diffusion stone

[bcryan]

i just bought my first diffusion stone. i just took it out of the package and was wondering if its transported with a cap over the stone for protection. it doesnt seem porous??? instructions doesn't say anything about removing anything?? anybody know what i'm talking about? cheers

The holes are small enough that you cannot see them?

I would imagine the plastic cap would come off. I didn't see a single image of a diffusion stone with one on and none of them look porous. Worst case, you put the cap back on!

The stone that I bought is stainless, a paper with it said not to touch it as the oil on your skin can plug the holes.

can you blow through it?

the fine stainless aeration 'stones/wands' out there do indeed look solid.

Yeah I have a .5 micron. It looks solid but it isn't. Remember .5 micron is freaking small...

To put it in perspective, .5 micron is .0005 mm or .00002 inches.

remove the cap before using and it is plenty porous for the O2.
