancer warning label with adhesive to also have... a warning label that the adhesive is known to cause cancer....
Yes- we are now putting warning labels ON the warning labels!
(Ok- not yet... but anyone wanna bet the over/under before we do? I'll take the under!)

Once this Prop 65 mess started in California the company I worked for simply stopped doing business with people in California. Too much paperwork.
Lead exposure from that device is probably almost non-existant but Prop 65 requires that label to sell it in California.

One other thing I haven't seen mentioned, the plastic in electric wiring casings can have led in it. As I understand it, it was banned at one time before someone lobbied to have it put back in. I believe it makes the plastic/rubber more flexible. It is also another potential reason for the label.

I am using a small air pump in my fermenter as well. I am fermenting sugar washes and the high sugar content reduces the oxygen capacity of the wash, aeration is an easy solution and the solution that large scale commercial operations producing high percentage ethanol for fuel use.
I also find it handy as I have a third tube coming from my fermenter dropping down to the middle of my wash and if I unplug it and pinch off my CO2 tube it builds pressure and forces wash out the third tube without opening and exposing my wash to potential contaminants in the air. This allows me an easy handy and sanitary way to test Ph as sugar wash has tendency to drop down to as low as 3.5 Ph after 2 to 4 days of fermenting.
If you use an air pump to aerate I suggest building a small sealed box with a HEPA filter to filter out any fungal or mold spores and any bacteria out of the air that you are pumping into your fermenting chamber.

It seems that it is a real thing. People with illnesses know better because they feel the difference on themselves, it's not just paranoia.

I suggest this...
Cheap (although one can get 4 for $10 on the amazon), easy, and disposable after a few uses.
I use it for oxygen, and in a rubber stopper with hole on my flasks for yeast starters.
